Communicable Diseases

Communicable diseases are illnesses caused by infectious agents like bacteria, viruses, fungi, or parasites that can spread from person to person, animal to person, or through contaminated objects and environments. Examples include the flu, COVID-19, and tuberculosis. These infections can vary in severity, from mild to life-threatening, and often spread through respiratory droplets, contact, or vectors. Preventive measures such as good hygiene, vaccination, and sanitation help reduce transmission. Understanding how these diseases spread is essential for controlling outbreaks and protecting public health.
