Measles Update

As of February 28, 2019, 206 cases of measles have been reported to CDC from 11 states. There currently are NO cases of measles in Montana. Most cases in 2019 are part of a large outbreak in Clark County, Washington. Given the proximity of this outbreak to Montana, we may have travelers to and from the area, which could increase the risk of exposure to Montana residents.

Measles is an extremely contagious virus that can be dangerous, especially for young children. The measles virus can survive in a room for up to two hours after an infected person leaves the space. If exposed to the virus, anyone who is not immune is likely to get measles.

Public health authorities are recommending a proactive approach to prepare for the possible introduction of measles into our state. One important activity includes reviewing the immunization status of your family.

People are considered immune to measles if any of the following are true:

1. You are a pre-school age child with one measles vaccine (MMR – measles, mumps, rubella) 2. You are a school-age child (K-12) who has had two measles vaccines (MMR - measles,mumps, rubella). 3. You were born before 1957, or have received at least one-dose of measles vaccine. 4. You have had measles disease (diagnosed by a health care provider and confirmed with a lab test). 5. You have had a blood test that shows you are immune to measles.

The good news is that the vast majority of local residents are protected by vaccination or natural immunity. The measles vaccine was licensed in 1964 and a second dose was recommended in 1989. A side note, the vaccine was developed by Maurice Hilleman who grew up in Miles City.

If you’re not protected against measles and think you might have been exposed to someone with measles: Stay home. DO NOT go straight to the doctor. Instead, call ahead to inform a healthcare professional of your possible exposure so you can get instructions about how to avoid exposing others.

Remember: vaccination is the best way to prevent measles. Anyone who has received two doses of a measles-containing vaccine is highly unlikely to get measles.

If you have questions on your immunization status, contact your local public health department. Up to date information on measles activity can be found at the DPHHS website. Visit www. dphhs. mt.gov and select the measles banner to access our updates.
