👉 The term "crowd infection" refers to the rapid spread of an infectious disease within a large group of people, often in close proximity. This can occur in settings like schools, workplaces, public transportation, or crowded gatherings where individuals are in regular contact. Factors such as poor hygiene, lack of social distancing, and high population density can accelerate transmission. When one person becomes infected, they can easily pass the pathogen to others through respiratory droplets, physical contact, or contaminated surfaces, leading to a swift outbreak. Effective public health measures, including vaccination, mask-wearing, hand hygiene, and social distancing, are crucial in preventing and controlling crowd infections to protect community health.
