A 31-year-old lady contracted COVID-19 two times within three weeks, in spite of being fully vaccinated and getting a booster shot just 12 days earlier. Whole genome sequencing revealed that the first infection was the Delta version and the second infection 20 days later was with the Omicron variant.
A fully vaccinated and boosted 31-year-old lady checked positive for Omicron strain of SARS-CoV-2 simply 20 days after having Delta infection.
Researchers in Spain offer details of a 31-year-old female who contracted COVID-19 twice within three weeks, in a case report that will be presented at this years European Congress of Clinical Microbiology & & Infectious Diseases (ECCMID) in Lisbon, Portugal on April 23-26.
The 20-day period in between infections is the shortest ever tape-recorded
The woman, a health care employee, first tested favorable in a PCR test during staff screening at her workplace on December 20, 2021..
She was totally immunized and had received a booster shot 12 days previously.
The client, who didnt develop any symptoms, self-isolated for 10 days prior to returning to work.
On January 10, 2022, just 20 days after very first screening favorable, she established a cough, and fever and felt normally weak and did another PCR test. This was likewise positive.
Entire genome sequencing showed that patient had been infected by two various stress of SARS-CoV-2. Their very first infection, in December, was with the Delta version. The second, in January, was with the Omicron variant.
The Omicron variant had been determined as a variant of issue by the World Health Organisation just over a month earlier, on November 26, 2021.
The strain, which went on to become the dominant variation internationally, is far more infectious than Delta and can averting resistance from previous infections along with vaccination.
Dr. Gemma Recio, of Institut Català de Salut, Tarragona, Spain, among the studys authors, states: “This case highlights the potential of the Omicron version to avert the previous resistance got either from a natural infection with other variations or from vaccines.
” In other words, people who have actually had COVID-19 can not presume they are secured versus reinfection, even if they have been totally immunized.
” Nevertheless, both previous infection with other versions and vaccination do appear to partly protect against extreme disease and hospitalization in those with Omicron.
” This case likewise underscores the need to perform genomic surveillance of viruses in infections in those who are completely immunized and in reinfections. Such tracking will help find variations with the ability to partially evade the immune action.”.
