SoutheastAAlabamaResidence Laboratory confirmed COVID-19 cases and probable cases. Confirmed cases of COVID-19 represent persons who have positive PCR tests, whether symptomatic or not (9/30/2020) Cases classified as Confirmed Cases had SARS-CoV-2 detected using a molecular amplification test (e.g., PCR, NAAT, RNA). (1/26/21)

The total number of confirmed and probable cases [note: As of 7/29, AL no longer seperates confirmed and probable cases].

Cases are classified using the CDC case definitions. Confirmed cases had detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ribonucleic acid (RNA) in a clinical using a molecular amplification test. Probable cases: 1) had SARS-CoV-2 detected using an antigen test* OR 2) is known to be a close contact to a COVID-19 case or was known to be part of an exposed group and meets clinical criteria. (08/23/2021) OR 3) COVID-19 was listed on their death certificate as an underlying cause or significant condition contributing to death.(09/20/2021)
When a death occurs in a person who tested positive for COVID-19, the record is reviewed by an ADPH physician to determine factors related to deaths and whether the death is attributable to COVID-19. This investigation must be completed before any death is included in our official data. If the death is determined to be COVID-19-related, our dashboard will show this. When a death occurs in a person who tested positive for COVID-19, the record is reviewed by an ADPH physician to determine factors related to deaths and whether the death is attributable to COVID-19. Death investigation can take one hour or less once the medical records are received.

Alabama also reports probable deaths. Probable deaths are deaths among probable cases; COVID-19 ws listed on their death certificate as an underlying cause, but has not had confirmatory testing. (9/30/2020)

“Confirmed deaths are deaths among confirmed cases. There may be delays in death reporting due to receiving information from hospitals, coroners, and other entities who send records to ADPH. Upon further investigation, some deaths may be removed from the data count, as there may be duplicate records, deaths that were reported as COVID-19 but are found not to be attributable to this virus, or in rare instances, a death may be reported and the person is not deceased. (1/2021)

The total number of confirmed and probable deaths [note: As of 7/29, AL no longer separates confirmed and probable deaths].

Deaths are classified using the CDC definitions. Confirmed deaths had detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ribonucleic acid (RNA) in an autopsy specimen using a molecular amplification test. Probable deaths: COVID-19 was listed on their death certificate as an underlying cause or significant condition contributing to death. (8/23/2021)
As of 9/20/2021: Deaths are the total number of deaths among confirmed and probable cases. Deaths that meet laboratory or vital records criteria not previously identified as cases are added to the case total. (9/20/2021)
Probable cases of COVID-19 currently represent two groups. One group categorized as probable cases is persons who are epidemiologically linked to a case (exposed to a person who had COVID-19), have symptoms compatible with COVID-19, and do not have diagnostic tests performed due to individual decisions or other reason. Another group of persons categorized as probable cases are persons who have had rapid antigen tests performed. (9/30/2020)

Probable cases: Cases classified as Probable Cases either 1) had SARS-CoV-2 detected using an antigen test*, 2) is known to be a close contact to a COVID-19 case or was known to be part of an exposed group*, or 3) COVID-19 was listed on their death certificate as an underlying cause. *If someone meets probable criteria 1 or 2 but has a negative molecular amplification test (e.g., PCR, NAAT, RNA), they are not a case.

The Alabama Department of Public Health recently onboarded a new laboratory. When new laboratories are onboarded with the Department, we sometimes will receive a backlog of results, both positive and negative. The increase in Confirmed Cases on the Dashboard August 29th reflects 1,297 positive cases from one backlog..

On 10/05/20, Alabama reported that a new lab began reporting, resulting in a backlog being processed which: "increased our daily number of cases for October 2 and our cumulative total for our October 3 dashboard update."

On 10/23, Alabama processed a backlog of nearly 4000 cases dating back to June.

11/14: The ALDPH processed a backlog of 109 positive antigen results from a facility in Tuscaloosa on 11/13; reported as "probable cases" on 11/13 even though tests performed between 10/23-10/30.

11/15: The ALDPH processed a backlog of 152 positive PCR results from a facility on 11/14; reported as "confirmed cases" on 11/14 even though tests performed between 7/23-11/13.

