So What Do You Think – Answer True or False… Flu Viruses Live Longer on Surfaces Than Cold Viruses

Most people know that cold and flu viruses can contaminate doorknobs, handrails, elevator buttons and other surfaces.
Most people know that cold and flu viruses can contaminate doorknobs, handrails, elevator buttons and other surfaces.

Studies have found that the survival time for both kinds of viruses varies greatly, from a few seconds to 48+ hours. The reasons have to do with a number of factors, including the type of surface, humidity and temperature.

  • For example, cold and flu viruses survive longer on inanimate surfaces that are nonporous, like metal, plastic and wood, and less on porous surfaces, like clothing, paper and tissue.
  • Most flu viruses can live one to two days on nonporous surfaces, and 8 to 12 hours on porous surfaces.
  • A rather unnerving 2006 study found that avian influenza seemed particularly hardy, surviving as long as six days on some surfaces. (The study noted how long the virus was viable in avian feces. http://www.who.int/mediacentre/factsheets/avian_influenza/en/)

On human skin, cold and flu viruses generally last less than a few minutes, but that’s plenty of time for people to infect themselves.  Studies show that most people touch their hands to their face, eyes or mouth many times — enough to cause infection.

So the long-winded answer is…flu viruses tend to survive longer than cold viruses.  This goes back to the importance of good hand hygiene and not touching your face with your hands…after all, you likely have no idea whats on them!
