Hamilton Public Health is expanding its warning for measles exposure sites in the city.

On Monday afternoon, public health issued a warning that Blue Line Taxi riders could have been exposed to the virus:

Anyone who travelled in a Blue Line Taxi on the following dates is urged to contact Public Health Services:

  • Monday August 19 between 10 a.m. and noon or 3 p.m. to 5 p.m.
  • Thursday, August 22 between 10 a.m. and 2 p.m.

As well, in a statement released on Saturday, the city said that individuals who visited any of the following locations might have been exposed too:

  • Jackson Square (2 King St W) on Aug. 18 from 9 a.m. to 2 p.m.
  • Harvest Moon restaurant (80 James St North), Aug. 19 from 4 p.m. to 8 p.m.
  • Crowne Plaza hotel (150 King Street East) from Aug. 18 to 22 (elevators and Saffron Mediterranean Restaurant and Bar)

Anyone who visited those locations during the specified times who has not had two doses of a measles vaccine, or who has not had the measles in the past, is asked to call Public Health Services at 905-546-2063.

Symptoms include coughing, runny nose, rash, fever

The measles scare is travel related, officials say. The condition often starts with cold-like signs and symptoms, such as coughing, a runny nose, red, watery, eyes and a fever.

After about four days, infected individuals develop a telltale rash, which usually begins on the face and then moves down the body.

"Red measles is highly contagious to those who are susceptible from the beginning of the illness until four days after the rash first appears," said Dr. Ninh Tran, the city's associate medical officer of health.

"To avoid spreading illness to others it's important that ill individuals stay home."

The city advises people who think they have the measles and need to see a health professional to call ahead before leaving home.

In June, the Halton Region Health Department reported three confirmed measles cases in Burlington. All three cases were children from the same family. They are believed to have come into contact with the virus while travelling outside Ontario.
