American singer-songwriter Christopher Cross shared on his Facebook page that he has tested positive for coronavirus.

"Although I am fortunate enough to be cared for at home, this is possibly the worst illness I've ever had," the five-time Grammy winner said.

The 68-year-old said in his post, "Dear Friends, I’m sorry to report that I am among the growing number of Americans who tested positive for the COVID-19 virus. I’m not in the habit of discussing medical issues on social media, but I do so in hope this will help other people to understand how serious and how contagious this illness is."

"For those of you who still do not believe the COVID-19 virus is real, or think it is a 'hoax' or part of some conspiracy, my advice to you is to understand right now that this is a deadly illness spreading like wildfire throughout the world," he said. 

"PLEASE make every attempt to stall the spread of this virus by: 1) staying home - the only way we can stop the spread right now is by self-quarantine 2) washing your hands as many times a day as you can and don’t touch your face and 3) follow the SCIENCE," he said. 

"Importantly, please read the guidelines posted at the Centers for Disease Control and Prevention to educate yourself on the facts and protect your loved ones," added the musician. 

Cross signed off his message by saying, "Last but never least: wherever you are in the world, let’s all be kind to one another. Only if we work together can we defeat COVID-19."
