Information about the Norovirus

As a result of the enhanced visitor restrictions at the Miramichi Regional Hospital, the Miramichi Regional Health Authority has received a number in calls and inquiries from the public regarding Norovirus. The enhanced visitor restrictions were put in place due to an increase in the number of individuals experiencing gastrointestinal symptoms such as diarrhea and vomiting. This increase was noted in people presenting to the emergency department and within the hospital in both patients and staff. This precautionary measure was put in place to prevent the spread of this illness. To date, there have been four confirmed cases of Norovirus which is a virus that causes gastrointestinal symptoms such as vomiting and diarrhea.

Visitors to the Miramichi Regional Hospital will be limited to two members of the patient’s immediate family from 2-9 p.m. Patients will provide names of visitors and identification will be requested. Visitors who must visit or come to the hospital for scheduled medical appointments are asked to follow strict hand washing measures to help prevent spread of the virus.

Dr. Denis Allard, the Medical Officer of Health for the Miramichi region says that the best way to protect oneself from getting or spreading the infection to others is to practice good personal hygiene. He says more specifically to wash one’s hands thoroughly with soap and water after using the toilet or changing a diaper and also before preparing or eating food. When soap and water are not available, it is recommended that an alcohol hand rinse be used.
