COVID-19 reinfection
19 August 2022
There is a small risk of reinfection with COVID-19 within 4 weeks of having COVID-19 but it is unlikely, unless you are immunocompromised.
If you get new symptoms within 4 weeks of initial infection, stay home while sick.
People at greater risk of severe COVID-19 disease who develop new symptoms within 4 weeks of ending isolation should contact their GP or healthcare provider for advice.
WA’s Deputy Chief Health Officer, Dr Clare Huppatz, outlines what to do if you get symptoms within 4 weeks of COVID-19 infection (external site).
People who get new COVID-19 symptoms more than 4 weeks after ending isolation should get tested with a rapid antigen test (RAT) or PCR.
If the test result is negative, stay at home until symptoms resolve.
If the test is positive for COVID-19, follow the isolation protocols for a case.
