The health department is urging anyone who attended a large event held at Niko’s R & R Supper Club in Marengo in mid-May to quarantine following a cluster of COVID-19 cases.

The McHenry County Department of Health (MCDH) said that people who visited the restaurant, located at 7509 South Grant Highway in Marengo, between May 14 to May 22 may have been exposed to COVID-19.

A complaint received by the health department on June 1 indicated that there was a potential exposure at a large event held on May 22 at the facility.

MCDH confirmed that patrons who were at the establishment on or after May 14 until May 22 had tested positive for the virus.

It is unclear how many people tested positive.

Those who were at the facility on May 22 should quarantine themselves until June 5 unless they develop symptoms, the health department said.

MCDH said they are working with the facility to ensure that the appropriate protocols are in place to stop the virus from spreading.

“We are continuing to investigate this event, but what matters most at this time is for anyone who visited the business during the dates of potential exposure to quarantine through June 5. If anyone begins to develop symptoms such as a cough, fever or chills, headache, new loss of taste or smell or muscle aches, please isolate and have yourself tested,” MCDH said in a statement.

The health department recommends that those who are not fully vaccinated should continue wearing masks in public settings.

Anyone who is 12 and older is eligible to receive a COVID-19 vaccine. Vaccine signup information can be found on the health department’s website here.
