Spanish Woman Gets COVID Twice in Just 20 Days

Spanish researchers revealed a healthcare worker tested positive for the Omicron strain of the coronavirus barely 20 days after contracting an infection caused by the delta variant.

The case of the healthcare worker is yet to be presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Lisbon, Portugal scheduled for April 23-26.

ECCMID, in a news release, said the 20-day gap between infections is the shortest known.

The 31-year-old woman, who was fully vaccinated and boosted, first tested positive on December 20, 2021, in a PCR test during staff screening at her workplace. 

“Whole genome sequencing showed that patient had been infected by two different strains of SARS-CoV-2. Their first infection, in December, was with the Delta variant. The second, in January, was with the Omicron variant,” a portion of the news release read. 

Dr. Gemma Recio of the Institut Català de Salut in Tarragona, Spain, one of the study’s authors, said the case “underlines the ability of the Omicron variant to elude previous immunity gained either from natural infection with other variants or from vaccines”.

“In other words, people who have had COVID-19 cannot assume they are protected against reinfection, even if they have been fully vaccinated. Nevertheless, both previous infection with other variants and vaccination do seem to partially protect against severe disease and hospitalization in those with Omicron,” Recio added.

The congress selection committee has peer-evaluated the material. 

However, there is no full paper available while the authors have not yet submitted their work for publication in a medical journal.
