disease propagation

Disease propagation occurs when an infectious agent, like a virus or bacteria, spreads from one individual to others. This can happen through various ways, such as direct contact, respiratory droplets when coughing or sneezing, contaminated surfaces, or shared objects. Once someone is infected, they can unknowingly transmit the disease to others, leading to a chain reaction. Factors like close contact, high population density, and weakened immunity can accelerate spread. Preventing propagation involves measures like good hygiene, vaccination, wearing masks, and social distancing to interrupt transmission pathways.
