Preventing Transmission of Viruses and Bacteria

Certain viruses and bacteria are transmitted through close contact with people. Several situations present such contact, including the following:

  • Living or working with other people
  • Giving care to a person
  • Frequenting public areas

There are certain measures you can take in order to prevent the transmission of viruses and bacteria.

Measures to Take


The best way to protect yourself and others is through vaccination. When a vaccine against an infection or a disease is available, get it.

Hygiene Measures

  • Avoid touching your nose, eyes and mouth. These are entry points for viruses and bacteria
  • Avoid contact with people that are sick or that may be contagious. Do not get close to them and do not touch objects which they have used, such as utensils for instance
  • Take the habit of cleaning your surroundings regularly. Clean counters, sinks and other surfaces that you touch often with your hands. Cleaning is very effective in killing viruses, which may live up to 2 days on hard surfaces
    • Clean with soap and water or use domestic detergents
    • For toilets and sinks, use a detergent that contains bleach. This type of detergent cleans and disinfects at the same time. If you do not have detergent with bleach, first clean toilets and sinks with regular detergent. To disinfect, prepare a mixture by diluting one part bleach with 50 parts of cold water. Apply the mixture and let stand 10 minutes.
