Over 5,000 trap records document mosquito collection and West Nile Virus testing across Chicago wards and community areas. The Chicago Department of Public Health Environmental Health program gathers this data through its environmental surveillance program, with records updated through 2024.
A filtered view excludes trap records with zero female Culex mosquitoes; the raw dataset includes these zero-collection records which must be filtered out for analysis.
