Over 66 percent of Omicron cases are reinfections: study

More than two-thirds of cases of the Omicron variant of COVID-19 are among people who have been re-infected with the virus, a new study said Wednesday.

Imperial College London researchers reported that about 3,582 people – or about 66% of study participants – who tested positive in January had already been infected with the virus, CNBC reported.

A further 7.5% of infected participants said they thought they had the virus before, but did not confirm it with a test.

The study looked at more than 100,000 PCR tests collected across the UK between 5 January and 20 January.

The study’s authors said in a paper released on Wednesday that the Omicron variant has hit England at “unprecedented levels” and has almost replaced Delta as the country’s most prominent variant, CNBC reported.

The investigation comes as officials announced that wearing masks will no longer be mandatory and the public will no longer be advised to work from home from Thursday in England.

Health authorities said last month that about half of Omicron cases in the UK were among those fully vaccinated.

Nearly 85% of the country’s eligible population is fully vaccinated, and 64% have received a booster shot, CNBC reported.

In December, UK health authorities also estimated that the risk of re-infection with the Omicron variant was about 5.4 times greater than with Delta.

Omicron is a mutated version of COVID-19 that has been identified in over 170 countries, CNBC reported. World Health Organization officials reported Monday that since the variant was identified nine weeks ago, more than 80 million virus cases have been reported to the agency.

Britain reported 94,326 new COVID-19 cases on Tuesday, CNBC reported. The number of infections peaked at the end of December, when 246,415 positive tests were recorded in one day.
