Another death due to COVID-19 was reported in Clark County on Friday, bringing the toll thus far to six.

Also, another 28 tests returned positive for the communicable disease. Since the first local case was confirmed on March 7, a total of 76 people have been positively diagnosed with the novel coronavirus. On Wednesday, the number of positive diagnoses was 20.

Another 653 tests have returned negative for the virus, which shares symptoms with other common illnesses such as flu.

Clark County Health Officer Dr. Alan Melnick said Thursday that the number of confirmed cases is on the rise for two reasons. First, more tests are available for people who show symptoms of the virus, and the results of previously administered tests are being received. And second, it is likely that more disease transmission is occurring.

Public health officials are warning people to stay home this weekend, except for essential trips to buy food or medicine. People should avoid getting together with friends or congregating in outdoor locations.
