Wayne County health officials report that a worker at the Token Lounge in Westland has been diagnosed with hepatitis A,

The club at 28949 Joy Road remains open for business, but people who drank beverages there between Nov. 20 and Dec. 4 are encouraged to watch for symptoms of the disease.

Hepatitis A has been sweeping across southeast Michigan since August 2016 in what public health officials said is one of the largest outbreaks to occur in the U.S. since a vaccine was widely introduced two decades ago.

Nearly 600 cases have been reported in the state. Twenty people have died.

The Token Lounge was inspected Dec. 13 and is working with health officials in their investigation, according to the Wayne County Department of Health, Veterans and Community Wellness. The health department is offering vaccines to employees.

Hepatitis A attacks the liver and causes symptoms such as abdominal pain, nausea, vomiting, diarrhea, dark urine, clay-colored stool, fever, chills, and yellow skin and eyes (jaundice). Symptoms occur between 15 and 50 days after exposure and can last for several weeks to months. The disease can be fatal.

Officials say the best way to avoid the spread of hepatitis A is to get vaccinated. People should always wash their hands with soap and water after using the bathroom or changing a diaper, as well as during food preparation and before eating food.

Additionally, people should avoid consuming under cooked or raw shellfish, and should not prepare food for others if they are sick.

County officials are encouraging all residents to get vaccinated. For people without insurance coverage, a vaccine is available at the Wayne County Health Department Clinic at 33030 Van Born Road in Wayne.
