MARQUETTE — A case of measles has been confirmed in the Upper Peninsula.

According to the Marquette County Health Department, which announced the confirmed case Thursday, the individual was a Marquette county resident. MCHD is working closely with the Michigan Department of Health and Human Services to investigate the infection identified in Marquette, with the goal of preventing additional cases.

Because the virus can remain infectious in the air for up to two hours after an infected person leaves the area, individuals who were present at the following locations may have been exposed:

— Moonspun Wool, 219 West Washington St., Marquette, from 10 a.m. to 6 p.m. on Monday, May 19; from 10 a.m. to 6 p.m. on Tuesday, May 20; and from 10 a.m. to 2 p.m. on Wednesday, May 21.

— Marquette Food Co-op, 502 West Washington St., Marquette, on Tuesday, May 20, from 6 p.m. to 10 p.m.

— Midas, 2192 U.S. 41, Marquette, on Wednesday, May 21, from noon to 2:30 p.m.

Anyone who visited these locations during these times should contact MCHD at 906-475-9977 and monitor themselves for symptoms for 21 days. If any symptoms develop, stay away from others and call ahead to inform medical providers of your potential measles exposure before visiting a doctor, urgent care, or emergency room. Doing so allows providers to take precautions to avoid exposing others.

Symptoms of measles can include a high fever that may spike over 104 degrees Fahrenheit; cough; runny nose; red, watery eyes; tiny white sports on the inner cheeks, gums and roof of the mouth; and a rash that is red, raised and blotchy. The rash usually starts on the face before spreading to the trunk, arms and legs three to five days after symptoms begin.

Complications from measles may require hospitalization and can include pneumonia, brain swelling, or death.

“Measles is so contagious that ninety percent of non-immune people who are exposed to measles will become infected. In general, individuals with two appropriately spaced does of measles vaccine MMR are considered immune,” MCHD said in a press release.

Additionally, adults born before 1957 or who have evidence of prior measles illness are considered immune.

Due to the risk for community spread, anyone not fully vaccinated against measles is encouraged to get vaccinated as soon as possible. Contact your health care provider if you have questions regarding your status of immunity to measles or help locating vaccination records.

The first dose of the MMR vaccine is recommended for children at one year of age, with the second dose given between age 4 and 6. Those who were born after 1957 who have documentation of receiving at least one dose of MMR vaccine do not need a booster. Those who have not received the vaccine or who are unable to locate vaccination records are eligible to receive the vaccine.

MMR vaccines are available at local health departments, pharmacies and primary care physicians.
