Oakland County health officials are recommending that anyone who attended or worked at the Michigan Renaissance Festival over Labor Day weekend be vaccinated for hepatitis A.

The "Oakland County Health Division was alerted this evening (Sept. 13) that an attendee of the Michigan Renaissance Festival in Holly has a confirmed case of hepatitis A and was ill while attending the festival on September 1," the health department said. "It is strongly recommended that those attending and working the festival on Sept. 1 and Sept. 2 get a hepatitis A vaccine by Saturday, Sept. 15, if they have not been vaccinated."

Health Division Officer Leigh-Anne Stafford said a vaccination received within 14 days of contact can prevent the disease.

"Attendees unable to get vaccinated by Sept. 15 are advised to be aware of hepatitis A symptoms, such as sudden abdominal pain, diarrhea, nausea, headache, dark urine and/or vomiting often followed by yellowing of the skin and eyes (jaundice)," the health department said. "Symptoms may appear from 14-50 days after exposure, but average about one month."

Hepatits A is a "highly contagious" viral infection that attacks the liver and is usually spread through contact with contaminated food, water or someone with the virus, according to the Centers for Disease Control (CDC).

"It can range from a mild illness lasting a few weeks to a severe illness lasting several months," the CDC says. "Although rare, hepatitis A can cause death in some people."
