EAST LANSING, Mich. (WOOD) — Those who recently visited a popular bar in East Lansing are being asked to self-quarantine after more than 30 people tested positive for COVID-19.

The Ingham County Health Department is urging anyone who visited Harper’s Pub in East Lansing between June 12 to June 20 to self-quarantine for 14 days since their visit and get tested for COVID-19.

At least 34 people, all but one of them Harper’s patrons, have tested positive for the virus. About half of the patients have a connection to Michigan State University, and all are aged between 18 and 23 years old, according to the health department.

The health department says it’s not possible to completely eliminate risk, and much of the responsibility falls on the public to follow safety guidelines like social distancing and wearing masks.

It also says Harper’s was following safety procedures for employees, capacity and table spacing. At this point, Harper’s has temporarily closed as it implements more safety protocols.

Anyone experiencing symptoms is urged to get tested. Information on where to find a testing site can be found on the state’s website.
