"Harry Potter" author J.K. Rowling said on Monday she had recovered from a suspected case of COVID-19 after two weeks of illness.

"For last 2 weeks I've had all symptoms of C19 (tho haven't been tested)," Rowling said on her Twitter account. She also shared a video of a breathing technique that she said had helped her manage her worst symptoms and had been recommended by her husband, who is a doctor in the U.K.
