The number of positive coronavirus cases is now up to 53 in Michigan, the state Department of Health and Human Services announced late Sunday night.

It announced 20 additional positive cases on Sunday from the day before. Among the 20 new cases announced Sunday was a male child from Oakland County who had contact with a person with the coronavirus.

The 53 number crept up eight cases from the 45 cases that Gov. Gretchen Whitmer announced just hours earlier on Sunday.

The late-night tally, which appears to include cases that Whitmer announced earlier Sunday, include residents of Washtenaw, Oakland, Macomb, Kent, Wayne, Ottawa and St. Clair counties, according to a state release.

Health officials recommend all Americans take these steps to prevent the spread of COVID-19 and other infectious diseases:

Wash your hands often with soap and water for at least 20 seconds.

If soap and water are not available, use hand sanitizer that contains at least 60% alcohol.

Avoid contact with people who are sick.

Use a tissue or our sleeve to cover your mouth when you cough or sneeze.

Avoid touching your mouth, nose or eyes with unwashed hands.

Clean frequently touched surfaces, such as door knobs, railings, counter tops, remote controls, cabinet handles and light switches.

Practice social distancing, keeping at six feet between yourself and someone who is coughing or sneezing.

If you have COVID-19 symptoms, such as fever, cough or difficulty breathing, contact your health care provider in advance to tell them about your symptoms. Do not go to the doctor's office or hospital without contacting them first.

Seniors and people with underlying health conditions such as lung disease, diabetes, heart disease or a weakened immune system are at highest risk for COVID-19 complications.

If you suspect you may have COVID-19 contact your local health department; find information here.
