Explore the latest in infectious diseases, covering pathogen outbreaks, transmission dynamics, and public health responses globally. Understand disease...
Infectious diseases are illnesses caused by pathogenic microorganisms such as bacteria, viruses, fungi, or parasites, which can be spread directly or indirectly from one person to another.
Transmission occurs through various routes, including direct contact (touching, coughing), indirect contact (contaminated surfaces), vector-borne (insects), food/waterborne, and airborne particles.
Key prevention methods include vaccination, practicing good hand hygiene, safe food preparation, avoiding close contact with sick individuals, and using protective measures like masks when appropriate.
An epidemic is a sudden increase in the number of disease cases beyond what is normally expected in a population. A pandemic is a global epidemic, affecting multiple countries or continents.
