Various factors can influence intermittent disease patterns:
1. Seasonal Changes: Weather conditions can affect the breeding of vectors like mosquitoes, which can in turn influence the incidence of diseases such as malaria and dengue fever. 2. Human Behavior: Travel patterns, holidays, and social gatherings can contribute to the spread of infectious diseases. 3. Environmental Factors: Changes in water supply, food availability, and sanitation can lead to intermittent outbreaks of diseases like cholera. 4. Immunity Levels: Population immunity can fluctuate, leading to periodic outbreaks when immunity levels wane.
