Infectious Disease Transmission

Infectious disease transmission occurs when pathogens, such as bacteria, viruses, or other microorganisms, move from one person or place to another. This can happen through direct contact (touching an infected person), indirect contact (touching contaminated surfaces), respiratory droplets (coughs or sneezes), or through vectors like insects. Factors like hygiene, vaccination, and immune response influence susceptibility. Understanding transmission helps in implementing measures like handwashing, wearing masks, and social distancing to prevent the spread and protect public health.
