The unnamed 19 year-old was among 367 people to have died in the previous 24 hours, according to figures from NHS England.

Coronavirus poses a relatively low risk to young people overall. Research by Imperial College London found that fewer than 5% of people who caught the illness under the age of 50 needed to be hospitalised in China and Italy, rising to 24% for 70-79 year-olds.
Only 5% of under-40s who were hospital required critical care, compared with 27% of people in their 60s, 43% of people in their 70s, and 71% for those over 80.
