At the onset of infections, re-infection with COVID appears to be very rare, but the portrait has changed significantly with the rise of the Omicron variant.

The 31-year-old Spanish health worker caught COVID twice in 20 days, the shortest case of documented relapse, Spanish researchers have found.
Experiments show that the woman is affected by two different types of govt: by delta in late December and by Omigron in January.
According to researchers, the BBC reports that this example shows that someone who has been infected or vaccinated against Govt has no immunity.
In the UK, officials are demanding that the 90-day period between two positive tests be considered relapsed.
Based on this definition, health officials estimate that by April 2022, approximately 900,000 people could be infected again.
Spaniard developed no symptoms after her first positive PCR test, but developed a cough and fever within three weeks, prompting her to take another test.
Upon further analysis of the tests showed that the patient was infected with two different types of corona virus.
In a presentation to the European Congress on Clinical Microbiology and Infectious Diseases, the study’s author, Dr. Gemma Recio, said that Omigron had proven that “natural infections or vaccines can prevent previously acquired immunity.”
In other words, people infected with Govt-19, even if fully vaccinated, cannot be considered safe from re-infection.
“However, those with previous infections and the vaccine Omicron appear to be somewhat safer from serious illness and hospitalization, among other variants,” the doctor added.
COVID re-infections increased sharply in December 2021 after the appearance of the highly contagious Omigran variant, and due to BA.2, which was released in early March.
Prior to Omicron, 1% of all cases registered in the UK were labeled as secondary infections – but that number has now risen to 11%.
Most may be affected by alpha or delta types and then re-infected by the highly contagious Omigran.
Scientists estimate that everyone will eventually catch Govt twice, and may have multiple in their lifetime.
