WHO: those who had COVID-19 may be reinfected more easily with Omicron

WHO’s Technical Advisory Group on Virus Evolution reaffirmed that preliminary evidence indicates that people who have previously had COVID-19 could become reinfected more easily with Omicron when compared to other variants of concern.

So far, the initially reported infections have been among younger individuals who tend to have more mild disease, “but understanding the level of severity of the Omicron variant will take days to several weeks”, the experts said.  

The group emphasised that is working with partners to understand the potential impact of this variant on vaccines, the effectiveness of current PCR tests, and existing treatments, but more information is still needed.
