Summary

Background:

In early 2020, many people thought Cambodia would have a serious COVID-19 outbreak due to the high number of Chinese travelers going to Cambodia. But as of June 14, 2020, only 128 cases of COVID-19 have been identified in the country. Many of these cases have been from people who had traveled in Europe. Researchers want to do antibody tests on blood from a sampling of people in Phnom Penh to learn the infection risks for people in the greater Phnom Penh area.

Objective:

To estimate the level of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the blood of people living in Phnom Penh, Cambodia.

Eligibility:

Healthy males and females age 18-65 living in Phnom Penh since January 2020.

Design:

A mobile unit will travel to schools, shopping areas, parks, and pagodas around Phnom Penh.

Participants will be screened with questions about their age and where they live. They will have blood taken via fingerstick. About 80 uL of blood will be taken. It will be tested for SARS-CoV-2. This visit will take about 30 minutes.

If the test result is positive, participants will be contacted by phone. They will be asked to have a second blood draw. This time, 20 mL of blood will be taken. They can have this visit at their home or in a clinic. This visit will take about 30 minutes.

If a participant has an adverse event, the mobile units and at-home units will have the tools needed to aid the participant. If needed, the participant will be sent to a nearby clinic.
