People who had Covid-19 and are later reinfected with the omicron variant may experience fewer symptoms than they did during their initial bout with the virus.
In May 2022, a preprint indicated Omicron subvariants BA.4 and BA.5 could cause a large share of COVID-19 reinfections, beyond the increase of reinfections caused by the Omicron lineage, even for people who were infected by Omicron BA.1 due to increases in immune evasion, especially for the unvaccinated. However, the observed escape of BA.4 and ...

After nearly two months of lab studies and real-world observations, experts have a much clearer picture of what Omicron is — and isn’t — capable of.
A news article on Nature reports there are signals that Omicron does not multiply readily in lung tissue. The latest results could mean that "the virus establishes a very local infection in the upper airways and has less chance to go and wreak havoc in the lungs", which might make it easier "to hitch a ride on material expelled from the nose ...
