Michigan Governor Gretchen Whitmer spoke at a press conference on Sunday, during which the state of Michigan announced 12 additional presumptive, positive cases of coronavirus/COVID-19.

The new cases bring the state’s total number of positive cases to 45.

Specimens will be sent to the Centers for Disease Control and Prevention for confirmation testing, according to Fox 2 News.

The case locations that have been identifiedf include 9 in Oakland County, 8 in Wayne County, 4 in Washtenaw County, 2 in Macomb County, 2 in Kent County, 1 in Monroe County, 1 in St. Clair County, 1 in Ingham County, 1 in Montcalm County, 1 in Bay County, 1 in Charlevoix County and 2 that are of unknown origin.

Symptoms of COVID-19 may appear more slowly, and usually include fever, a dry cough and noticeable shortness of breath, according to the World Health Organization. A minority of cases develop pneumonia, and the disease is especially worrisome for elderly and those with medical problems such as high blood pressure, obesity, diabetes or heart conditions.

Officials are urging people to wash their hands well and often, keep them away from your face, and to avoid crowds and standing close to people.

Those who do have symptoms are urged to no to go straight to the doctor’s office. Doing so makes is making others sick, officials have said.

It’s important to call ahead and ask if you need to be seen and where.
