A doctor from Portland has proved himself the right medicine as he bring smiles on thousands of faces through his dance moves during this time of disaster.

Dr. Jason Campbell has made waves online after his “corona foot shake,” “the cha-cha slide” and other dance moves along with his colleagues went viral.

The 31-year-old doctor told that he feels so much honoured by the positive response including from health care workers in New York.

“When you’re in medicine, you see a lot of serious, sad things all the time,” Campbell said.

“And so we too need a way to remain human, stay sane and a chance to just smile or laugh, even if it’s just five minutes out of a 12-hour day.”

Campbell said he initially began posting the videos to encourage teens, especially African-American youths, to pursue their dreams and know that they too could become physicians.

However, the TikTok clips cheered up a wider audience during these difficult times.

Campbell’s “corona foot shake” video alone has been watched four million times.

“I got a message today (Friday) from someone who said his wife was a cardiologist working with COVID-19 response teams and found the videos so refreshing,” Campbell said.

“The overwhelming response has been, ‘Hey, I work in New York City and I love seeing your video after my long day,” Jason Campbell said.

“Others say, ‘Hey, my family member has the virus and we watch these videos together while they recover.'”

Hospital officials have also applauded the initiative.

The videos have been hailed by the state’s governor and even caught the attention of popular recording artist Janet Jackson, who retweeted one of the doctor’s TikToks.

Campbell said his next dance routine was in response to a special request from his co-workers’ kids.

“It’s going to be a slow-motion challenge with one of my colleague’s daughter,” he said.

“It’s multiple moves where you go slow at first then speed it up back to real time.”
