There are 122 confirmed flu cases in the Windsor area, with 36 people being hospitalized, and as many as five confirmed deaths.
Windsor Regional Hospital CEO David Musyj (Moo-SHAY) says only about 50 to 60 per cent of staff there have received a flu shot and that's far too low.
He says there may have been some apathy among hospital staff about getting the shot, but the increasing number of flu cases this season is prompting some to change their minds.
The hospital has imposed visitor restrictions similar to those put in place during the 2003 SARS outbreak.
That means visitors must wear masks and there's a limit on the number of visitors per patient in most units.
Officials say many of those diagnosed with influenza this season have the H1N1 strain of the flu.
It's not too late to get a flu shot and Windsor officials say about 2,000 doses are available at local walk-in clinics and pharmacies, with more expected to arrive this week.
