Peterborough Public Health is reporting the first locally acquired case of measles in the region in more than 10 years.
The case involves a fully vaccinated adult, which qualifies as a “breakthrough case.” While uncommon, PPH says breakthrough infections can occur, though they typically result in milder symptoms than infections in unvaccinated individuals.
The source of exposure has not been identified. Investigations are underway to determine where the individual may have contracted the virus and to identify others who may have been exposed.
Measles outbreaks have been reported in several regions across Ontario in recent months, including in neighbouring health units. This marks the first confirmed case in the Peterborough area during that time.
PPH has released a list of known public exposure sites and times associated with the case:

If you believe you have been exposed at any of the dates and locations above:
1. Check your vaccination record. Confirm that household members have received two (2) doses of the measles vaccination (MMR or MMRV). If you have 2 doses of measles vaccine, you are not considered susceptible.
2. If you do not have two doses or are unsure, notify Peterborough Public Health. Please call 705-743-1000.
3. Consider vulnerability and need for post-exposure care. If you were exposed AND are immunocompromised, unvaccinated, or pregnant, contact PPH at 705-743-1000 to assess eligibility and need for post-exposure care.
4. Monitor for symptoms. Stay home if you develop any symptoms. Contact PPH (705-743-1000) and notify them that you may have measles. Always phone any clinic, emergency department, or health care setting before attending if you have been exposed or are experiencing symptoms.
PPH is continuing to monitor the situation and will provide updates, as necessary. Learn more about measles and vaccination, including a video from Dr Thomas Piggott, at www.peterboroughpublichealth.ca/measles.
