Cold, flu: lifespan of the virus outside the body and how to avoid them

Cold and flu virus-laden droplets, when expelled by a sneeze or cough from an infected person, can remain infectious for several hours, depending on where they fall. Viruses generally remain active longer on stainless steel, plastic and similar hard surfaces than on fabric and other soft surfaces.

Other factors, such as the amount of virus deposited on a surface and the temperature and humidity of the environment, also determine the active longevity of cold and flu viruses outside the body.

The best way to catch a winter bug

It is possible to catch the flu or a cold after handling an object contaminated by someone who sneezed or coughed on it a few moments before. But physical contact with an infected person: such as shaking hands or inhaling droplets from a cough or sneeze, is the most common way these viruses spread.

The best way to avoid getting infected with a cold or flu virus is to wash your hands frequently with soap and water or an alcohol-based hand sanitizer. Also avoid touching your nose, mouth and eyes or biting your nails.

Top notch antiviral defenses

Also important, throughout the period of a flu epidemic for example, be sure to maintain your immune system and especially your antiviral defenses at the top. Physical activity, rest, healthy diet, cure of probiotics and inhalation of antiviral essential oils at home. Have a bottle of tea tree essential oil in your pocket throughout the winter. Soak a handkerchief with a few drops and breathe from time to time during the day, this will help you defend yourself against viruses.
