LITTLE ROCK, Ark. (AP) — Arkansas health officials reported another 488 cases of COVID-19 Sunday while the number of deaths due to the illness caused by the coronavirus rose by 18.

There are now 1,425 reported deaths, 1,278 confirmed and 147 probable, due to COVID-19, according to the Arkansas Department of Health. That’s up from 1,407 Saturday.

The department reported 83,306 confirmed cases of the virus and another 3,707 probable cases Sunday, compared to 82,851 confirmed and 3,674 probable cases a day earlier. There are 1,424 active cases, according to health officials.

The actual number of cases in Arkansas is likely higher because many people have not been tested, and studies suggest people can be infected and not feel sick.

For most people, the new coronavirus causes mild or moderate symptoms that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia, and death.
