Billie Eilish posted a five-minute Instagram story on Monday, urging young fans to take the coronavirus outbreak seriously.

"I know because a lot of us havent seen it with our eyes, what it's been doing and who it's been affecting, it's hard to understand that it's real," she said. "I've seen a lot of young people out in the world, all over the place, going to the club or going to the beach or just going out and hanging out, and it's really irresponsible."

The 18-year-old said she originally didn't perceive it as a threat, largely because of her age, but came to realize she "can transfer that to someone who's much weaker."

"Please take responsibility for your endurance of this," Eilish told fans. "Because yeah, you could get it and you could be fine, but you could give it to your parents. You could give it to your grandparents, or your aunts, or your uncles, or your friend's mom. It's not about you."

Billie Eilish shared an earnest five-minute video on Monday, urging young fans to take the coronavirus outbreak seriously.

"I wanted to make a video talking about this coronavirus because this s--- is f---ing crazy, and I know a lot of people don't know what the f--- is going on. I don't know what the f--- is going on, I don't think anyone really does. But I know we're all scared and worried," she said in the video, which was posted on her Instagram story.

"It is a really, really big deal right now, and it's not a joke. I know because a lot of us havent seen it with our eyes, what it's been doing and who it's been affecting, it's hard to understand that it's real. But it really is real," she continued. "I've seen a lot of young people out in the world, all over the place, going to the club or going to the beach or just going out and hanging out, and it's really irresponsible. And I'm gonna explain why."

The 18-year-old admitted that, at first, she didn't perceive the virus as a threat; COVID-19, the illness caused by the novel coronavirus, disproportionately kills elderly and immunocompromised people.

"You know, it was like that stupid state of mind, where I'm like, 'I don't give a f--- if I get it.' Or, 'I'm not gonna get it, I'm immune,'" she explained. "And I did not realize that it's not about me. So everybody that's thinking, 'I don't care if I get it,' it's not about you."

Eilish said she came to realize that asymptomatic young people can still carry the virus and "transfer that to someone who's much weaker."

"I wanted to talk about it because I know half the world is freaking out and half the world doesn't give a f---. So I wanted to, just real quick, say: Don't panic, but don't be an idiot," she said. "Please take responsibility for your endurance of this. Because yeah, you could get it and you could be fine, but you could give it to your parents. You could give it to your grandparents, or your aunts, or your uncles, or your friend's mom. It's not about you."

The "Bad Guy" singer also implored her fans to "stop hoarding things" and stocking up on supplies that other people might need more immediately.

"It's not the apocalypse, you guys," she said. "I understand the panic, I'm just trying to say: Relax, but take it seriously. It's a really, really big deal and people are losing their lives. And you gotta take care of yourself and take care of your family and the people that surround you."

"Don't go out. It's OK. It's f---ing easy as f--- to not go out. Like, bro. Stay inside, it's so easy."

Eilish concluded by passing along a piece of advice that helped her grasp the situation at hand.

"I saw something that I thought was a good way of putting it: Live your life right now like you have [COVID-19]. So take care of you and the people around you as if you had it yourself. Don't touch people, don't high-five, handshake, hug — I know it's hard, I'm a really physical person, I understand it's hard. But we gotta take precautions up in here."

Like many artists, Eilish was recently forced to postpone 11 dates on her "Where Do We Go?" tour in response to the pandemic.

Although the teenager said she was "so sad" to reschedule the sold-out concerts, she's now enjoying spending time at home in Los Angeles, where she's fostering puppies to pass the time.

Eilish's advice is in line with recommendations from the US Centers for Disease Control and Prevention, which recently recommended that all gatherings and events of 50 people and more be postponed until May.

As of Sunday evening, the US had confirmed more than 3,660 COVID-19 cases, including at least 68 deaths. Americans have been urged to practice social distancing, regardless of whether they show symptoms or feel threatened by the virus.
