Several factors can influence the spread of infections:
- Pathogen Characteristics: These include virulence, infectious dose, and survival capabilities outside the host. - Host Factors: Age, gender, genetic predisposition, immune status, and behavior can all impact susceptibility to infections. - Environmental Conditions: Climate, population density, and socioeconomic conditions play significant roles in the transmission dynamics of infectious diseases. - Public Health Interventions: Measures such as vaccination, quarantine, and hygiene practices can significantly alter the course of an infection spread.
