Nearly 7 months after the WHO withdrew the public health emergency notification for Covid-19, the virus refuses to go away. The Omicron variant has mutated into several new subvariants, with the latest, JN.1, causing a surge in Covid cases. While experts said they will wait for a few more days before calling it a new wave and there’s no need to panic, they warn that the WHO-declared “variant of interest” may not be the last on the list. Vulnerables advised to take vaccine.
