    Hi Guys, excellent podcast for IT business analyst. Just wondering about flu/cold transmission in the household. Would sharing toothpaste be a valid way to transmit. I figure it would ie mouth to brush, brush to toothpaste tube, next person has toothpaste tube to brush, brush to mouth. or it this paranoia :). or does tooth paste kill it? interesting đŸ™‚


    • It's a good question – whether toothpaste tubes spread influenza. It
      depends on how much virus would be present; my feeling is that levels
      would be too low. From saliva to toothbrush to tube; plus the time
      sitting on the toothbrush until the next contact with tube, would
      result in low amounts of virus that would not effectively transmit. As
      for toothpaste – I'm looking at a tube of Crest and the only
      ingredient listed is 0.243% sodium fluoride, not known to be an
      influenza antiviral. The other components are likely to be flavors and
      fillers. Bottom line: I don't worry about toothpaste as a way of
      transmitting influenza.
