A new sub strain of the Omicron Covid variant has a higher growth rate and could be more transmissible, the UK Health Security Agency (UKHSA) has said.
Known as the BA.2 Covid strain, the variant is said to spread faster than the original and is thought to have been identified more than 420 times in the UK since November, with cases multiplying in some parts of Europe and India.
Also known as the 'Stealth Variant', it is now known to be circulating in more than half of all USA states, the Centers for Disease Control and Protection (CDC) announced yesterday.
