Infection

disease
Any change, other than an injury, that disrupts the normal functions of the body.
Host
the organism that a parasite or virus lives in or on
Incubation period
time between infection and appearance of first symptoms or signs of disease
Normal flora
Microorganisms that reside in or on the body without causing disease
Transient Flora
present for only a short period of time
Virulence
the degree or extent of pathogenicity of an organsim, may affect portal of entry and number of organisms.
Pathogen
An organism that causes disease
Opportunistic pathogens
Doesn't cause disease in healthy individuals, under certain conditions can cause disease. Exs: yeast infection - Candida albicans.
Microbial antagonism
When normal microbes benefit the host by preventing the overgrowth of harmful microbes.
Symbiosis
living together
Commensalism
symbiotic relationship in which one member of the association benefits and the other is neither helped nor harmed
Mutualism
a symbiotic relationship in which both species benefit
Parasitism
A relationship between two organisms of different species where one benefits and the other is harmed
Infectious disease
disease caused by a pathogen about 1/2 humans disease is this type.
Communicable disease
any disease that can be spread spread from one host to another directly or indirectly.
Noncommunicable disease
a disease that cannot be spread from person to person
Contagious disease
A disease that is easily spread from one host to another
Acute disease
develops rapidbly but lasts a short time (eg flu, RSF)
Chronic disease
A disease that developes slowly but the disease may be continual for a long time.
Subacute disease
Intermediate between acute and chronic
Latent disease
any disease in which a pathogen remains inactive for a long period of time before becoming active. EX. cold sore.
Endemic disease
Disease constantly present in a population
Pandemic disease
Worldwide Epidemic
Epidemic disease
when many people in a given area acquire a certain disease in a relatively short period of time
Local infection
an infection confined to a specific area of the body. Ex boils, pimples
Subclinical(Inapparent)

symptoms
changes in body that are not measurable. Ex. pain
signs
changes that can be observed and measured. Ex. Fever
syndrome
a group of symptoms or signs always accompany a disease. EX., TSS
Epidemiology
when and where diseases occur and how they are transmitted to in human population.
fomite
any object that harbors and transmitts pathogens. Ex. door knob
mutualism
a relationship between two species in which both species benefit
morbidity
incidence of a specific notifiable disease
mortality
Deaths from these diseases
