	Someone recently asked about smallpox virus.  This virus has
no reservoir in nature except man.  Wipe out all disease- there are
no persistent infections with smallpox- and you wipe out the virus,
pure and simple.  Thus, the only smallpox virus left is in the 
freezers at CDC in Washington and somewhere in Russia.  There is
currently a debate about whether it is wise to destroy these stocks
given that unforeseen circumstances might warrant further laboratroy
study of this agent.
