And a Danish preprint study found last month it is possible to have had Omicron's original strain, BA.1, and then get the sub-variant, BA.2.

Danish scientists confirmed Tuesday that the BA.2 subvariant can reinfect people who previously had its omicron predecessor, BA.1, though the risk of catching the virus again appears low. This is a change to the previous methodology from the UK Health Security Agency (UKHSA), by which people who tested positive for Covid-19 were counted only once in case numbers published on the daily dashboard, when they first tested positive.

The return to the new normalmaskless workspaces and airplanes, for examplemay increase the probability of reinfections from different variants.
