Windsor-Essex health unit launches new measles exposure self-assessment tool

The Windsor-Essex County Health Unit (WECHU) has launched a new self-assessment tool for people who might have been exposed to measles.

The tool will help those who might have been exposed to measles to figure out what to do next, WECHU said

The Windsor-Essex County Health Unit (WECHU) has launched a new self-assessment tool for people who might have been exposed to measles.

The tool guides people through a series of questions to determine the next steps they should take.

"The risk assessment tool will let the user know if they are eligible for additional vaccination or treatment options, which can make the difference between mild and severe illness for those at risk of infection," the health unit said in a news release issued Wednesday.

"It will make further recommendations around contacting the health unit or monitoring for symptoms for seven to 21 days."

The launch of the new tool comes as the health unit has routinely announced new sites of possible exposure to measles, which has been spreading in southern Ontario.

Twenty-three people in the county are currently infected, according to data on the health unit's website. 

For many individuals, the symptoms of measles can be managed at home but those most at-risk need to take additional steps, the health unit said.

"As a result of our region's high vaccination rates, the next steps for those exposed to the virus are simple for most," said Medical Officer of Health Dr. Mehdi Aloosh. "Things get more complex for those who are unimmunized or under immunized.

"This new tool will be an asset to those who are unsure if they should be staying home, calling our office, or moving along with their day to day lives after being exposed to measles in a community setting. Vaccinated or not, this will provide clear guidance to those who have been exposed and [are] looking for next steps."

The online risk assessment tool is available on the WECHU's measles exposure webpage.

Vaccination is the most effective way to prevent measles, the health unit said.

Those born before 1970 and those who have had two doses of measles vaccine are considered to be immune to the disease.

Anyone who is unsure of their vaccine status or has not received two doses should speak to a healthcare provider, the health unit said.

Those without a healthcare provider can contact Virtual Urgent Care or Health811.

The health unit lists possible public exposure locations on its measles exposure locations page.
