Map of California COVID-19 Cases

Implications of COVID-19

  • Countries worldwide have implemented travel restrictions, curfews, quarantines, and stay-at-home orders. Many countries are also working to increase testing capacity and trace contacts of infected individuals.
  • Severe global socioeconomic disruption, including the largest global recession since the Great Depression.
  • Cancellations of religious gatherings, political and cultural events, and sporting events, among others.
  • Universities and schools have closed around the world, affecting around 98.4 percent of the global student population.
  • Misinformation about the virus has been spread online and there have been numerous xenophobic and discrimination incidents around the world, primarily targeting Chinese people and against those who are perceived to be Chinese.
  • In California, a state of emergency was declared on March 4th, followed by a stay-at-home order given on March 19th. The stay-at-home order in California is still on-going. As of April 26th, there are 42,164 cases of COVID-19 in the state.

Discussion and looking forward

Data collection will continue, with the map being updated as new data comes in. For next steps, more data will be collected on COVID-19 patients, including those who have been tested and suspected cases. Unfortunately, the data for “positive COVID-19 patients” and “positive COVID-19 ICU patients” is not mutually-exclusive, meaning we cannot predict the ratio of people per county who will need ICU-level care. Therefore, mutually-exclusive data for COVID-19 ICU patients will be explored. How many people have been tested per county will be investigated, as well as each counties’ testing capabilities.

Data on the number of ventilators per county will also be investigated to calculate the ratio of ventilators to people in each county. Data on the race, gender, and age for COVID-19 patients would be helpful to find other possible correlations and to further map out and understand COVID-19 in California.

Mapping COVID-19 in California

What is COVID-19?

  • COVID-19 is an infectious disease caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2). First identified in December 2019 in Wuhan, China, the disease has since spread globally, resulting in a global pandemic.
  • The virus is primarily spread between people during close contact, often via small droplets that are produced from sneezing, coughing, or even talking.
  • Common symptoms can range from shortness of breath and fever, to the more severe symptoms of acute respiratory distress syndrome (ARDS) and pneumonia.
  • Currently there is no known vaccine, or any specific treatment and primary treatment is supportive therapy and care.
  • The recommended preventative measures include covering one’s mouth when coughing, washing hands, wearing masks when outside, physical distancing, and self-isolation and monitoring for people who are suspected of being sick.

Using data collected from CalMatters over a one-month period, I created this map of each county’s COVID-19 statistics. This map was created using Tableau, a data visualization software. Using this software, I made the map interactive, where the user can use their cursor to search each county for these statistics. I computed the statistics for each county, those statistics being: positive COVID-19 cases, positive COVID-19 ICU patients, population, etc. I created the map using a blue spectrum gradient, meaning the darker the blue, the more COVID-19 cases are present.

Looking at the map, Los Angeles County has the highest number of COVID-19 patients in California. This could be explained by Los Angeles County having the largest population in California (over 10 million). There are also entire counties that, as of April 20th, appear to have zero COVID-19 cases, such as Del Norte and Modoc. Like Los Angeles County, this could be attributed to population, as both counties have a small population (27, 812 and 8,841 respectively).
