All four patients are adult males in Kent County, DPH said.

DPH officials are working on contact tracing to identify and notify anyone who might have been exposed to the virus.

Why you should care:

Measles is a highly-contagious virus that can cause a high fever, cough or rash, and in some cases can lead to pneumonia, swelling of the brain and even death, according to the CDC. People who are unvaccinated, pregnant or too young for vaccination are at the highest risk.

What to do if you're exposed

What you can do:

Measles symptoms include high fever, cough, runny nose, red, watery eyes and a rash. 

DPH officials recommended anyone showing symptoms should contact their doctor. If you're unvaccinated, experts recommend getting the MMR vaccine, which DPH says is 97% effective at preventing measles after two doses.