"Case counts and deaths reported on today's update are high;" represents a delay in reporting to the ADPH due to the holiday weekend. (12/1/2020)

12/01/20: Processed a backlog of 706 positive PCR results from a facility on Dec.1; classified as confirmed COVID-19 cases reported on 12/1 even though the tests were performed during 11/23-11/29.

Confirmed cases of COVID-19 represent persons who have positive PCR tests (8/5/2020)

Confirmed cases meets confirmed laboratory evidence (8/5/2020)
A probable case is defined as: (1) A person meeting clinical criteria AND epidemiologic evidence witn no confirmatory lab testing performed for COVID-19; or (2) A person meeting presumptive laboratory evidence (e.g., a positive antigen test) AND either clinical criteria or epidemiologic evidence as well as (3) meets vital records criteria with non confirmed laboratory evidence for SARS-Cov-2 (8/5/2020)

A probable death is defined as: A person meeting vital records criteria with no confirmatory laboratory testing confirmed for COVID-19. (8/5/20)Residents.No "As case surveillance continues at the local health department level, it may reveal that those tested in a certain county may not be a resident of that county, or even the state as an individual in question may have crossed the state border to be tested. "Around 3/31/2021, an audit of death certificates revealed 20+ COVID-19-related deaths that were not previously reported to DHHR.

Around 4/27/2021, DHHR's epidemiology team conducted a reverse death match by pulling official death certificates. Due to this review there has been a reduction of 162 deaths from the dashboard as these death certificates did not officially list COVID-19 as the cause of death. This update reflects consistency with the CDC reporting and provides a more accurate reflection of COVID-19 deaths in WV.

"A confirmed case – what DHEC has been reporting – is an individual who had a confirmatory viral test performed by way of a throat or nose swab and that specimen tested positive for SARS-CoV-2, which is the virus that causes COVID-19. A positive viral test, also called a PCR test or molecular test, alone is enough to classify a confirmed case.
A probable case is an individual who has not had a confirmatory viral test performed but has:
1. epidemiologic evidence and clinical evidence of infection, or

2. a positive antibody blood test and either epidemiologic evidence or clinical evidence. (A positive antibody test alone is currently not a reliable method for diagnosing a COVID-19 infection.)"

Confirmed cases of COVID-19 represent individuals who had a confirmatory viral test performed by way of a throat swab, nose swab, or saliva test and that specimen tested positive for SARS-CoV-2, which is the virus that causes COVID-19. (9/14/20)
A confirmed death is an individual whose death is related to COVID-19 and who tested positive with a confirmatory viral test for COVID-19. (9/14/20)Probable cases of COVID-19 represent individuals who have not had a confirmatory test performed but has: (1) a positive antigen test from a respiratory specimen AND (2) met clinical criteria of infection and is at high risk for COVID-19 infection. (9/14/20)A probable death is an individual whose death certificate lists COVID-19 disease or SARS-CoV-2 as a cause of death or a significant condition contributing to death but did not undergo confirmatory viral testing.

All data are preliminary and are subject to change based on additional reporting, which can happen at any time. A test may occur in one county, but later be reassigned to the county of residence for the individual tested. This is common especially in neighboring counties. Sometimes a test may be removed from a county when an individual is later confirmed to be a resident of another county. ZIP code data reflect the person's place of residency in Maryland. ArcGIS is the platform that supports the data dashboard, drawing data from iMap to determine ZIP code information. (12/18/20)

WisconsinNot SpecifiedConfirmed cases are those that have positive results from diagnostic, confirmatory polymerase chain reaction (PCR) tests or nucleic acid amplification tests (NAT) that detect genetic material of SARS-CoV-2, the virus that causes COVID-19 (classified using the national case definition established by the CDC). All data are laboratory-confirmed cases of COVID-19 that we freeze once a day to verify and ensure that we are reporting accurate information. These numbers are the official state numbers, though counties may report their own totals independent of DHS. (01/26/2021)Deaths must be reported by health care providers, medical examiners/coroners, and recorded by local health departments in order to be counted. (Meet the vital records criteria set forth by the CDC and Council of State and Territorial Epidemiologists (CSTE) case definition -- deaths that have a death certificate that lists COVID-19 disease or SARS-CoV-2 as an underlying cause of death or a significant condition contributing to death). (01/26/2021)Probable cases include individuals who have symptoms consistent with COVID-19 and an epidemiologic link to a confirmed case, but do not have a positive diagnostic laboratory test for COVID-19.

