Cryptosporidium oocysts are common and widespread in
ambient water and can persist for months in this environment. Studies conducted
in various locations have noted an increase in cryptosporidiosis during the warm
and rainy season. We are conducting a meta-analysis to examine how an increase
in rotavirus and cryptosporidiosis relates to precipitation and ambient temperature worldwide.
We are investigating the potential of using remote sensing data as a proxy for
exposure to borne infection globally. The source and occurrence of
Cryptosporidium in watersheds has been characterized, although continued
improvements in monitoring methods and analytical techniques would increase our
understanding of these issues. We are currently studying such methods that can
lead to discovering specific contamination sources that will ultimately
contribute to public health protection.
