Health :
state of physical, mental and social well being and not merely the absence of disease
1 of 31
Pathology
The scientific study of disease
2 of 31
Developed world
Diseases related to lifestyle eg. increased food consumption, sedentary life style, smoking and alcohol
3 of 31
Developing world
Diseases related to poor living conditions eg. access to clean water, poor sanitation, poor infrastructure
4 of 31
Etiology
cause of disease
5 of 31
ENDOGENOUS
originating from inside the body eg. genetic defects
6 of 31
EXOGENOUS
originating from outside the body eg. microorganisms
7 of 31
MULTIFACTORIAL
many causes egdiabetes mellitus typ2
8 of 31
IATROGENIC
caused by the effect of a treatment eg. cytotoxic drugs for cancer
9 of 31
IDIOPATHIC
unknown cause eghypertension 90% unknown cause
10 of 31
PREDISPOSING FACTORS
conditions that may make an individual more susceptible to disease
11 of 31
Opportunistic infections
Predispose the individual to other conditions by allowing infectious agents, not normally pathogenic to cause disease
12 of 31
Morbidity
Effects of a disease on an individual
13 of 31
Mortality
Possibility of a disease causing death
14 of 31
ACUTE
Disease or clinical events that have a rapid, often severe onset but have a short duration
15 of 31
CHRONIC
Disease or clinical event that develops gradually over a long period of time and persists
16 of 31
Incubation period
period of time from exposure to manifestation of disease
17 of 31
Latent period
long period of time egcancers
18 of 31
Symptom
An indication that a disease is present and something the individual will complain about
19 of 31
Sign
Something a doctor will look for eg.
20 of 31
Subclinical stage
Signs and symptoms may not be apparent even though the disease is established and my require detection by laboratory
21 of 31
Syndrome
A disease that is characterised by multiple abnormalities that form a distinct clinical pattern
22 of 31
PROGNOSIS
the likely outcome of a disease
23 of 31
Remission
reduction or disappearance of the disease
24 of 31
Relapse
re-occurrence after a period of apparent
25 of 31
Communicable pathogens
transmitted from host to host and in general cannot live for extended periods outside the body
26 of 31
Non communicable pathogens
normally live in the abiotic environment but may infect a host if they are transmitted to a person/animal
27 of 31
Contagious pathogens
are easily transmitted. The sources of pathogens can be abiotic; soil water, animals or other humans
28 of 31
Host
An organisms that serves as nutrient source for a parasite
29 of 31
Parasite
An organisms that lives in/off an other organisms without providing any benefit to the host
30 of 31
Vector
An organisms that transmits a parasite via feeding off another organism
