Also raising some concern are reports that the CDC screened only for six viruses common to this country when confronted with the initial victims. The scientists did not test for several that have been linked to foreign epidemics or germ warfare. But Harvard's Pollack says public health officials did nothing wrong in their response to the scare. If anything, Pollack says, more resources devoted to surveillance of mosquitoes and mosquito-borne viruses would help promote quick and early responses to future outbreaks. Over last couple of decades, there has been an obvious reduction in resources devoted to surveillance of this kind.
Fewer places can monitor mosquito populations.
