Colonization of a pathogen in such large numbers the host immune system is overwhelmed
Study of interactions between pathogen and host
Removal from a normal state of health
Process of changes to host’s body caused by pathogens, commonly called “symptoms”
A set of symptoms that occur together and characterize a disease or disorder
Causative agent of a disease
Describes a disease that is not transmissible
Describes a transmissible disease that spreads quickly to many people
Indicates severity and duration of a disease in a population, including current and past cases
Indicates spread of new cases of a disease in a population within a specified time period
Describes a disease that is stabilized and constantly present in a population
Describes a disease with intense symptoms, a short onset, and a short duration
Describes a disease in which the causative agent is initially inactive
Describes a disease with a long duration and mild symptoms
When many people within a community overcome an infection and gain immunity
A continual source of infection
Describes an infectious disease transmitted from animals to humans
Any nonliving object that can spread disease through contact transmission
An inanimate nonliving medium that can transmit disease
Extreme systemic immune response caused by infection and uncontrolled pathogen growth
