Doctors are urging people to get tested for COVID-19 even if they think that they might just have a cold.

Keith Seigerman, of Southampton, says he had coughing and sneezing after getting back from a trip to Aspen, Colorado. His partner and sister also got a similar head cold. All three have been fully vaccinated since March.

Seigerman says they decided to get tested despite a walk-in clinic saying it was just a summer cold. All three of them ended up testing positive for COVID-19 and hae been in quarantine ever since.

"The thing is we let our guard down when we were in Aspen," says Seigerman. "We stopped wearing masks and we shouldn't have. I was told that I could have a normal experience. I was told that I could go to concerts and do these things."

Doctors say fully vaccinated or not you can still spread the virus.

Chief Medical Officer Dr. Marc Adler, of NYU Langone Hospital Long Island, says even if you're showing the mildest of symptoms you should get a COVID-19 test.

"Sniffles sore throat upset stomach mild cough - they can mimmick COVID as well as other viruses we typically see this time of year," says Adler. "It’s more important now more than ever to be tested so we know how to protect ourselves and the rest of the community."

Seigerman says he agrees and it's better to be safe than sorry.
