Former "The Bachelor" star Colton Underwood, 28, announced in an Instagram video on Friday that he has tested positive for coronavirus.

"I have been following all of the social distancing rules since last week. My symptoms started a few days ago, I was tested and just received my results today," Underwood wrote on Instagram . "Please do yourself and your loved ones a favor and stay home. We will all beat this and come out stronger on the other side."

Underwood, who had the titular role in the 23rd season of "The Bachelor," said he got tested after he became symptomatic earlier in the week and had been quarantining while he awaited test results.

In the video he posted, he said he was exhausted and was revealing his diagnosis to remind young, healthy people they are also at risk of contracting the virus.

Initial reports from world health officials noted that the novel coronavirus has been most deadly for those over 65 or with underlying health conditions, but scientists have recently issued more stark warnings to millennials and younger people that the disease can also cause them serious harm.

Young people are also encouraged to social isolate as the illness can be spread among those who are asymptomatic.
