Brief Summary

Our current focus is to reduce the spread of COVID through distribution of Rapid Antigen Test Kits (ATKs) to low-income, high-risk communities across Bangkok. Hospitals across Thailand have been operating over capacity for many months, both in receiving the high number of cases as well as in testing for COVID. RT PCR, although highly sensitive, requires potentially infectious people to travel to testing sites, wait in line, and takes 1-2 days to return results, leading to further spread of COVID through increased contact with other high-risk individuals. On the contrary, testing via an Antigen Test Kit (ATK) can be done by everyone at home with the potential to test more frequently than the PCR test due to much cheaper cost. This means that ATK testing can be mixed into people's daily lifestyle, but another underlying reason is that ATKs only show test results as positive only when an infected person is contagious. Another key advantage is the rapid results, which helps people identify risks quickly, limiting spread even faster. Our trial therefore aims to achieve the following primary objective: To monitor the results of freely distribute ATKs in real environments to measure its effectiveness in reducing COVID spread in communities by comparing the incidence of COVID-19 between communities with rapid antigen tests and without rapid antigen tests. Secondary objectives are:

  1. 1.To compare the incidence of severe COVID-19 between communities with rapid antigen tests and without rapid antigen tests.
  2. 2.To study the decrease in incidence of community-acquired COVID-19 in communities with rapid antigen tests.
  3. 3.To study factors affecting community-acquired COVID-19 in these communities.
  4. 4.To campaign for the government to recognize the importance and effectiveness of weekly testing, and propose suitable strategies to fight COVID.
