3. What is the probability of a COVID-19 reinfection?

The probability of a COVID-19 reinfection is primarily related to one's immunity level and variation in the newly contacted virus strain.

When a person comes into contact with a new strain of the COVID-19 virus, the higher the antibody and other immune reaction indicators, the less the virus strain varies from strains encountered during previous inflections, and the lower the probability of reinfection.
