Therefore, it is crucial that you get COVID-19 boosters to protect yourself against other variants. In most cases, people get a covid test positive for 90 days after the first infection. However, genomic sequencing has shown that people can get COVID twice within 90 days. A study done showed that numerous people had been infected with two variants of COVID within 90 days of the initial infection.

Are Reinfections Dangerous?

According to the CDC, those who recover from COVID-19 still have some protection against COVID-19 reinfections because of the antibodies they produce while they have the health condition. However, further infections may cause unanticipated health issues.

5.4 million patients were the focus of an initial study conducted by researchers at Washington University in St. Louis. When there were two or more cases of COVID-19 in a patient, the risk of cardiovascular problems, including mortality, was shown to be increased by 100%. 

People who were infected a second time had an increased risk of complications in their kidneys, lungs, and digestive systems.

  • Take an antigen test (such as a quick home test) at least five days after exposure if it has been over 30 days since your previous illness.
  • If it's been longer than a 90-day period after your previous infection, you should take an antigen or test five days after exposure.
  • You should stay at home in isolation and get checked out if you start experiencing symptoms after a recent exposure. Ensure not to use an inconclusive lateral flow test. Hence, you should opt for a Healgen test kit or a FlowFlex antigen test
  • Isolate yourself at home for five full days if you have tested positive for COVID-19 with an antigen test or if your doctor has diagnosed you with COVID-19 reinfection and it has been 31-90 days since your last infection (with the first day being the day your symptoms started or the day you were tested without symptoms). After you've ended the isolation, you should keep your isolation mask on until day 10.
