NEW YORK — Antonio Banderas says he has tested positive for COVID-19 and is celebrating his 60th birthday in quarantine.

The Spanish actor announced his positive test in an Instagram post on Monday. Banderas said he would spend his time in isolation reading, writing and “making plans to begin to give meaning to my 60th year to which I arrive full of enthusiasm.”

“I would like to add that I am relatively well, just a little more tired than usual and hoping to recover as soon as possible following medical instructions that I hope will allow me to overcome the infection that I and so many people in the world are suffering from,” wrote Banderas.

Earlier this year, Banderas was nominated for the Academy Award for best actor for his performance in Pedro Almodóvar’s “Pain & Glory.”
