The South Bruce Grey Health Centre is taking precautions at all of its hospitals to stop the spread of the flu.
All hospitals in Kincardine, Chesley, Walkerton and Durham will allow inpatients only one visitor at a time from 2 PM to 4 PM.
Officials say the reason is in an increase in flu like cases all over Bruce and Grey Counties.
No visitors will be allowed at the Family Birthing Centre in Walkerton because of the greater risk H1N1 poses to pregnant women and new mothers.
All of the hospitals will remain open for emergency and outpatient clinic visits.
