Thousands of concertgoers may have been exposed to hepatitis A during nine shows held at the Pine Knob Music Theatre in Clarkston, according to the Oakland County Health Division.
The health department recommends that anyone who visited the Ivy Lounge while attending a concert at Pine Knob between Aug. 26 and Sept. 8, monitor themselves for symptoms, and if unvaccinated for hepatitis A, get vaccinated as soon as possible.
For those exposed at the Jason Aldean concert on Sept. 8, Saturday, Sept. 23 is the last day to be vaccinated, according to the health department.
“The window for vaccination to help prevent illness from hepatitis A is through tomorrow for those individuals who attended the Jason Aldean concert and ate at the Ivy Lounge,” said Dr. Russell Faust, Oakland County medical director. “For anyone who is not vaccinated for hepatitis A, we encourage getting vaccination to protect against future exposures.”
Hepatitis A is a highly contagious liver infection caused by a virus. It is most commonly spread from person to person by food or water contaminated with feces from an infected person. Symptoms may appear from two to six weeks after exposure, and can include sudden abdominal pain, fatigue, diarrhea, nausea, headache, dark urine, and vomiting followed by yellowing of the skin and eyes. In rare cases of hepatitis A infection, those with a pre-existing severe illness or a compromised immune system can progress to liver failure.
The affected concerts include Lynyrd Skynyrd (Aug. 26), Arctic Monkeys (Aug. 29, Foreigner (Aug. 30), Disturbed (Sept. 1), Beck and Phoenix (Sept. 2), Pentatonix (Sept. 3), Rob Zombie (Sept. 5), Smashing Pumpkins (Sept. 6), and Jason Aldean (Sept. 8).
All individuals potentially exposed should watch for symptoms and contact their healthcare provider if they become ill to report the possible exposure.
