On May 22, 2024, the Yogyakarta Municipal Health Office received a report of seven children with swollen cheeks and fever at two kindergartens from Mantrijeron Health Center.

​

INTRODUCTION

• Descriptive study to describe attack rate by demographic, symptoms, treatment, and risk factors. Period: May to June 2024.
• Active case finding; Interviews and administered online self-assessment questionnaires to school residents and parents on demographic, symptoms, onset date, treatment, and risk factors.
• Environmental observation to look for potential risk factors in people and school buildings.

This investigation aimed to describe mumps outbreak characteristics and risk factors and recommend control measures.

Objectives:

METHODS

School residents from Kindergarten R and S who had swollen cheeks and fever with one or more the following symptoms: odynophagia, loss of appetite, malaise, headache, stomach ache, and myalgia from May to June 2024.

• Contact with cases,
• High population density in class,
• Poor ventilations,
• Less awareness of disease transmission and prevention (including mumps vaccination) among school residents and parents.
• Inter-school transmission was likely to occur because they shared the same field during sports lessons.

Outbreak risk factors:

CONTROL MEASURES

• Temporary dismissed school activities, and self-isolate cases.
• Disinfecting classrooms.
• Wearing masks.
• Giving information to school residents about mumps, and educate about hygiene and healthy living behavior (i.e. sneezing etiquette, washing hands with soap)

Discussion

Introduction

Moch. Thoriq Assegaf A, Shabrina Riskya Madjid, Hendrika Yuniartin Ganis, Nyai Harifah Akbar, Annisa Utami Rauf

• Climate-sensitive Infectious Disease issue 🡪 hazard potential for disease dynamic
• Fluctuated trend of dengue in Sleman
• Effort to achieve national target for IR and CFR
• Risk mapping with temporal approach could be support the optimalization of response and intervention

​

Scan for the futher references

• Enlarge of coverage and behavior of vector control
• positive response of Wolbachia could maintenance the behavior of vector control
• Effect of climate-change descriptively impacted to dengue trend with lagging 1-3 month
• Optimum period for intervention: July-October
• Peak of dengue: March-May

Method

• Cross sectional descriptive with 81 respondent in Sleman (convenience sampling)
• Temporal mapping focuses on hazard and vulnerability of dengue, refers to STAR guideline from WHO (2021)

• 61% of respondents engaged in at least 2 vector control behaviors each week in the past 3 months.

• respondents showed trust and positive perceptions towards Wolbachia.
• 88% of respondents stated that they would continue to carry out PSN/3M Plus even though Wolbachia was present.
