Reinfection may be possible.
If a person gets COVID-19, are they immune to future infection from SARS-CoV-2? And how long will immunity last? Ten to 30% of our common colds are caused by four different coronaviruses, and we all know that having a cold doesn’t keep you from catching another cold.
Across several countries, doctors have confirmed less than a 100 cases of SARS-CoV-2 reinfection. The risk of reinfection with SARS-CoV-2 varies from person to person and also depends on the specific strain, or variant of SARS-CoV-2 the person is exposed to. In general, natural immunity and protection from reinfection is thought to last 6 to 12 months, but some people were reinfected earlier.
