Measles Cases Rising Dramatically in U.S., Tied to International Travel

March 21, 2024

With the recent increase in measles cases in the United States, Minnesota physicians are warned to be on the lookout for patients presenting with rash, fever, and cough, coryza, or conjunctivitis, and to isolate these possible measles cases. 

More than 90% of the U.S. cases are related to international travel. In just over a month, the U.S. cases have increased from nine to 58 as of March 14. Minnesota has already had three cases reported in 2024, all related to international travel.   

Minnesota physicians are asked to collect specimens as soon as possible after rash onset and obtain specimens for PCR testing. Then, immediately report suspected and confirmed cases to the Minnesota Department of Health at 651-201-5414.

MDH is stressing that it is important to assess MMR vaccination status at every clinic visit and to recall those who have previously refused MMR vaccine for their child. The current measles situation is an opportunity to restart conversations with patients about the importance of vaccination. Many parents just need reassurance that the MMR vaccine is safe and will protect their child. For parents or patients who decline MMR for themselves or their children, counsel them that they could be excluded from childcare/school/work for 21 days or longer if exposed to measles.   

Keep in mind that the percentage of 2-year-olds in Minnesota receiving at least one dose of MMR vaccine by 24 months has declined from 83.8% in 2019 (pre-pandemic) to 78.7% in 2023.    

Also, be aware that newcomers to the U.S. and Minnesota may not have received an MMR vaccine.   

Partner with the Minnesota Immunization Information Connection (MIIC) to take part in a new texting initiative to remind or recall patients in need of MMR vaccine. Email health.miictexting@state.mn.us to sign-up or get more information about the program.
