Woman gets Covid twice in 20 days, with 2 different variants: shortest re-infection gap. Watch details

The woman in Spain caught Covid just 12 days after getting a vaccine booster shot; and the second infection followed less than 3 weeks later.

A woman in Spain caught Covid twice, within 20 days, and with different variants. This is being pegged as the shortest re-infection gap recorded since the beginning of the Covid-19 pandemic.

The patient is a healthcare worker, who was fully vaccinated, and had even received a booster dose. Just 12 days after the booster vaccine, on December 20, 2021, the woman tested positive during a staff screening test. She went into isolation for 10 days, but did not develop any symptoms.

Then, on January 10, 2022, twenty days after the first infection, she developed Covid-like symptoms and took another RT-PCR test.
The result again came out to be positive.

When the samples were sent for genome sequencing, it emerged that the woman had been infected by two different variants of the Sars-CoV-2 virus. The first, symptom-less infection was with the Delta variant, while the second one was Omicron, with cough and fever.

Scientists said that this case shows how Omicron can evade immunity from both vaccines and previous infections.
