A Spanish health worker is the person who has taken the shortest time to be reinfected with covid-19 in the world, according to a report presented at the European Congress of Clinical Microbiology and Infectious Diseases (ECCMID).
The 31-year-old woman, who had the full Pfizer regimen and a booster dose of Moderna 12 days before the second positive, caught the delta variant and only 20 days later, she did it again, but this time, with omicron. The first time, a few days before Christmas 2021, she was asymptomatic and the second time, already in January 2022, she had a cough, fever and general malaise. Until now, the fastest reinfections were 30 days.
“This case shows the omicron potential to evade previously acquired immunity, either by natural infection with other variants or by vaccines,” says Gemma Recio, a researcher at the Catalan Institute of Health in Tarragona.
Until March 30 (latest available report), the Carlos III Institute had recorded 161,441 reinfections by covid-19 in Spain, although only 1,993 (1.2%) had been confirmed. In any case, the actual number of reinfections is much higher.
