  • Call your physician office
  • If after trying all of the above you cannot find documentation, call your physician office and discuss having a titer drawn
What if I am not immune and either cannot receive or choose not to receive the vaccine?

In the event you would be exposed to a measles case and you could not provide documentation of immunity, you or your child would be quarantined for up to 2 weeks. This means that you would be required to remain at home to reduce the chances of spreading the virus. People infected with measles can spread the virus for 4 days before the rash starts through 4 days after the rash so a person may not even realize they are infectious.

If you have any questions, please do not hesitate to give a nurse form the Communicable disease Division a call at 920-232-3000.
