Public health officials are investigating a case of red measles in Hamilton.

An adult has contracted a travel-related case of the measles, Hamilton Public Health Services said Friday. Officials say they are looking into exposure sites to identify where they might need to follow up with people.

“At this time, there is low risk of exposure in the Hamilton area,” the service said.

Here’s a list of symptoms:

  • Cough.
  • Runny nose.
  • Fever.
  • Red, watery eyes.

After about four days, a rash starts at the face and moves down the body. White spots may appear inside the mouth.

Measles spread easily to people who aren’t immune. Infants under a year of age, pregnant women and people with weakened immune systems can get particularly ill.

Complications include middle ear infections, pneumonia, croup and brain inflammation.

People who have had two doses of a measles vaccine, such as MMR or MMRV, are not at risk. Neither are people who have had the measles in the past.

Anyone planning to travel to the Philippines, Brazil or the Netherlands should make sure their immunizations are up to date. Anyone returning from those countries and experiencing symptoms should contact their family doctor.
