Fraser Health says visitor from Ontario is the latest case of measles in B.C.

Health authorities in British Columbia have confirmed another new case of measles infection in the province, this time with a visitor from Ontario.

Fraser Health says the visitor travelled to Vancouver and Chilliwack on April 20, and doctors and health workers are "following up directly" with people known to have been exposed.

In addition, Fraser Health is warning anyone who flew fromToronto to Vancouver on April 20 on Air Canada Flight 2105, which departed at 8:38 a.m. and arrived at 10:09 a.m., to monitor for symptoms.

The health authority says the infected visitor also visited Vancouver International Airport's domestic terminal as well as the Chilliwack Coliseum on that day, and the unidentified person also stayed at the Coast Chilliwack Hotel until April 25.

Fraser Health says most Canadians are immune to measlesdue to either prior immunization or infection.

Those who are not immune may see symptoms such as fever, dry cough, runny nose and red eyes, as well as a rash that spreads to the entire body a few days after initial symptoms emerge.

Those who develop symptoms are asked to stay home and contact health authorities to discuss treatment advice to prevent further spread.
