Sylvatic cycle
Sylvatic cycle
The Sylvatic cycle (pronunciation: sih-vat-ik cy-kul) is a term used in epidemiology to describe the natural lifecycle of certain pathogens in their reservoir species, often involving transmission to humans as incidental hosts.
Etymology
The term "sylvatic" is derived from the Latin word "sylvaticus", meaning "of the woods or wild", which is fitting as the sylvatic cycle often involves wild animals.
Definition
The Sylvatic cycle, also known as the wildlife cycle, is a part of the natural lifecycle of certain infectious diseases. These diseases are maintained in nature through biological transmission between vector species and reservoir species. Humans are not necessary for the maintenance of the pathogen in nature, but can become infected when they come into contact with the vectors or reservoirs, often through activities such as hunting, camping, or farming.

- Reservoir (epidemiology): The population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival.
- Epidemiology: The study and analysis of the distribution, patterns and determinants of health and disease conditions in defined populations.
