COPENHAGEN: According to a new study released by Denmark's Statens Serum Institut, reinfection with distinct subtypes of the Omicron form of Covid-19 is feasible (SSI).

"This appears to occur rather seldom in Denmark, and reinfections have mostly afflicted younger unvaccinated individuals," the SSI, Denmark's public health and research institution, said in a paper released on Tuesday.

"None of the affected people were very ill, and none of them required hospitalisation." According to the study, PCR tests on almost two million Danes infected with Omicron sub-types BA.1 and BA.2 indicated "67 examples of the same subject becoming infected twice during a 20-60-day interval where both infections were due to Omicron sub-types."

According to the study, the majority of persons infected with Omicron in Denmark were infected with BA.1, which was also the most common sub-type worldwide until December 2021.

PCR studies found that BA.2 was progressively rising in prevalence in January 2022, to the point that "this variation today accounts for the majority of coronavirus infections in Denmark, whereas BA.1 is now observed considerably more seldom."
