While COVID-19, the disease caused by the novel coronavirus SARS-CoV-2, is generally a respiratory infection with coughing and shortness of breath as key features of the illness, some people have reported other symptoms, including loss of smell, heart trouble, and diarrhea.

These less common symptoms, especially cardiac ones, have caused hospitals to adapt their intake protocols to spot possible COVID-19 patients, says Salim Virani, a cardiologist at Baylor College of Medicine. “Almost all hospitals that I’ve talked to, everybody has a protocol whereby they are testing these patients for COVID-19 as well,” Virani says about people who arrive at the emergency department with heart concerns.
