2. How to determine COVID-19 reinfection?

Different countries or regions have different definitions of the COVID-19 reinfection, but the basic condition is to have a period of time pass between the first and second infection. The interval is defined as at least 90 days in the UK, and 60-90 days or more in the United States.

COVID-19 reinfection is comprehensively determined by considering symptoms, clinical manifestations, immune responses, and other indicators.