A person is counted as a probable* case of COVID-19 if they are not positive by a confirmatory laboratory test method (for example, a PCR, or NAT test), but have met one of the following (updated 8.19.20):
1. Test positive using an antigen test method.
2. Have symptoms of COVID-19 AND known exposure to COVID-19 (for example, being a close contact of someone who was diagnosed with COVID-19).
3. COVID-19 or SARS-CoV-2 is listed on the death certificate. (01/26/2021)
Deaths among probable cases are those that meet one of the following criteria:
1. A probable case of COVID-19 is reported to have died from causes related to COVID-19.
2. A death certificate that lists COVID-19 disease or SARS-CoV-2 as an underlying cause of death or a significant condition contributing to death is reported to DHS but WEDSS has no record of confirmatory laboratory evidence for SARS-CoV-2. (01/26/2021)

Probable cases are those who test positive by other testing methods such as antibody or antigen, and have recent symptoms consistent with COVID-19, indicating a recent infection.

Probable deaths are those individuals with a designation of COVID-19 as a cause of death on the death certificate, but where no confirmatory testing was performed.

(2/2021) As of August 1, 2021, in accordance with an updated CDC/CSTE surveillance case definition, a confirmed case is defined as a person who tested positive by molecular detection (e.g., PCR, NAA) or identification of SARS-CoV-2 through genetic sequencing. A person will be counted as a new surveillance case (e.g. reinfection) if they test positive for SARS-CoV-2 by a diagnostic test (i.e., molecular, antigen) and it has been greater than 90 days since the previous positive diagnostic test. In addition, a person with sequencing results identifying different SARS-CoV-2 lineages regardless of the time since the previous specimen sequenced will be counted as a new surveillance case.(8/16/2021)
KDHE has two processes for verifying COVID-19 related deaths. Notifications of deaths in COVID-19 patients may be reported directly to KDHE by local health departments or providers and are marked in our disease surveillance system. When the death certificate is received by the KDHE OFfice of Vital Statistics, we verofy the cause of death and date of death in our surveillance system. In the second process, we regularly review COFID-19 deaths in the death registration system and update any COVID-19 deaths missing in the surveillance system. In both processes, the death certificate data is the final source of data. Therefore, the number of deaths reported here by date of eath may not match the total number of deaths reported if the date of death has not been verified yet from the death certificate.As of May 7, 2020 to August 31, 2020 :Probable case is defined as a person with a) A positive serology test with COVID-19 symptoms or epidemiologically linked to a confirmed case, or b) No lab test with COVID-19 symptoms and epidemiologically linked to a confirmed case. As of September 1, 2020 A probable case is defined as a person with: a) presumptive lab evidence (antigen) or b) no lab testing but meeting clinical case criteria and is epi-linked (see CDC/CSTE surveillance definition). (2/2021) As of August 1, 2021 a probable case is defined as a person with: a) presumptive lab evidence (antigen) or b) no lab testing but meeting clinical case criteria and is epi-linked.(8/16/2021)Probable deaths are not reported by the state of Kansas.

As of Feb 23, 2021 - Reports any positive test. This can include the same individual multiple times. (4/23/21)
"We report a death when someone tested positive for COVID-19 and has not recovered. The death is reported through local public health notice or death registration"

There is a change in the way Iowa is recording deaths.
"Under the old system, the state recorded a COVID-19 death when a positive test result in the state system matched up with a death certificate. Under that old system, if an individual’s death was deemed COVID-19-related by a physician but the deceased did not have a positive test on file, the state did not record that as a COVID-19-related death. Under the new system, only the COVID-19 cause-of-death coding is required for the state to recognize it as a virus-related death. A matching positive test is not required any longer."
https://www.thegazette.com/subject/news/health/iowa-covid-19-deaths-reporting-change-coronavirus-20201207https://www.thegazette.com/subject/news/health/iowa-covid-19-deaths-reporting-change-coronavirus-20201207> (12/2020)


As of Dec 7, 2020 - The new methodology is based on the CDC’s National Center for Health Statistics (NCHS) cause-of-death coding. Under this new methodology, a case must be coded by NCHS with the International Classification of Diseases, 10th Revision (ICD-10) code U07.1 as the underlying cause of death or a contributing factor to death. Coding is based on the registered death record completed by the health care provider.
This methodology does not require a positive PCR or antigen test result. Deaths will be counted as a COVID-19 death if NCHS codes the death record with code U07.1 as the underlying cause of or contributing factor to death. This methodology does ensure the number of COVID-19 deaths reported will match the official state vital statistics report, when eventually published, and will provide greater consistency between the number of deaths reported by federal, state and county government agencies.

