Hepatitis A Confirmed At Pine Knob In Oakland County

Pontiac, MI - Oakland County Health Division is providing an update on the suspected case of hepatitis A associated with the Ivy Lounge at Pine Knob Music Theatre in Clarkston: the case was confirmed by MDHHS Laboratory.

The Health Division advises all season members, their guests and staff who consumed food at the Ivy Lounge between Aug. 26 – Sept. 8 to monitor for symptoms, and if unvaccinated for hepatitis A, to get vaccinated as soon as possible. 

“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."

For people who were possibly exposed to hepatitis A from Aug. 26 - Sept. 8 at the Ivy Lounge, below is a breakdown of exposure dates and recommended actions: 

All individuals potentially exposed should watch for hepatitis A symptoms and contact your healthcare provider if you become ill to report you have a known hepatitis A exposure. 

Hepatitis A is an infection of the liver caused by a virus. The virus is shed in feces and is most commonly spread from person to person by contaminated hands. Symptoms include sudden abdominal pain, fatigue, diarrhea, nausea, headache, dark urine, and vomiting followed by yellowing of the skin and eyes. Symptoms may appear from two to six weeks after exposure, with the average time being about one month. In rare cases of hepatitis A infection, those with a pre-existing severe illness or a compromised immune system can progress to liver failure.  

To reduce the risk of contracting hepatitis A:

• Wash hands frequently, especially after using the bathroom, changing diapers, and before preparing and eating food. Rub hands vigorously with soap and warm running water for at least 20 seconds. Handwashing is essential and one of the most effective ways to prevent the spread of infection.
• Clean and disinfect all surface areas if someone in the household or workplace has symptoms, especially areas such as toilets, sinks, trashcans, doorknobs, and faucet handles.
• Do not prepare food if you have symptoms and refrain from food preparation for at least three days after symptoms have ended, or two weeks after onset of clinical symptoms, whichever is longer.
• Get the hepatitis A vaccine. It is available through some health care providers, Health Division offices and many pharmacies. Call ahead to ensure your health care provider or pharmacy has the vaccine available.

Health Division offices are located at the following addresses:

• North Oakland Health Center, 1200 N. Telegraph Road, Building 34 East, Pontiac
• South Oakland Health Center, 27725 Greenfield Road, Southfield
