A new app launched by scientists in the battle against coronavirus suggests 1.9 million people in the UK are infected.
Experts from Kings College London made the Coronavirus Symptom Tracker, which predicts nearly 2 million people aged between 20 and 69 are infected, alongside Guy’s and St Thomas’ NHS Trust.
It comes as the UK’s cases jumped to 38,168 and deaths rose to 3,605.
Contributors can track their daily health on the app, which is also being used by health professionals across the country, with early user data showing nearly two million have symptomatic Covid-19.
Researchers also found it shows wide disparities in the location of hotspots, which include cities such as London, Birmingham, Manchester, Liverpool, Glasgow and Belfast.
South Wales is also flagged by the data as badly affected, following a shortage in hospital beds.
