While every person will have different immunity levels, it is possible you could get reinfected with Omicron about three months after catching the original strain. But what happens now? The reason for this, Maniar says, is that a PCR test can still detect trace amounts of the virus even after someone is no longer symptomatic or infectious.

Therefore, it's highly unlikely that a person has caught it twice and been confirmed by laboratory testing. While data is still limited around Omicron spread given that researchers need more time to confirm trends, real-world data of Omicron spread in South Africa suggests that overall immunity may be less robust following a mild COVID-19 infection, which has been the case for most Omicron sicknesses, says Sanjiv S.

These include: Certain factors can affect the severity and duration of the Omicron variant, such as underlying health conditions, age, and history of prior infection.

Research has shown that for people who recover from COVID-19, immunity can last for about three months to several years, so it is unlikely you will get two different infections of COVID-19 within 90 days. Gluckstein explained this is why Omicron caused a dramatic wave of recent infections, but a less dramatic increase in severe disease and death than earlier COVID-19 variant strains. The window largely associated with earned immunity tends to be closely associated with current guidelines published by the Centers for Disease Control and Prevention (CDC), which maintains that those who have tested positive for COVID-19 shouldn't test again for another 90 days.
