If you've done any traveling from certain areas recently, the Windsor-Essex County Health Unit says you may have been exposed to the measles.
On Friday afternoon, the health unit issued a warning.
The locations discussed are as follows.
Flight Lufthansa LH1661 from Timisoara Traian Vuia International Airport, Romania, to Munich Airport, Germany, on January 11.
Flight Air Canada LH6790 from Munich Airport, Germany, to Pearson International Airport, Toronto, on January 11.
Westbound Highway 401, at the ON Route location in West Lorne, on January 11, from approximately 8:30 p.m. to 10:40 p.m.
A&R Medical Centre, located at 1800 Tecumseh West in Windsor, on January 15, from approximately 1:00 p.m. to 3:30 p.m.
The health unit said those who may have been exposed should monitor for symptoms that may appear from seven to 21 days after exposure.
"Symptoms can include a fever, runny nose, cough, drowsiness, irritability, and red eyes," read the warning from the health unit. "A red rash appears on the face three to seven days after the start of the above symptoms. The rash may start from the face and progress down the body. If you develop these symptoms, contact your healthcare provider."
The health unit says the measles virus is easily spread through the air when an infected person coughs, sneezes, or talks, and another person breathes in the virus particles, which can remain in the air for up to two hours. It can also be transmitted through direct contact with facial secretions.
"Anyone who has not had measles or has not been vaccinated against measles can become sick. Please contact your healthcare provider to confirm whether you are immune to measles," read the notice. "Infants less than 12 months of age, pregnant people, and immune-compromised individuals who have been exposed to measles should consult with their health care provider for individual medical advice."
Complete information on the measles virus is available from your healthcare provider or through the health unit.
