The United States is experiencing a multi-state measles outbreak that started in California last month. Measles is a highly contagious, viral illness. Symptoms generally appear seven to 14 days after a person is infected and begin with fever, cough, runny nose and red, watery eyes. A rash appears within five days after symptoms start. Infection can cause pneumonia, encephalitis and death. Measles is still common in other countries. Infection can be prevented with the MMR vaccine. The Centers for Disease Control says all children should be immunized for measles, as well as adults born after 1957 that do not have evidence of immunity. If you have questions about whether or not you should receive a vaccine, call the Northwest Colorado Visiting Nurse Association. In Craig, call 824-8233. In Steamboat, call 879-1632.
