Measles
Measles is a childhood disease caused by a virus. It used to be widespread, but now it can almost always be prevented with a vaccine. Also known as rubeola, measles spreads quickly and can be very serious or even deadly for small children. Although more kids are getting vaccinated and death rates are decreasing worldwide, measles still kills over 200,000 people each year, primarily children. Due to high vaccination rates, measles hasn’t been widespread in the United States for about 20 years. Most recent measles cases in the U.S. came from outside the country and happened to people who were unvaccinated or didn’t know if they had been vaccinated. Visit our Information on Measles page to learn more.
The Communicable Disease and Community Preparedness (CDCP) branch is responsible for the investigation of communicable diseases and surveillance of reportable diseases.
