Introduction

SARS-CoV-2 antigen rapid diagnostic tests (Ag-RDT) are being used globally to test suspect COVID-19 cases in contexts where PCR diagnostic may not be available, often at subnational level.   

COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main symptoms including manifestations include fever, fatigue and dry cough, nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.

Individual factors can contribute to SARS-CoV-2 transmission

● People infected with SARS-CoV-2 can transmit virus with or without symptoms

● Most infected people transmit the virus around 2 days before they develop symptoms and up to 9-10 days after symptom onset

● People who develop severe disease can be infectious for longer

● Immunocompromised people can shed the virus for months

● Symptomatic persons infected with SARS-CoV-2 are 3 to 18 times more likely to transmit the virus than asymptomatic persons.
