Measles is a highly-contagious, acute viral illness that is transmitted by contact with an infected person through coughing and sneezing. People who may have been exposed to measles should take precautions and contact their health care provider if they develop any symptoms.

The disease will usually cause rashes that begin as flat red spots. They might appear on the face at the hairline and spread downward to the neck, trunk, arms, legs and feet. Patients are considered to be contagious from four days before until four days after the rash appears.

Symptoms of measles generally include a rash that appears 7-21 days after exposure. Measles
might also begin with a high fever, cough, runny nose and red or watery eyes.

Anyone suspected of having measles should immediately report suspected cases to the local public health agency or to DHSS at 573-751-6113 or 800-392-0272.
