Health officials investigating 3 measles cases in Ottawa, Lanark County
Undervaccinated children exposed to outbreak will be kept out of school, says OPH
Ottawa health officials say they'll be keeping unvaccinated children and those with incomplete vaccinations who have been exposed to three measles cases out of school until they're fully protected.
The three related cases are in Ottawa and Lanark County and were confirmed on Sunday by an Ottawa Public Health spokeswoman to involve at least one child and one adult.
The cases are now being investigated by OPH and the Leeds, Grenville and Lanark District Health Unit.
All three were either unvaccinated or had not received all of their measles vaccines, the City of Ottawa said in a release.
Dr. Carolyn Pim, OPH's associate medical officer of health, told CBC News on Sunday that the measures were being taken to keep local schools free of the disease.
"We certainly may identify other schoolchildren, but we will deal with those on a one-on-one basis," said Pim.
"We have no particular schools in which there are cases of measles. We don't have any particular schools that we feel are at risk. But by excluding individuals that have been exposed, we're trying to prevent the introduction of any cases into those schools."
Symptoms include fever, cough, blotchy rash
The measles virus is spread through coughing and sneezing and can lead to ear infections, pneumonia, brain swelling or even death.
Common symptoms include fever, cough, runny nose or red eyes and a red blotchy rash that appears several days after the fever starts.
One of the locations where health officials say people may have been exposed to the measles virus is the Children's Hospital of Eastern Ontario, where Ryan Knuth's two-month-old son Theo recently spent five days after developing a fever.

OPH called Knuth on Friday to let him know that Theo — who is too young to be fully immunized against measles — may have been exposed to the measles virus.
Knuth told CBC News he felt "concern, anger [and] confusion" after getting that call. His son has now received immunoglobulin shots in the hopes the antibodies will offer additional protection, he said.
"If you decide not to vaccinate your child, it's affecting others. And it can and will affect others," Knuth said. Right now, my son is at home, at risk of severe complications — potentially even death — because of exposure to measles."
Measles vaccine 'very effective'
Health officials have not identified the ages of the three people who fell sick, how they might have contracted the virus, or why they were not fully immunized.
Those who have been exposed to measles and have been fully vaccinated, however, have an extremely low chance of becoming ill, Pim said.
"We've identified where the cases who've had measles went, and that certainly is where people may be at risk," said Pim.
"[But] if people are fully immunized, their risk is extremely low. The measles vaccine is very effective. If you've had two doses of vaccine it's virtually 100 per cent effective."
The last measles outbreak in Ottawa occurred in 2014, said Pim. Most of the cases seen in Ottawa are "related to international travel," she said.
The measles vaccination rate among local school-aged children is 98.4 per cent, said Pim, "which is really excellent."
If someone suspects they, or someone in their family, has the measles, they should contact their health care provider, health officials said. The public is reminded to call ahead before coming in.
