By law, certain diseases must be reported to local health departments according to Ohio Administrative Code (OAC) 3701-3-02 & 3701-3-03. Reportable diseases are of public health concern due to their severity, the potential for epidemic spread, and cause for public health concern. Diseases should be reported promptly to prevent secondary transmission.
Prompt notification of a communicable disease allows public health officials to:
Control and prevent the spread of communicable diseases
Determine the level of disease in the community.
Facilitate surveillance, prevention, and outbreak control.
