The emergence of two new variants of Covid-19 is a stark reminder that we're not out of the woods yet when it comes to the deadly virus. The Omicron variant continues to mutate and, as a result, two new variants have been discovered.
In his latest YouTube video, Professor Tim Spector, of the ZOE Covid Study app, gave the latest update on the two new variants, dubbed BA.4 and BA.5 according to The Express.
Professor Spector has also revealed the two symptoms we need to take "very seriously". "We are keeping an eye on this because South Africa - where Omicron was first picked up - is seeing BA.4 and BA.5 increasing quite fast". Meanwhile, he said loss of smell and tinnitus - also known as ear ringing - are symptoms to take "really seriously", although the former was more associated with previous strains.
