This variant was first recorded in early 2025 and has now appeared in at least 22 countries around the world . This is a variant of XDV.1, a combination of two strains JN.1 and XDE, identified in 6/8 patients hospitalized at the Hospital for Tropical Diseases in Ho Chi Minh City last week, accounting for 83%.
Currently, WHO has not classified NB.1.8.1 as a cause for concern, but experts say this could be the reason why cases in Ho Chi Minh City are increasing rapidly again.
Week 20 recorded 26 new cases, many times higher than the average at the beginning of the year./.