Confirmed cases include the clinical criteria and laboratory criteria. Clinical criteria refers to the presence of COVID-19 related symptoms, as listed by their site. Laboratory criteria refers to the detection of SARS-CoV-2 RNA in a clinical or autopsy specimen using a molecular amplification test. Presumptive laboratory evidence refers to the detection of SARS-CoV-2 by antigen test in a clinical specimen. There is supportive laboratory evidence as well. They are the detection of specific antibody in serum, plasma, or whole blood, or the detection of specific antigen by immunocytochemistry in an autopsy specimen. Epidemiological evidence refers to close contact with a confirmed/probable case of COVID-19 in 14 days before onset of symptoms OR indicated to belonging to a known/suspected outbreak of COVID-19. Confirmed cases meet laboratory evidence.

Confirmed case meets confirmatory laboratory evidence. Clinical criteria refer to the presence of COVID-19 related symptoms, as listed by their site. Laboratory criteria refers to the detection of SARS-CoV-2 RNA in a clinical or autopsy specimen using a molecular amplification test. A new case should only be counted based on the presence of SARS-CoV-2 RNA or detection of SARS-CoV-2 antigen and should only be counted if it is more than 3 months after the original positive specimen was collected (or at least 3 months after prior symptom onset if there was no prior positive specimen).

If a lab report has not been received, but a positive lab result has been reported verbally by a healthcare provider or by an electronic case report that clearly identifies a positive lab result, the case will be considered confirmed.
Note: If the electronic case report does not clearly identify a lab result, consider the person a Suspect case with a Pending Test.

If a presumptive case tests positive for COVID-19, update the case’s status to confirmed. If a presumptive case is tested for COVID-19 and tests negative, the case remains presumptive.

Includes cases confirmed by diagnostic testing and presumptive cases. Presumptive cases are people without a positive diagnostic test who have COVID-19-like symptoms and close contact with a laboratory confirmed case. Antibody test results are not included in our data.

A confirmed case is someone who tests positive using an FDA Emergency Use Authorized (EUA) diagnostic test. Any positive result from an RT-PCR, NAAT, or antigen platform developed under an FDA EUA, even if conducted as asymptomatic screening, is considered a positive result. A follow-up test which is negative does not negate the first positive test. If a lab report has not been received, but a positive lab result has been reported verbally by a healthcare provider or by an electronic case report (eCR) that clearly identifies a positive lab result, the case will be considered confirmed.
Death (community): death of a confirmed or probable COVID-19 case within 60 days of the earliest available date among exposure to a confirmed case, onset of symptoms, or date of specimen collection for the first positive test; or someone with a COVID-19-specific ICD-10 code listed as a primary or contributing cause of death on a death certificate.

For hospitalized: death from any cause in a hospitalized person during admission or in the 60 days following discharge AND a COVID-19 positive laboratory diagnostic test at any time since 14 days prior to hospitalization.

A confirmed death is an individual who tests positive using any diagnostic tests (as mentioned in the confirmed cases section) and has a COVID-19-specific ICD-10 code listed as a primary or contributing cause of death on a death certificate.
A presumptive case a person without a positive COVID-19 RT-PCR, NAAT, or antigen test result, with: a) An acute illness featuring at least two of the following: shortness of breath, cough, fever, new loss of smell or taste, radiographic evidence of viral pneumonia; No more likely alternative diagnosis; AND Within the 14 days before illness onset, lived in the same household or congregate setting, had close contact with a confirmed case, or is identified as having been exposed in an outbreak.A probable death is an individual who falls under the criteria of probable cases, but has a COVID-19-specific ICD-10 code listed as a primary or contributing cause of death on a death certificate.Residents YesNot applicable. Notice on 8/16: "Due to a script error some negative test results from early in the day Saturday were reported on Saturday. That may result in an unusually low positive test rate Saturday and a higher one today. This did not affect positive cases."NoneOregon publishes the total number of caes in each county, as well as the number of individuals returning a positive test associated with that county. We are entering the number of positive tests under the "confirmed cases" column, and assuming that the difference between these two figures is the number of probable cases.

