A healthcare employee caught Covid on two separate events over the course of simply 20 days, a brand new examine has proven.
It’s believed to be the shortest recorded time between two infections because the begin of the pandemic. Because the arrival of the extremely infectious Omicron variant, reinfections have turn into much more outstanding.
The 31-year-old lady from Spain first turned contaminated with Delta in December 2021 – 12 days after she had obtained her Covid booster vaccine.
After testing constructive by means of routine healthcare testing, the ladies went into isolation for 10 days. She didn’t show any signs.
However simply days after returning to work in January, she began to develop a cough and a fever and started feeling usually unwell. She subsequently took a check, which yielded a constructive consequence.
Lab evaluation confirmed that she had initially been contaminated by the Delta variant, adopted by Omicron.
Her case, which is being introduced to the European Congress of Medical Microbiology and Infectious Illnesses in Portugal, is believed to symbolize the shortest recorded time between two separate infections.
Dr Gemma Recio of the Institut Catala de la Salut in Spain, who is among the examine’s authors, mentioned: “This case highlights the potential of the Omicron variant to evade the earlier immunity acquired both from a pure an infection with different variants or from vaccines.
“In different phrases, individuals who have had Covid-19 can’t assume they’re protected towards reinfection, even when they’ve been absolutely vaccinated.
“Nonetheless, each earlier an infection with different variants and vaccination do appear to partially shield towards extreme illness and hospitalisation in these with Omicron.
“This case additionally underscores the necessity to perform genomic surveillance of viruses in infections in those that are absolutely vaccinated, and in reinfections.
“Such monitoring will assist detect variants with the power to partially evade the immune response.”
Reinfections at the moment are taking part in an more and more outstanding position in fuelling the pandemic, information suggests, having turn into much more commonplace.
Within the UK, figures from the Workplace for Nationwide Statistics counsel that the speed of reinfection has elevated fifteenfold because the arrival of Omicron, and that reinfections at the moment account for about 10 per cent of all instances in England, in comparison with simply 1 per cent throughout November 2021.
As much as 6 February 2022, there had been over 14.5 million major infections and round 620,000 reinfections in England – one reinfection for each 24 major infections.
It’s been identified because the starting of the pandemic that reinfections might happen. One of many first reinfections reported was in a 33-year-old man from Hong Kong. His preliminary an infection was identified on 26 March 2020, together with his second an infection, through a genetically distinct virus, identified 142 days later.
Reinfections have turn into extra widespread since then, with scientists attributing this development to waning immunity.
