"After a seven-month gap, cases are rising in India. In Kerala, there are reports of people getting Covid, but the severity so far appears to be the same as before," said Rajeev Jayadev, National Indian Medical Association Covid Task Force's co-chairman.

According to news agency ANI, Rajeev Jayadevan has informed that JN.1 variant is capable of spreading faster and evading immunity.

"JN.1 is a severely immune-evasive and fast-spreading variant, markedly different from XBB and all other prior versions of this virus. This enables it to infect people who had previous Covid infections and also people who were vaccinated," he added.
