Several factors contribute to the seasonal patterns of diseases. Some of the major reasons include:
Environmental Factors: Temperature, humidity, and precipitation can influence the survival and transmission of pathogens. Human Behavior: Activities such as travel, social gatherings, and occupational hazards vary with the seasons. Host Factors: Seasonal changes can affect the immune system and the nutritional status of individuals. Vector Ecology: The life cycles and population dynamics of vectors like mosquitoes and ticks are often seasonal.
