COVID cases are in rapid decline in the UK. In this week's video, Tim shares a quick update about the Study, which is now known as the ZOE Health Study! He then focuses on COVID variants, with a first look at the difference between BA.1 and BA symptoms, an update on BA.4 and BA.5 and looks at what's happening in South Africa. This week our amazing ZOE Health Study video team are on a break so there are no graphs in this week's video. We are really sorry for any inconvenience, we will be back to normal videos next week.
