A man in his 70s has become Clark County’s first confirmed COVID-19 patient.

Clark County Public Health released the confirmation Friday night.

The patient had been receiving treatment in isolation at PeaceHealth Southwest Medical Center, pending test results, and remains in isolation at the hospital, according to PeaceHealth.

Public Health identified “a small number” of people who had close contact with the man, according to a press release issued Saturday morning. Those individuals are instructed to stay home for 14 days since their last contact with him. The man did not recently travel to a country where COVID-19 is spreading, suggesting the virus is circulating in Clark County, according to Public Health.

The department had been awaiting results on nine tests referred to a laboratory for testing. Five results are still pending. Three tests were negative for coronavirus. Five other people, all recent travelers to areas with outbreaks, are under public health supervision.

Public Health is not announcing public locations the man visited, unlike during last year’s measles outbreak. COVID-19 is spread through close contact, within 6 feet, and via respiratory droplets when someone coughs or sneezes. Unlike with measles, which is airborne and can linger for several hours, listing places where someone with COVID-19 has visited is not effective.

“Without close contact with an infected person, you are at extremely low risk of contracting COVID-19,”said Dr. Alan Melnick, Clark County health officer and public health director.
