Most people in Virginia have immunity to measles through vaccination, so the risk to the general public is low. See the VDH Measles in Virginia webpage for updated exposures information for all of Virginia.

If you were at any of the potential exposure sites at the dates and times listed, complete this short VDH survey to report your exposure to VDH.
Public health officials will follow up with you if additional actions are needed.

Any additional exposure locations identified outside Virginia are reported by the affected states.

If you are notified that you may have been exposed to measles, you should monitor for signs/symptoms of measles for 21 days (3 weeks) after the last exposure, especially if you:

are not fully vaccinated or otherwise immune to measles -OR-
have an unknown measles vaccine history -OR-
only received a single measles vaccine in the 1960's without documentation of receiving a LIVE measles vaccine

People are generally considered immune to measles if they are up to date on measles vaccination, have had a laboratory confirm they either had measles during their lifetime or are immune to measles, or were born before 1957.
