Covid: A woman was infected with two variants in a record 20 days

Spanish researchers say a healthcare worker in Spain has been diagnosed with Covid twice in 20 days, the shortest known gap between infections.

The 31-year-old woman was infected with two different variants, Delta in late December and Omicron in January.

The health worker did not develop any symptoms after his first positive PCR test in December.

However, within a few weeks he developed a cough and fever and underwent another test which again showed a positive.

Analysis of the tests showed that the patient was infected with two different variants of the virus.

Presenting the European Congress on Clinical Microbiology and Infectious Diseases, the study’s author, Dr Gemma Recio, said the case emphasized that Omicron could “avoid previous immunity acquired through natural infection with other options or vaccines”.

Dr. Recio, from the Catala de Salute Institute in Tarragona, Spain, said: “In other words, the people who had COVID-19 One cannot assume that they are protected from re-infection, even if they have been fully vaccinated.

“Nevertheless, the previous infection with other variants and vaccination seems to partially protect against serious illness and hospitalization of omicron patients.”

The study author also said it was important to monitor re-infections in people who had been fully vaccinated.

Re-infection in the UK requires 90 days between positive tests.

Health officials say nearly 900,000 people have been potentially infected twice with Covid by early April. However, it is difficult to determine the exact number because not all positive tests pass through the entire genome sequence needed to test for infections from different strains.

According to the UK Government, 174,982 people a week had a positive test result as of April 20. This is a 31 percent decrease compared to the previous seven days.

However, these results reflect how many people have the virus so unaware that free lateral flow tests were scrapped earlier this month as part of the government’s plan to live with Kovid.

Covid re-infections increased in December 2021 after the emergence of the much more infectious Omicron variant. Another increase in infections was observed in March when a slightly different version of Omicron appeared, called BA.2.
