Fraser Health issued a warning after a person with measles reportedly visited a New Westminster pool last week.
Officials say that anyone at the Moody Park outdoor pool on Sunday, August 19 between 1:30 pm and 4:30 pm PT may be exposed to the virus.
Measles is a serious disease caused by a virus in the air that is spread by breathing, coughing or sneezing. It can be very contagious.
Fraser Health says that symptoms are fever, cough, runny nose, and red and inflamed eyes that start a week to two weeks after exposure. This is followed by a rash that starts on the face and neck and spreads to the rest of the body.
Vaccines offer protection
Fraser Health says that you are protected against the disease if you were born before 1970 and have previously had measles. You are also protected if you were born after 1970 and had two doses of the measles vaccine.
If you are not protected, Fraser Health says that symptoms can not occur until September 9, 2018. If measles complaints develop, stay at home and stay away from others and contact public health.
