In the UK, two-thirds of those infected with the Omicron mutation are COVID-19 ‘reinfected’ cases, a study has found.
On the 26th local time, Imperial College London announced that “65% of the study participants who tested positive for COVID-19 had previously tested positive for COVID-19” in ‘React-1’, a study on the spread of COVID-19 in England.
This study was conducted by distributing about 100,000 PCR test kits to randomly selected participants from January 5 to 20, collecting and analyzing them.
As a result of the study, 99% of COVID-19 infections were micron mutations, and 65% had previously tested positive for COVID-19.
However, there is a possibility that remnants of past virus infection were detected by PCR (gene amplification) test, not reinfection.
The infection rate during this period was 4.41%, more than three times that of a month ago (1.40%). This is the highest number since the study began in May 2020.
By age, students aged 5-11 had the highest infection rate at 7.81%, and those aged 75 and over had the lowest rate at 2.43%. The elderly infection rate is about 12 times higher than it was a month ago.
Professor Paul Elliott, Imperial College Professor Paul Elliott said, “The number of infections decreased rapidly in January, but it is still very high and seems to have stagnated at a high level recently. will,” he said.
