[ExI] china malaria

[William Flynn Wallace]

thanks Bill K - did go to Google and still don't understand it unless every
Chinese citizen is immune (which I doubt -if there is a 100% effective
preventative drug (which I doubt) that I don't know about, why doesn't WHO
get it to AFrica?) - even if they eradicated mosquitoes entirely, which
they didn't, they would still come in from neighboring countries in one way
or another.  bill w
