Jared Leto has only just learned about the severity of the COVID-19 outbreak across the world after emerging from 12 days in the desert.
The Suicide Squad star said he'd been "totally isolated" during a meditation retreat, and on reintegrating to society found the world "very different" than when he left it.
"Wow. Twelve days ago I began a silent meditation in the desert. We were totally isolated. No phone, no communication etc. We had no idea what was happening outside the facility," Leto wrote on Twitter.
"Walked out yesterday into a very different world. One that's been changed forever. Mind blowing - to say the least. I'm getting messages from friends and family all around the globe and catching up on what’s going on."
Leto told his 4.4 million followers he hoped they were all okay, and urged everyone to "stay inside and stay safe".
"Sending positive energy to all."
Meanwhile, other Hollywood heavyweights including Tom Hanks and Idris Elba have revealed they tested positive for coronavirus. Hanks and his wife Rita Wilson were recently released from hospital and are continuing their recovery in self-isolation, while Elba says he didn't have any symptoms.
