The Perth District Health Unit are reminding people not to visit long-term care homes when they're sick, amid numerous outbreaks in the last three months.

Officials say between Dec. 1, 2014 and Feb. 26, 2015 there have been 20 outbreaks, including Norovirus and influenza A, at area homes.

There have even been instances of outbreaks of both illnesses at the same time and more thnan one outbreak in a home.

“Our citizens that live in long-term care homes are most often susceptible to complications and/or death from illnesses like influenza,” says Dr. Miriam Klassen, Medical Officer of Health. “We need to be very diligent about trying to keep their living environment free of illness.”

Visitors are asked to stay away at least 48 hours after the last symptoms of vomiting or diarrhea in the case of a gastrointestinal illness, and to not visit until respiratory symptoms are completely gone.

Peter Bolland, chair of the Perth County Facility Operators Group, says outbreaks are difficult for both residents and staff.

“Even with the best infection control practices, once a bug is in the building, it’s tough to stop the spread of illness. Residents get sick and are confined to their rooms, units are locked down to prevent co-mingling, group events are cancelled. Residents feel isolated and their quality of life is greatly affected."

They also leave facilities understaffed, leading to a vicious cycle, so Bolland says the best solution is prevention.
