At this time, LPH is working to identify known contacts who may have been exposed. This exposure is not connected to either of the previously announced laboratory confirmed cases.

Anyone who may have been exposed at the above location should contact LPH at 519-383-8331 if you fall into one of the following categories:

LPH will help determine your eligibility for post-exposure measures.

All exposed contacts should monitor for symptoms of measles which can appear up to 21 days after exposure but usually occur within 7-12 days. If you develop symptoms of measles (e.g., fever, rash, red eyes) self-isolate at home immediately and do not attend public places (such as work, school, childcare, or shopping centres) or use public transport. If symptomatic, it is important to call your health care provider or any health care setting you might need to attend ahead of time, to alert them of your symptoms and exposure to measles so appropriate precautions can be taken.

Measles is a highly contagious virus that is spread through the air when someone with measles breathes, coughs, or sneezes. The measles virus can live for up to two hours in the air. LPH is reminding the community to be aware of the signs and symptoms of measles, which include fever, a red blotchy rash, red watery eyes, and Koplik (white) spots in the mouth.

If you think that you or a family member has symptoms of measles, self-isolate at home, and call your health care provider immediately. If you need to visit a health care provider or any health care setting, please call first and inform them that you have measles symptoms so appropriate precautions can be taken.
