The Grey-Bruce Health Unit wants you to stay home if you're feeling sick.
Public Health Nurse Amanda McManaman says the holidays are a busy and stressful time, and it may leave you feeling under the weather.
And she says as much as you want to get out and visit friends and family, it's important to think of others if you're not feeling well.
McManaman says this is especially important if you're going to visit people in hospitals, nursing homes or retirement homes.
She says because of the nature of those facilities, there are more people around who are already sick or more vulnerable to getting sick.
She says sicknesses can spread a lot faster, and it could have a devastating impact.
If there is an outbreak, for example, McManaman says there could be a staff shortage.
She says it's important to pay attention to how your body feels. If you don't feel in the festive spirit, she says it's okay to take a rain check.
Even if you are feeling well, McManaman says to make sure you follow hand washing practices and use hand sanitizer to prevent the spread of anything you might be carrying, and to protect yourself against any illness.
If you are travelling to visit someone and they are in a facility, she says a good idea is to call ahead to make sure they're not dealing with an outbreak and that visiting is still okay.
