Measles
What is measles? |
|
Measles is a very contagious respiratory virus that can spread easily through the air when someone with measles breathes, coughs, sneezes or talks. The virus can stay in the air or on surfaces for up to two hours after an infected person has left the area. People can become infected if they breathe the contaminated air or touch the infected surfaces, then touch their eyes, nose, or mouth. |
What are the symptoms of measles? |
|
Symptoms of measles can take seven to 21 days to develop after exposure (usually 10 to 12 days). The first symptoms to appear are:
Two to three days after developing the first symptoms, small white spots may appear in the inside of the mouth and throat (Koplik spots). About three to seven days after symptoms begin, a rash develops on the face then spreads to the rest of the body. This rash can last four to seven days. |
What should I do if I have symptoms? |
|
If you have symptoms of measles, isolate at home and avoid contact with others. Call before visiting a health care provider, clinic or hospital so they can prepare for your visit and prevent exposing others. Stay home from work, school, childcare and other public activities for four days after the onset of the rash. Only return once well enough to participate in activities. Note: Guidelines for absence may differ for healthcare workers. Follow the direction of your healthcare provider, public health case manager, or occupational health at your workplace. If you have been tested for measles please see Measles Testing: A Quick Guide for Patients. |
How long is someone with Measles contagious? |
|
Someone with Measles can spread the virus from four days before, to four days after the first sign of a rash. |
Treatment |
|
There is no treatment for measles. Drink plenty of fluids, get lots of rest, and seek medical attention if symptoms are not manageable at home. |
Long-term complications |
|
Many people fully recover from measles within two to three weeks, but some people will have complications that can include:
Complications for people who get Measles while pregnant can include:
|
If I've already had measles, can I get it again? |
|
Most likely not. Being infected with Measles generally gives you lifelong immunity to the virus. |
Vaccination
Check your immunization record to make sure you're up-to-date with your MMR vaccine, and get caught up on any outstanding doses based on the guidance below.
What are your recommendations for receiving the MMR vaccine? |
||||||||
|
||||||||
I've had two doses, but they were a long time ago. Do I need a booster dose? |
||||||||
|
No, people who have received two doses of the MMR vaccine are considered protected for life and never need a booster dose. |
||||||||
What if I can't find my vaccine record? |
||||||||
|
If you, your healthcare provider and the Health Unit are not able to retrieve your vaccination record, you are considered unimmunized and can be started on an age-appropriate routine immunization schedule as per the publicly funded immunization schedule. Even if you received a vaccine in the past, it's safe to get additional doses of the MMR vaccine. |
||||||||
Will you be holding vaccine clinics? |
||||||||
|
We are continuing to monitor and assess the situation and cannot speculate on the availability of mass vaccination clinics at this time. Should we determine vaccine clinics are required, we will share details as they become available.
|
||||||||
How can I book a vaccine appointment? |
||||||||
|
To book a vaccine appointment with us, email vpd@healthunit.ca or call 1-800-563-2808, ext. 5252. Your patience is appreciated as we anticipate a high volume of calls.

Our hours of operation are Monday to Friday, 8:30 a.m. to 4:30 p.m. You can also contact your health care provider to request an appointment. |
||||||||
How long does it take for the vaccine to work in your body? |
||||||||
| The body needs time to produce protective antibodies in response to the vaccine. People are usually fully protected after about two week post-vaccination. | ||||||||
How effective is the measles vaccine? |
||||||||
| Short answer: very! Two doses of the measles vaccine are about 97% effective at preventing measles if exposed to the virus. One dose is about 93% effective.
