Transmission: movement of a parasite from host to host. Incubation period: time required for the disease to development, replicate, etc. before any outward symptoms, the disease is doing something. Latent period: the disease is just not doing anything. It is just dormant, completely inactive period before (more) symptoms present themselves. Virulence: capacity of a parasite to cause a disease and inflict harm on the host (i. e. strength of the parasite) Zoonotic: infections that originate from animal sources and were somehow transmitted to humans. Plague = in the past, it referred to all disease outbreaks, to strike a blow that wounds . Now = highly infectious, usually fatal epidemic disease. The word plague also typically seems to refer to bubonic plague. Epidemiological triad: 3 main factors that influence the occurrence of a disease.
