The Infectious Disease Control Unit (IDCU) is responsible for assisting local or regional public health officials in investigating outbreaks of acute infectious disease or any report of isolated cases of rare or unusual disease, such as plague, cholera, or botulism. The program conducts routine and special morbidity surveillance of diseases designated by the Board of Health as reportable. The Unit is composed of two branches. The Emerging & Acute Infectious Disease Branch (EAIDB) and the Zoonosis Control Branch (ZCB).
