Measles can cause serious health complications, including hospitalization, pneumonia, inflammation of the brain, and, rarely, death. It is usually more severe in infants and adults than in children.

What should I do if I develop symptoms of measles or if I was exposed to someone with measles?
If you develop symptoms of measles:
You should be assessed by a physician, and notify the health care facility that you plan to visit so that they are aware of your symptoms prior to your arrival. You should also wear a medical grade mask to the appointment. In the meantime, stay at home to avoid potentially exposing other people.
Measles is diagnosed by a blood test, a urine sample, a nasopharyngeal swab, and a throat swab.
If you are having a medical emergency, call 911 or visit the nearest emergency department. Advise them of your symptoms and if you were exposed to measles. If possible, wear a medical grade mask.
If you were exposed to someone with measles:
Residents of Renfrew County and District should call RCDHU 613-732-3629. Depending on the situation, your vaccination history, and other risk factors, a public health official may advise you of the need to stay home from work or school, get tested, get preventive treatment or get vaccinated.
Immunization for children and youth
The best way you can protect yourself and others against measles is by getting the measles vaccine. This vaccine is combined with the vaccine for mumps and rubella and is known as the MMR vaccine. The MMR vaccine can also be combined with the varicella vaccine (MMR-V) for some individuals. MMR and MMR-V are very safe vaccines and very effective against measles. Two doses of measles vaccination is 97% effective at preventing infection.
Infants
Infants 6 to 11 months of age should get a dose if they are travelling to an area with increased measles activity.
Two additional doses of measles-containing vaccine must be administered after the child is 12 months old to ensure long lasting immunity to measles.
Children
Children should get two doses of the measles vaccine – a dose of MMR vaccine at 1 year of age and a dose of MMRV vaccine between 4 and 6 years of age (preferably prior to school entry).
Immunization for adults
The best way you can protect yourself and others against measles is by getting the measles vaccine. This vaccine is combined with the vaccine for mumps and rubella and is known as the MMR vaccine. MMR vaccine is very safe and very effective against measles.
Adults born in or after 1970 can receive 2 doses of MMR vaccine. This is particularly important for certain groups, including:
• healthcare workers
• child care workers
• school staff
• post-secondary students or staff
• military members
• those travelling to areas with increased measles activity
Adults born before 1970 are usually protected due to childhood measles infection. However, some remain susceptible and can be immunized with one dose if they are unsure if they had measles or the vaccine. A second dose of MMR vaccine is recommended regardless of birth year for the following groups:
• health care workers
• post-secondary students
• individuals planning to travel to areas with increased measles activity
• individuals for whom a second dose is recommended based on a healthcare providers clinical judgement
