Currently, the risk to the general public for COVID-19 to cause severe illness is low. At this time, there are a small number of individual cases in the U.S. Older adults and those with serious conditions such as heart disease, diabetes, lung disease and any condition that affects the immune system could be at higher risk. Additionally, travelers to and from certain areas of the world may be at increased risk. See wwwnc.cdc.gov/travel for the latest travel guidance from the CDC.
