Hello, everyone.
On Monday, Japan announced the discovery of the first case of the XE variant of the Omicron strain of coronavirus at a routine check-in an airport.
The strain was detected at Narita airport in a woman in her 30s who had arrived on a flight from the US on March 26. The variant is a combination of the Omicron BA.1 and BA.2 subvariants which, as the World Health Organization estimates, makes its transmissibility 1.1x higher.
As individuals experience an increase in international mobility, there is a concern that this variant will replace the current Omicron variants. Kyoto University’s mathematical modeling expert Hiroshi Nishiura says that more information is needed to understand the full epidemiological impacts on the body.
