A Starbucks employee tested positive for hepatitis A, possibly exposing thousands of customers to the virus - CNN

The hepatitis A exposure encompasses anyone who visited the Starbucks at 1490 Blackwood Clementon Road on November 4, 5, 6, 11, 12 and 13, according to county spokesman Dan Keashen.

The Camden County Health Department was notified of the incident on Wednesday and immediately shut down the Gloucester Township Starbucks location, Keashen told CNN.

People who frequented that Starbucks and aren't vaccinated for the hepatitis A are advised to receive the vaccine "as soon as possible but no later than 14 days after contact," the health department said in a news release on Friday.

"The county health department has been working closely with the patient and the staff at the Starbucks to address the situation," Camden County Health Officer Paschal Nwako said in a news release.

"Our highest priority is ensuring everyone involved remains safe and healthy.

We encourage anyone who may believe they were exposed to get vaccinated against hepatitis A by calling the county health department or your primary care physician."

Public health employees provided 17 hepatitis A vaccines to Starbucks employees on Thursday and set up a nearby pop-up vaccine clinic Friday and Saturday, Keashen said.

So far, 800 vaccines have been administered, marking the largest hepatitis A vaccine effort in the state's history, according to Keashen.

"Starbucks says that that location is busy, as most are," Keashen said.
