Reportable Diseases

Reportable Diseases montage

Communicable diseases are easily spread from person to person. Prompt reporting of a communicable disease can allow public health officials to locate and treat exposed persons, identify and contain outbreaks, and interrupt disease transmission. The information obtained from disease reporting is also used to monitor disease trends, identify high risk groups, develop policy, and design prevention programs.
