Eighty percent of patients with coronary heart disease have mild, common cold-like symptoms. According to the US Centers for Disease Control and Prevention (CDC), 25 percent of patients have no symptoms at all. Such patients are recovering after being infected unknowingly. However, they are playing a role in spreading the infection. The number of children and teenagers in this group is more. A portion of the patients are again pre-symptomatic. I mean, their symptoms are a little late. But before that they started spreading the virus. So even if you don't have a fever or cough, you or everyone around you is safe and tax-free. In this case, the CDC's advice is to stay at home as long as the lockdown is on, adhere to social distance, wear a mask.
