It only took a few days for the Wisconsin patient to get over the fever and a cough — and feel well enough to get out of bed and back to normal life: shop for groceries, hang out in a coffee shop, maybe see a new movie.

But that wasn’t an option, because the patient wasn’t getting over the common cold or even the flu. Instead, the individual had the new coronavirus, meaning it would be several weeks before the person — who remains unidentified for privacy — could leave the house or invite friends and family to visit.

“For most people, this will be the course. It will be like a cold,” Dr. Nasia Safdar, the patient’s physician, told NBC News.

So far, at least 15 people with confirmed coronavirus infections in the United States are said to have made full recoveries. In addition to the Wisconsin patient, six people in California, four people in Nebraska, two people in Illinois, one in Arizona and one in Washington are better.
