Plain English summary of protocol

Background and study aims
The World Health Organization (WHO) has released guidelines supporting the use of rapid antigen tests for diagnosing SARS-CoV-2, including self-testing. These tests are commonly used in wealthy countries. However, the policies and practices regarding the use of antigen rapid diagnostic tests (Ag-RDTs) are not well-defined in most African countries, including Malawi. It is important to incorporate affordable rapid testing into regular healthcare services in order to promptly diagnose individuals at high risk of COVID-19 and make them eligible for oral antiviral treatments. While self-testing strategies using Ag-RDTs are already implemented in many COVID-19 testing approaches funded by governments in wealthy countries, self-test kits that can be purchased over the counter are not yet supported by policies in low- and middle-income countries for COVID-19 self-testing.

In this study, we aim to compare the number of confirmed COVID-19 cases diagnosed within five days of experiencing symptoms between two groups: one group receiving twice-weekly COVID-19 self-test kits and the other group receiving the standard of care. The standard of care includes considering the number of days off work due to suspected or confirmed COVID-19. All positive results from the COVID-19 self-tests will then undergo confirmation through polymerase chain reaction (PCR) testing and/or testing by a provider using Ag-RDTs (standard of care group). The goal is to detect infections early and enable effective infection prevention and care.

Who can participate?
Health care workers (HCWs) in Blantyre District i.e. both urban and rural public primary health centres. There will be six intervention health facilities under and six facilities under the standard of care arm.

What does the study involve?
For this study, we will conduct a controlled study with two groups, but the assignment to each group will not be random. In the standard of care group, we expect an average count of 20 and 35 confirmed cases of COVID-19 diagnosed within three months, with a standard deviation of 12. In the intervention group, the confirmed cases will be determined either by PCR testing or by repeating the antigen rapid diagnostic test (Ag-RDT) with the help of a professional. There will be a total of six clusters in each group, and each cluster will consist of 100 healthcare workers (HCWs).

What are the possible benefits and risks of participating?
-Potential direct benefits to you for participation in the study include easy access to COVID 19 testing, early detection COVID, and prevention of spread to high risk individuals you closely associate with.
-During participation in this study you may experience discomfort in your nose as the nasal swab is inserted. It is expected that this discomfort will go away soon after sample collection. If correct sampling technique is followed, the risk of complications from the procedure is low. Though rare, expected complications may be nasal bleeding or broken swab if excess pressure was applied. If you experience any of these problems, please report to study staff and you will be referred for appropriate treatment.
-You may also obtain a positive COVID-19 from your self-test, which may worry you. The researcher will discuss the meaning of the results with you and refer you to the national COVID-19 program where you will get help.
-On a more unlikely note, although we will conduct the study activities in private, it is possible that some people may know of your study participation and assume that you have COVID-19. This may affect your social or business relationships.
