Preventing Infections

Protect yourself and others with these simple steps.


If you have questions about preventing infections and you would like to speak with a health professional, call the Infectious Disease Control Team at 519-663-5317.

  • Clean your hands
    Frequently clean your hands using soap and water or alcohol-based hand sanitizers. Alcohol-based hand sanitizers should contain minimum 60% alcohol. Hands should be cleaned after using the washroom, after changing diapers, after shaking hands, touching animals, touching objects around you and before preparing and eating food.
  • Clean surfaces
    Frequently clean and disinfect surfaces that are touched a lot like doorknobs, keyboards, counter tops, sink taps, etc. 
  • Cover your cough (PDF)
    Coughing and sneezing can spread germs to others. Cough or sneeze into a tissue and throw it away. If you don’t have a tissue, cough or sneeze into your sleeve. Always clean your hands after coughing or sneezing,
  • Stay home if you are sick.
    Sick people who go to work, school and other public places can spread their illnesses to others. Staying home is important to help reduce the spread of disease. Return to work or school one day after you are symptom free. If you have diarrhea or vomiting, do not prepare food for others until it has been at least 48 hours since the last time you had diarrhea or vomiting.
  • Handle Food safely
    Germs that you cannot see, taste or smell can make you sick if food is not handled or cooked properly. Most cases of food poisoning can be prevented with safe food handling.
  • Get Immunized (shots)
    Vaccines (shots) are one of the most important ways to prevent infections. They protect both you and the community. Getting the right shot at the right time is important. Talk to your health care provider or a public health nurse to see what vaccines are right for you and your family.
