Communicable Disease

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.
