COUGH

Coughing is another key symptom, but it's not just any cough, said Schaffner. It should be a dry cough that you feel in your chest.

FEVER

Fever is a key symptom, experts say. Don't fixate on a number, but know it's really not a fever until your temperature reaches at least 100 degrees.

TIREDNESS

But the pristine forest and surrounding view was more than worth the tiredness that crept into the arms and legs.

Breathing

Shortness of breath can be a third and very serious manifestation of Covid-19, and it can occur on its own, without a cough.

How COVID-19 Spreads

Person-to-person spread

The virus is thought to spread mainly from person-to-person. Between people who are in close contact with one another (within about 6 feet). Through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
