Communicable Diseases

What is a Communicable Disease?

A communicable disease, also called an infectious disease, is an illness that can spread from one person to another.1 Sometimes, these diseases can also be transmitted from animals or disease-causing microbes and pathogens.

The spread of disease can happen in various ways, including:

  • Breathing in viruses or bacteria in the air.
  • Contact with blood or other bodily fluids from someone who is sick.
  • Ingesting contaminated food or water.
  • Bites from insects or animals that can transmit the disease.

New York State (NYS) Communicable Disease Reporting

The NYS Sanitary Code (10NYCRR 2.10) mandates that suspected or confirmed communicable disease cases must be reported by certain health care providers and facilities that provide health care services.2 The state’s reporting requirements specify which diseases must be reported and when they should be reported.

Suffolk County Department of Health Services

The Bureau of Epidemiology and Disease Control within the Division of Public Health plays a central role in the Health Department’s mission to prevent the occurrence and spread of communicable disease.
