In a follow-up on the measles outbreak in Michigan, state health officials are now reporting 43 confirmed cases since mid-March.

To date, 40 cases have been reported in Oakland County, one in Wayne County and one in the City of Detroit. In addition, an international traveler was diagnosed with measles following a visit to Washtenaw County, during which time he was contagious.

Most cases were reported in adults.

Unvaccinated residents, or residents who are unsure of their vaccination status, should get vaccinated. Residents should contact their healthcare provider or local health department to receive vaccine. If symptoms develop, do not visit your doctor or emergency room unless you call ahead so they can take precautions to prevent exposure to other individuals.

The measles vaccine is highly effective and very safe. A single dose of measles vaccine protects about 95 percent of children, but after two doses, almost 100 percent are immune. You cannot get measles from the vaccine. It can be effective within 72 hours of exposure to prevent illness.
