Should a local outbreak be detected, the CDC will swoop in (if required) and assist with all aspects of damage limitation. Experts will help train local medical professionals, offer support for diagnosis and help secure supplies of clean blood. Should the situation worsen and transmission increases, officials will help spray the local area with pesticides and plan for dealing with babies born with microcephaly. Having plans in place to handle outbreaks is all the more valuable now that the CDC has confirmed the occurrence of Zika-linked birth defects in the United States. According to the Washington Post, three women delivered babies with said defects, while three more terminated their pregnancies because the infants suffered Zika-related brain damage.

Hawaii, as well as states in the south and southwest of the continental US are on higher alert as they play host to the largest mosquito populations.

But, as Stat explains, prevention is better than cure, and residents in certain states are being advised to dump standing water and take other general precautions.
