The number of confirmed cases in the U.S. is rising as testing improves and as more people contract the disease. This graphic shows how many new cases have been confirmed across the country on a day-by-day basis.

What are the symptoms?

The novel coronavirus that causes the disease COVID-19 has spread from the site of the original outbreak in China to affect 75 countries around the world. If effective controls aren’t put into place, COIVID-19 could ultimately infect between 40% and 70% of the population worldwide in the coming year, according to Harvard T.H. Chan School of Public Health epidemiologist Marc Lipsitch

Most of those cases would be mild, and some people might show no symptoms at all. But the prospect of being infected with a new virus can be frightening. The symptoms to look out for, according to the Centers for Disease Control and Prevention (CDC), are fever, coughing and shortness of breath. These symptoms usually appear between two days and two weeks of exposure to the virus. 

According to a report in the Journal of the American Medical Association, as many as 98% of COVID-19 patients have a fever, between 76% and 82% have a dry cough, and 11% to 44% report exhaustion and fatigue.
