Suitability mapping methods are helpful for quickly
identifying the places likely to have the greatest
risk for various outbreaks so that resources
can be allocated to the locations with the most
urgent need for health education, vector control,
and other prevention and control interventions. The
maps for Zika can be efficiently updated using PA
Tools as more scientific discoveries about the population
and environmental conditions most suitable
for Zika are made. For example, recent evidence
has shown that A. aegypti are able to overwinter
as far north as Washington, D.C., and if this observation
is validated in other northern locations the
model can be adjusted to have a lower minimum
temperature threshhold
