What are the Types of Time Patterns in Disease Occurrence?
Diseases can exhibit various temporal patterns, including:
Point source epidemic: A single, common source of infection leading to a rapid increase in cases over a short period. Continuous common source epidemic: Ongoing exposure to a common source, resulting in cases over a prolonged period. Propagated epidemic: Disease spread from person to person, leading to a gradual increase in cases. Seasonal trends: Fluctuations in disease occurrence corresponding to seasons, such as higher incidence of respiratory infections in winter.