Oregon does not publish the number of positive tests on Saturday and Sunday, and only publish total cases. We have been assuming that all new cases coming in on the weekend are confirmed cases.

Oregon publishes the date of death for residents. We have been including these individuals from the date of their death, rather than the date that their death was reported.

Oregon publishes the statewide total number of cases by date of diagnosis. We have been adding cases to an "Unknown County" on historic dates in order to match these figures. All cases entered this way have been added to the confirmed case column.

Daily data entry continues but as of July 2021 monthly data bursts are done for unknowns.

WashingtonResidence, those that do not yet have an assigned county are placed into an "unknown" category.

WA reports resident data, and notes the number of cases that have not been assigned to a county on bottom of interactive dashboard. Historical data in dashboard. Data spreadsheet reports cases and deaths by week of illness onset, county (location), and age. (10/21/20)
Confirmed cases are reported for those who have had a positive molecular test for COVID-19

confirmed cases are when cases are tested positive using the viral PCR test, which is administered as a primary diagnostic test (positive PCR test means testing positive on the PCR test regardless of antigen status). Positive antigen tests are not included in the DOH dashboard. The state also uses antigen tests (though it is less common) and includes antigen-positive COVID-19 cases in state data (antigen-positive meaning that an individual tested positive for antigen test in absence of PCR test), with data reporting these results starting from 6/15/2020. This is included in a separate weekly report, and is currently under review by public health experts to determine how this will factor in reporting of cases. WA DOH reports that “the true number of people who have been infected with COVID-19 in Washington greatly exceeds the number of COVID-19 infections that have been laboratory-confirmed”, implying that there is underreporting of confirmed cases by the state. The state reports positive confirmed cases on the day of an individual's initial positive test result, and not from when it was reported to DOH (changed on 6/16/2020). State only reports confirmed cases of an individual once (initial positive result). .
Deaths are reported for those who have had a positive molecular test for COVID-19.

Reporting deaths of individuals that have tested positive for COVID-19. Confirmed deaths take a little longer for it to be reflected in the state’s data because oftentimes the deaths are reported to local departments, and then to the state DOH. In addition, the state began to remove deaths on 6/17/2020 from daily counts where COVID-19 did not cause or contribute to an individual's death.
State DOH does not report probable cases in dashboard, all cases reported are confirmed cases. But a probable case as defined by WA is when “(interim until CSTE case classification is finalized) - compatible clinical syndrome AND epidemiologic link to a laboratory positive case with no confirmatory test result; OR Positive antigen; OR Death certificate includes “COVID-19” or “SARS-CoV-2” with no confirmatory test result”. State DOH does not report probable deaths in dashboard, all cases reported are confirmed deaths (individuals who have deceased with COVID-19 being the cause or contributing to their death). However, WA has expanded their classifications regarding COVID-19 death cases (see below).
COVID-19 contributed to the death (death certificate, testing, and other case information available to confirm);
COVID-19 probably contributed to the death (death certificate information available but testing information not available);
COVID-19 is suspected to have contributed to death (follow-up being conducted prior to ruling out or confirming death); or
COVID-19 did not contribute to the death (examples include homicide, overdose, suicide, car accident, or disease with clear exclusion of COVID-19 illness).

Residents YesWe have been using reports from county health departments in Benton-Franklin, Grant, and Snohomish. There is a decrease on 6/8 because Benton-Franklin ceased reporting probable cases.11/24/20: WA is on a reporting delay, next report won't be until 11/30/20Yes. Data is updated at 4:30 PM EST and reflects data as of 11:59 EST the previous day.All data was entered from the state health department.

Washington state updates their cases by date of symptom onset, and deaths by date of death. We periodically update our data to reflect this.

As of 3/29/21, Washington state doesn't report data on Sundays and sometimes doesn't report data on Saturdays.

Daily data entry was stopped on 7/10/2021 - data is now entered through a monthly data burst.

Puerto Rico ResidenceReporting both probable and confirmed cases

Probable cases are individuals who have a positive antigen test result, or are symptomatic and are epidemiologically linked to a confirmed case of COVID-19 but have not had confirmatory testing performed.

