Dr Rosena Allin-Khan warned the number of coronavirus cases in London is growing quickly, as she admitted patients in their thirties are now being affected and left fighting for their lives. The Labour MP said the UK is heading for a disaster after serving a weekend shift at St. George’s Hospital in Tooting, south London. Speaking to the BBC, Dr Allin-Khan said: “There is a very real sense that the number of cases is growing and now growing very, very quickly.

“Some of the most startling news seems to be that some of the sickest patients that we have had in this department recently have been young.

“We have patients who are in their 30s and early 40s who were previously fit and well who are now in intensive care and fighting for their lives.

“This is a virus which is very, very difficult to predict.”

Dr Allin-Khan said patients with other health conditions had to be moved to children’s wards to make space for COVID-19 and predicted doctors will soon have to make the heartbreaking decision of who does and does not get the last ventilator.
