A 21-year-old woman in the UK, who had no underlying health complications, has died after contracting the coronavirus.

Chloe Middleton died on Saturday, according to Sky News. She is believed to be the UK’s youngest victim with no underlying health issues.

Diane Middleton, who identified herself as Chloe Middleton’s mother, posted a warning on Facebook on Tuesday.

“To all the people out there that thinks it’s just a virus please think again,” she wrote, “speaking from a personal experience this so called virus has taken the life of my 21 year old daughter.”

The majority of the victims of the coronavirus have been the elderly and those with preexisting health conditions.

However, medical experts have been urging young people to take the threat of the virus seriously, not least because if they contract it they may pass it on to someone vulnerable.