Confirmed cases are cases with a positive molecular test (RT-PCR). The number of additional confirmed cases since the last report does not imply that these cases correspond to the last 24 hours. The total may reflect adjustments for previously unreported cases with a sampling date more than 14 days prior to today's date. (recorded in QA 10/21/20)
cases of COVID-19 confirmed by RT-PCR test
Counted deaths include those who were confirmed to have COVID-19 through a lab result and then subsequently died during the course of having the disease or having complications related to the disease, and also patients whom the medical examiner deems to have died as a result of COVID-19.

Confirmed COVID-19 deaths are deaths of people with one or more positive molecular tests. The numbers reported are provisional counts and show the data available in the system at the time of reporting. The amounts will change as the processes of registration and codification of causes of death progress. When a death occurs, a certifier will complete the death certificate with the underlying cause of death and any contributing causes of death. All deaths with COVID-19 will be coded manually. Death certificates are normally manually encoded within 7 days of receipt, however the encoding delay may increase if there is a large increase in the number of deaths. As a result, the underestimation of the number of deaths may be greater for certain causes of death than for others. (recorded in QA on 10/21/20)
COVID-19 certified deaths (confirmed or probable) that have been identified in Puerto Rico
Probable cases are cases with a positive serological test. The number of additional probable cases since the last report does not imply that these cases correspond to the last 24 hours. The total may reflect adjustments for previously unreported cases with a sampling date more than 14 days prior to today's date

Probable cases are cases with a positive antigen test. The number of additional probable cases since the last report does not imply that these cases correspond to the last 24 hours. The total may reflect adjustments for previously unreported cases with a sampling date more than 14 days (11/18/20)
cases that tested positive for COVID-19 through an antigen test
Probable deaths by COVID-19 includes deaths of: 1) People who meet clinical criteria and epidemiological evidence as defined by the CSTE; 2) People with a positive serological test and who meet the clinical criteria or epidemiological evidence as defined by the CSTE; and 3) Deaths that meet the vital statistics criteria in which they were not carried out confirmatory tests for COVID-19. This is in accordance with the provisional recommendations of the Council of State and Territorial Epidemiologists ”(CSTE) and the“ National Center for Health Statistics ”of the CDC. The change in the number of deaths should not be interpreted as having occurred in the last 24 hours. Likewise, it is important to note that the total number of deaths may vary depending on whether the processes of registration and coding of causes of death, which can take several days.Residents UnknownNot applicable. Puerto Rico did not report data on May 1 or May 2, but did release reports with data for May 1, May 2, and May 3 on May 3. Yes. Data is updated at 7 AM EST and reflects the previous days data. We are currently accounting for this in our counts.Puerto Rico does not report deaths by location. We have been placing them in the "Unknown County."

On 3/07/2021, Puerto Rico's main data entry source became inaccessible and data entry transitioned to using a new historical source to input data from.

ADHawaiiBoth. Some numbers include people diagnosed in one county where they will complete quarantine despite being a resident of a separate county.

"Case location based on ZCTA of case residence or location stayed while in Hawaii."

New counties reporting method. Honolulu county on Broadstreet data is a sum of Lanai, Molokai, and Oahu counties. Hawaii DOH reports these three counties separately and Hawaii county has been eliminated from the report.
Positive cases includes presumptive and confirmed cases

The number of Daily New Cases is defined as the count of all newly diagnosed and reported cases of COVID-19 in the past 24 hours. (recorded in QA on 10/21/20)
COVID-19 should be reported on the death certificate for all decedents where the disease caused or is assumed to have caused or contributed to death. Other terminology, e.g., SARS-CoV-2, can be used as long as it is clear that it indicates the 2019 coronavirus strain, but we would prefer use of WHO’s standard terminology, e.g., COVID-19. (Recorded in QA on 10/21/20)Probable cases are individuals who have a positive antigen test result, or are symptomatic and are epidemiologically-linked to a confirmed case of COVID-19 but have not had confirmatory testing performed. Probable cases are not included in counts of confirmed cases.Includes Hawaii residents and non-residents

They reported both residents and non-residents. Positive cases include confirmed cases, and Hawaii residents and non-residents; data are preliminary and subject to change. Note that CDC provides case counts according to states of residence. Historical data on dashboard and on wayback machine.
YesNot applicable. 11/15: Hawaii experienced a data reporting lag, they didn't update their website so 11/14 and 11/15 data match.NoneAll data was reported from the state health department.
Hawaii residents that were out of state were entered into the "Unknown" County.

