The complexity of pathogens is influenced by several factors:
- Genetic variability: Pathogens like viruses can mutate rapidly, leading to new variants that may evade the immune system. - Host-pathogen interactions: The relationship between the pathogen and the host can influence disease severity and transmission dynamics. - Environmental factors: Climate, sanitation, and population density can affect the spread and survival of pathogens. - Antibiotic resistance: Overuse and misuse of antibiotics can lead to resistant strains, complicating treatment efforts.
