A communicable disease, also known as an infectious disease, is an illness transmitted through direct contact with an infected individual or animal – or indirectly through contact with a vector such as a mosquito, tick or plant, with blood or bodily fluids, or by breathing in an airborne virus or bacteria. As part of Wisconsin State Statute, 252 – Communicable Diseases, the NSHD is required to follow up and respond to all Category I and II diseases and conditions considered to have significant public health impact.

The Wisconsin Public Health Association is requesting funding be added to the State’s 2017-2019 Biennial Budget to support our communicable disease efforts. Wisconsin has no dedicated funding for Communicable Disease control and prevention, despite local health departments having 20 state mandates requiring disease surveillance, investigation, prevention and control.
