Scientists say the UK's current social distancing measures may need to be in place for quite some time.
Specifically, for as long as it takes to find a coronavirus vaccine.
Two new studies say there's a risk of pushing the rate of transmission too high if social interaction isn't severely limited for the foreseeable future.
The first, from the London School of Hygiene & Tropical Medicine, said social contact would have to be limited to around 5 to 10 people.
