Although no ATP of WTA tennis player has tested positive for the virus, it is unknown when order will be restored.
The coronavirus has been particularly harmful in Switzerland — the death toll rose to 43 on Friday and hospitals are reportedly approaching capacity.
Amid the global health crisis, Federer posted a video message to his Instagram on Saturday, begging his followers to stay at home and abide by the recommended social distancing requirements.
"I'm also staying home, and I haven't been shaking anybody's hands for quite some time now," Federer said.
"I wash my hands very frequently as we're supposed to. I believe helping each other is more important now than ever, especially because we want to help the older generation.
"They're the ones at highest risk, and we need to help them by keeping a distance of two metres and not shake hands.
"It's really important to take these rules seriously. Very very seriously.
"Eventually, we could all be in quarantine and not be able to leave the house anymore, so I really hope all of us take it very seriously."
The 20-time Grand Slam singles champion boasts 7.4 million followers on the social media site.
American tennis star Serena Williams also shared a video regarding the coronavirus outbreak, discussing the impact isolation has had on her family.
In a series of Instagram stories where she donned a variety of bizarre tutus, the 23-time Grand Slam champion discussed the anxiety she has experienced since closing herself off from the rest of the world.
"It started out with me feeling like, 'Oh, it can't really affect me.' And then suddenly, Indian Wells was cancelled," Williams said.
"I was like, 'Oh, OK, that's weird, but I have a little time off, and I'm gonna enjoy that time off.' And that one cancellation led to another and led to another and then led to all this anxiety I'm feeling.
"I've been social distancing for actually a really long time, for probably, like, two weeks now. But every little thing makes me really crazy.
"And by anxiety, I mean, like, I'm just on edge any time anyone sneezes around me or coughs I get crazy. And I don't hang out with anyone.
"When I say anyone, I mean my daughter. She coughed, and I got angry. I gave her a side-eye. I gave her that 'angry Serena,' and then I got sad.
"I was like, 'Is she OK? Is there something wrong with my daughter? Like, is there anything I can do?' And I just don't know what to do.
"Instead of being relaxed, I'm really under a ton of stress."
