Measles is a highly contagious viral illness that spreads through the air when an infected person coughs or sneezes. The virus can remain in the air for up to two hours after an infected person leaves an area. Symptoms typically develop seven to 21 days after exposure and may include fever, cough, runny nose, red eyes and a rash.
“Symptoms of measles include fever, cough, runny nose, red or watery eyes, and a rash that starts on the face and spreads down the body. People who get sick with these symptoms should call their healthcare provider for guidance. Calling ahead in non-emergency situations helps prevent additional exposures. If you have symptoms of measles, stay home and avoid contact with others unless you are getting healthcare.” –Wyoming Department of Health
Individuals who were at the listed locations during the identified time windows should monitor themselves for symptoms for 21 days following their potential exposure. Anyone who develops symptoms should call their health care provider before seeking medical care so appropriate precautions can be taken to prevent exposing others.
