New COVID-19 sub-variant XEC detected in New Zealand

A new COVID-19 sub-variant, XEC, has been detected in New Zealand. The strain is a mix of two previous Omicron variants and has been found in clinical samples. It is reported to be more transmissible than other sub-variants. Epidemiologists express concern about the potential impact of XEC, which has also been reported in around 30 other countries, including Australia. Experts emphasize the need for a clear strategy to manage its spread. Current vaccines are expected to still provide protection against XEC, although their effectiveness may be somewhat reduced. Experts recommend maintaining vaccination and other preventive measures to combat the new strain.
