My friend believes that viruses need moister. He believes that if he holds his breath for thirty seconds after someone coughs that all the moister in the cough will dry up and the viruses will die.
My friend also believes that he can prevent himself from contract a human version of the H5N1 bird flu viruses by wearing a Sears dust mask.
I'm no biologist, but I don't think that viruses contain any moister. I would guess that their survival outside a host is not determined by the availability of moister.
It is also my view that the holes in the Sears dust mask are 100,000 times larger than a flu viruses, and thus, will be very ineffective at preventing the spread of the disease.
Is my friend 100% totally wrong on this one? I could believe that the Sears dust mask is 01% affective, but I don't really think he understands much about viruses.
