JK Rowling has thanked fans for their messages of support after revealing she’d been experiencing symptoms of coronavirus for the last two weeks.

On Monday, the Harry Potter author tweeted a video to her 14.5 million followers of a doctor at Queens hospital, Romford, demonstrating breathing techniques intended to help those showing symptoms of Covid-19, the disease caused by coronavirus.

Alongside the clip, the 54-year-old revealed that for the last two weeks she’d shown “all symptoms” of coronavirus, and did the exercises in the video on the advice of her husband, who is a doctor.

“I’m fully recovered & technique helped a lot,” she explained.

She also stated that while she had shown symptoms, she had not been tested for coronavirus.

An hour later, she added: “Thank you for your kind and lovely messages! I really am completely recovered and wanted to share a technique that’s recommended by doctors, costs nothing, has no nasty side effects but could help you/your loved ones a lot, as it did me.

“Stay safe, everyone.”

Rowling announced last week that she was launching a new website titled Harry Potter At Home, full of activities for fans of the franchise to get stuck into while on lockdown.

She tweeted at the time: “Parents, teachers and carers working to keep children amused and interested while we’re on lockdown might need a bit of magic, so I’m delighted to launch HarryPotterAtHome.com”

A synopsis on the website explains: “Welcome to the Harry Potter At Home hub where you’ll find all the latest magical treats to keep you occupied – including special contributions from Bloomsbury and Scholastic, nifty magical craft videos (teach your friends how to draw a Niffler!), fun articles, quizzes, puzzles and plenty more for first-time readers, as well as those already familiar with the wizarding world.

“We’re casting a Banishing Charm on boredom!”
