She was infected with COVID-19 twice in less than 20 days

At the beginning of the epidemic, while cases of re-infection with Kovid‌ were rarely seen, the portrait changed significantly with the rise of the Omicron variant.

The 31-year-old Spanish healthcare worker caught Kovid twice in 20 days, with the lowest case of reinfection recorded by Spanish researchers.

Tests showed the woman was infected with two different variants of Kovid: by Delta in late December and by Omicron in January.

According to researchers, the BBC reports that this example does not necessarily mean that a person infected with Kovid or vaccinated will be immunized.

In the United Kingdom, authorities must consider a 90-day period between two positive tests as re-infection.

Based on this definition, health officials say that by April 2022, nearly 900,000 people are likely to be infected again.

Spaniard did not develop any symptoms after her first positive PCR test, but developed cough and fever in less than three weeks, prompting her to do another test.

When the tests were analyzed in more detail, they showed that the patient was infected with two different types of coronavirus.

In a presentation to the European Congress of Clinical Microbiology and Infectious Diseases, the study’s author, Dr. Gemma Recio, said the case “demonstrated that Omicron could” avoid pre-existing immunity to natural infections or vaccines with other variants. “

In other words, even if people with Kovid-19 are fully vaccinated, they cannot be expected to be protected from re-infection.

“However, pre-infection and vaccination with other variants can partially protect those with omicran from serious illness and hospitalization,” the doctor added.

Kovid re-infections increased significantly after the emergence of the highly contagious Omicron variant in December 2021, as well as BA.2, which emerged 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 infected with alpha or delta variants and re-infected with the more infectious Omicron.

Scientists expect everyone to eventually catch COVID twice and many times in their lifetime.
