Measles Health Advisory 3/14/24

There are currently various Measles outbreaks happening in the United States and internationally, which increases the chance of exposure to Measles at this time. 

What is Measles?

Measles is a highly contagious viral infection that spreads from person-to-person. A person with measles can spread the disease to others even before they have any symptoms. Most people who have not been immunized against measles will get it if they have contact with the virus.

Measles is spread through a cough or sneeze by a person with measles and can still infect others 2 hours after the infected person has left a room. Persons with measles are contagious from 4 days before until 4 days after the rash appears. The incubation period for developing measles is up to 21 days after being exposed to someone else who has the disease. 


Signs of the disease include but are not limited to:

  • High Fever (over 101°F)
  • Cough
  • Runny nose
  • Red watery eyes
  • A rash that starts on the face and spreads to the rest of the body 

If you think that you or someone in your family has measles or has been exposed to measles, contact your doctor's office right away. Let them know you might have measles before you go in, so they can take steps to prevent other patients and staff from being exposed.


The best way to keep from getting and spreading measles is to get the measles immunization. Measles immunization is available at your doctor’s office, local pharmacy or health clinic. The Fresno County Department of Public Health - Immunization Clinic offers no or low-cost immunizations for individuals who are uninsured or underinsured.
