Community surveillance of COVID-19 by village health volunteers, Thailand.

Problem: To control the increasing spread of coronavirus disease 2019 (COVID-19), the government of Thailand enforced the closure of public and business areas in Bangkok on 22 March 2020. As a result, large numbers of unemployed workers returned to their hometowns during April 2020, increasing the risk of spreading the virus across the entire country.

Approach: In anticipation of the large-scale movement of unemployed workers, the Thai government trained existing village health volunteers to recognize the symptoms of COVID-19 and educate members of their communities.
