“Those on Feb. 2 and 3 that have been in those locations, they could be eligible for post-exposure prophylactics, especially if they are pregnant, immune compromised or under the age of one,” Medical Officer of Health Grazia Salvo said.

Only people who may have been exposed on Feb. 2 or Feb. 3 will be eligible for the preventative vaccine. Anyone who may have been exposed on Jan. 31 should still review their immunization history and call 811 for advice.

People who may have been in the areas listed, who were born after 1970 and have not already had measles or have not received two doses of the measles vaccine, may also be at risk for developing measles.

“If you were in those areas during that time, that the attack rate of measles is very high so you’re actually quite likely if you were in contact to develop disease,” Salvo said.

For someone who has had two doses of the vaccine, Salvo said there is next to no risk.

Anyone who thinks they may have been affected is encouraged to monitor themselves for symptoms. If symptoms do develop, AHS says to stay home and call Health Link 811 before visiting any healthcare facility or provider.

Symptoms of measles include:

Fever of 38.3 C or higher

Cough, running nose and/or red eyes

And a red, blotchy rash that appears three to seven days after the fever starts, beginning behind the ears and on the face and spreading down to the body and then to the arms and the legs

In Alberta, the measles vaccine is available free of charge through Alberta’s immunization program. Children typically receive their first dose of measles vaccine at 12 months and their second dose between the ages of four and six.

Salvo couldn’t say whether the person in question was vaccinated against measles, but did say not everyone can receive the vaccine.
