Amid the return of summer travel, two variants are causing spikes in COVID-19 cases.
BA.5, which accounts for 65% of cases, and BA.4, which is 16% of cases, are omicron's smarter cousins. The two subvariants are evading antibodies and even vaccine protections, as they are believed to be the most contagious versions of the virus yet.
Since the subvariants derived from the original omicron variant, symptoms fall under the same umbrella. However, symptoms still vary depending on vaccination status, age, prior infection, medication and other factors, said Kohli.
Data collected from the Zoe app in the UK show most symptoms mimic the common cold, with sore throats and runny noses. Kohli said a significant change in symptoms for the subvariants are heightened amounts of sneezing, something not seen in earlier forms of the COVID-19 omicron variant.
