Measles Outbreak in Michigan

Michigan's measles outbreak is part of a national trend, with over 800 cases reported across the U.S. in the first four months of 2025, surpassing the total number for all of 2024. 

Measles is a highly contagious viral respiratory illness that spreads through the air when an infected person coughs or sneezes. The virus can survive on surfaces for up to 2 hours. 

Incubation Period: symptoms usually appear 11-12 days after exposure. 

Early symptoms: Mild fever, sore throat, cough, runny nose and red, watery eyes. 

Koplik Spots: Tiny white spots may appear inside the mouth 2-3 days following onset of symptoms

Rash: A red, blotchy rash typically starts on the face and spreads down the body appearing 3-5 days following the start of the illness. The fever typically becomes much higher (104-105) during this phase of the illness

The measles rash may last about 7 days before gradually fading from the face first, then the rest of the body. As other symptoms of the illness resolve the skin may darken and peel. 

Individuals are contagious from four days before the rash to four days after the rash appears. 

While most people recover fully, measles can lead to serious health issures especially in children younger than 5 years, pregnant women and immunocompromised persons.

Possible severe complications include Pneumonia, Encephalitis (swelling of the brain which can lead to seizures and permanent brain damage,) and death. 

What to do if you have a suspected case:

1. Contact your healthcare provider if you think you or your child may have been exposed to measles or if you or your child has a rash that looks like measles. 

2.  Review your vaccination status - your provider can help determine if you're immune based on your vaccination records or may recommend a booster dose of vaccine. 

5. Isolate. To protect others, stay home and avoid public places until your healthcare provider advises it's safe to return. 

Prevention of disease is possible with the MMR vaccine. This vaccine is 97% effective in preventing measles. Children receive two doses: the first at 12-15 months and the second at 4-6 years. Ensuring up to date vaccination is crucial, especially amid rising cases.