We began including probable cases reported by Hawai'i on 9/09/20. Probable cases are updated once weekly.

AlaskaResidenceThe cases included on the data dashboard include both confirmed cases diagnosed by an RNA detection test. Cases for Alaska are defined in accordance with national standards in the CDC Case Definition. https://wwwn.cdc.gov/nndss/conditions/coronavirus-disease-2019-covid-19/casedefinition/2020/08/05/ (recorded in QA on 10/21/20)Counted deaths include 1) those who were confirmed to have COVID-19 through a lab result and then subsequently died during the course of having the disease or having complications related to the disease, and also 2) decedents on whom the medical examiner conducts a death investigation which results in a positive COVID lab test.

Counted deaths include deaths where the medical professional outlines COVID-19 as a part of the logical sequence of causes, or etiology, that led to death. Out-of-state deaths of confirmed cases of Alaska residents are reported by another state either directly to the Section of Epidemiology or collected by the Section of Health Analytics and Vital Records through the State and Territorial Exchange of Vital Events system. The process of confirming and reporting deaths can take several weeks, therefore deaths do not reflect real-time reporting due to the reporting lag time. The “Cumulative Deaths” graph reflects the date when a death was confirmed by the State, not when the death occurred. (recorded in QA on 10/21/20)
probable cases not reported.probable cases not reported.A callout box was added to the dashboard on 4/21/20 that lists an approximate cumulative total for the number of cases diagnosed in Alaska in non-residents. These cases will be listed in the callout box only, and not included in any of the raw data sets or other graphics, which are all limited to confirmed Alaskan-resident cases only.

The data displayed on the Data Hub as of August 4th can be shown by Alaska residents (including AK residents diagnosed and isolated OOS), by non-residents, or by both residents and non-residents diagnosed and isolated in Alaska. To view data by AK residents, select “All” under the Occurrence filter and “Resident” under the Residency filter. Historical data available in csv files (excel sheets) (10/21/20)
NoNot applicable. NoneOn 6/24/20, Alaska began reporting non-resident cases with resident cases. We began including the non-residents in local totals


Alaska has removed one of their counties (Valdez Cordova) and has added two new ones instead, we will be taking the sum of those two new counties and placing them in the Valdez Cordova row for now. (2/17/21)

On 3/29/21, Alaska stopped reporting data on weekends and sometimes doesn't report data on sporadic Mondays.

On 4/14/21, Alaska has reverted to reporting data on every weekday.

As of 7/26/2021 Alaska is only reporting data Monday, Wednesday, and Friday.

AECaliforniaBoth. Alpine, Colusa, Del Norte, Glenn, Inyo, Lake, Lassen, Madera, Mariposa, Modoc, San Benito, Shasta, Sierra, Siskiyou, Sutter, Tehama, Trinity, Tuolumne, and Yuba do not report cases by locality, but the rest of the counties do. Number of new lab-confirmed positive COVID-19 cases reported by local health departments each day. Laboratory criteria refers to the detection of SARS-CoV-2 RNA in a clinical or autopsy specimen using a molecular amplification test. (1/2021)Number of new COVID-19 related deaths reported by local health departments to each day. This determination is made by local health departments based on the cause of death reported on death certificates. It is expected that, to be counted, COVID is the cause of death or at least a contributing factor to the death. (1/2021)Probable cases are not reported (1/2021)Probable deaths are not reported (1/2021)Not specified. UnknownThe LA Times updates for the final time per day at around 10 pm EST. This means that the data for California will not be entered until late at night or early the following morning. Quest Diagnostis did not report between 7/31-8/4

California repeatedly reported issues with backlogs with the California Reportable Disease Information Eschange in July and August
Accordning to The LA Times, "Local governments announce new cases and deaths each day, though bottlenecks in testing and reporting lags can introduce delays. For instance, some agencies do not report new totals on weekends, leading to lower numbers on those days."Used data reported by the LA Times in California. LA Times collected data from individual county health departments across California.

Data entry was automated as of 7/11/2021.
