A second employee at the Covered Bridge Restaurant in Contoocook has tested positive for Hepatitis A, the Concord Monitor reported.
Health officials involved are currently advising customers who have yet to be vaccinated for the virus to do so as soon as possible.
The officials confirmed that there have been no other reported cases.
"There is a low risk of exposure. Between 100 and 200 people who visited the restaurant on August 13 or 20 may have come in contact with the virus," said Jose Montero, director of the state Division of Public Health Services.
Montero recommended that anyone who ate at the restaurant on August 20 be vaccinated by Tuesday at the least.
This timeframe is given because the vaccination will no longer be effective if it is not done by then.
On the other hand, "those who at the restaurant on August 13 but have not yet been vaccinated should watch out for possible infections including fatigue, fever, nausea, vomiting, dark or discolored urine and gray-colored stool," Montero further stated.
Donna Walter, the person who owns the restaurant told Concord Monitor that the two employees are friends.
The second patient was taking care of the firsts as the illness progressed.
