- Well, since nearly everyone in my family had colds during the holidays :^(
- we had the following discussion endlessly:
-
- Should one discard one's old toothbrush upon contracting a cold in order to
- avoid reinfecting oneself?
-
- "Pro-" faction: The toothbrush is a repository for germs and mouth flora; it
- is never sterilized; thus it is a likely source of reinfection & (especially
- when ill) it should be thrown out & a new one obtained immediately. Continuing
- to use the same toothbrush is like eating over & over again with the same
- unwashed silverware. (yuk)
-
- "Con-" faction: Unless you share your toothbrush (yech), the only bugs on it
- are the ones already in/on your own body, to which you either (a) already have,
- or (b) are in the process of developing, immunity. Besides that, you can't
- "reinfect" yourself with your own cold virus, because the very thing that is
- making it go away is the fact that your body is developing antibodies to it.
- You won't catch the same virus again unless your immune system is compromised,
- though you might catch one of the other cold viruses, to which you have not
- developed antibodies. But you won't very likely get this from your own
- toothbrush; you'll get it from airborne droplets or skin contact with someone
- else who already has it. (My view; I was in the minority.)
-
- Anyone else spend the holidays debating this? What's the right answer?
