The mosquito-borne disease surveillance program is made up of four parts. The first part is the sentinel chicken surveillance. This portion uses the appearance of mosquito-borne disease in chickens to monitor the transmission of disease among the disease’s reservoir host, birds. The second part of the program is specialized adult mosquito trapping. This trapping is performed with CDC light traps to monitor the level of vector mosquito, Culex nigripalpus. The third part is the analysis of the collected vector mosquito through RT_PCR for the presence of viral RNA. This data indicates the presence of infected or potentially infected mosquitoes. The final part is human investigation. Human case investigation involves determining when and where a disease was contracted. The disease contraction could be outside the neighborhood of the victim or outside the country.
