Q

occur in greater number than what is expected in a specific area over a specific time; outbreak

A

epidemic dz

22
Q

affects several countries or continents; global oubreak

A

pandemic

23
Q

those that are present in a population or community at times

A

endemic dz

24
Q

is any microbe capable of producing a disease; source of infection

A

causative agent

25
Q

are simple, one-celled microbes with double cell membranes that protect them from harm

A

bacteria

26
Q

is a bacterium with flexible, slender, undulating, spiral rods that possess cell wall

A

spirochete

27
Q

3 forms of spirochete

A

treponema
leptospira
borrelia

28
Q

smallest known microbes; they cannot replicate independently in the host’s cells.

A

viruses

29
Q

small, gram negative bacteria-like microbesa that can induce life threatening infections; transmitted through the bite of arthropod

A

rickettsia

30
Q

smaller than rickettsia but larger than a virus; cause of infection of the urethra, bladder, fallopian tubes, and prostate gland

A

chlamydiae

31
Q

are found almost everywhere on earth; beneficial in cheese, yogurt, beer, wine, certain drugs

A

fungi

32
Q

larger than bacteria; simplest single-celled organisms of the animal kingdom

A

protozoan

33
Q

absorb nutients from the body of the host

A

parasitic protozoa

34
Q

live at the expense of others and they dont usually kill their host but take only the nutients they need

A

parasites

35
Q

refers to the environment and objects on which on organism survives and multiplies

A

reservoir of infection

36
Q

carrier is a person who is incubating the illness

A

incubatory

37
Q

carrier is a person who is at the recovery stage of illness but continues to shed the pathogenic organism

A

convalescent

38
Q

carrier is a person who ocassionally sheds the pathogenic organism

A

intermittent

39
Q

carrier is a person who always has the infectious organism in his/her system

A

chronic or sustained

40
Q

is the path or way in which the organism leaves the reservoir; where the organism grows

A

portal of exit

41
Q

is the means by which the infectious agent passes through from the portal of exit of the reservoir to the susceptible host

A

mode of the transmission

42
Q

4 models by which the infectious agents can be transmitted

A

contact transmission
air borne tran.
vehicle tran.
vector tran.

43
Q

most common mode of transmission

A

contact transmission

44
Q

refers to a person to person transfer of organism

A

direct contact

45
Q

occurs when the susceptible person comes in contact with a contaminated object

A

indirect contact

46
Q

transmission through contact with respiratory secretions when the infected person coughs

A

droplet spread

47
Q

occur when fine microbial particles or dust particles containing microbes remain suspended in the air for a prolonged period

A

air bone transmission

48
Q

is the transmission of infectious disease through articles or substances

A

vehicle transmission

49
Q

occurs when intermediate carriers such as fleas, flies, and mosquitos tranfers microbes to another living organism

A

vector-borne transmission

50
Q

venue where the organism gains entrance into the susceptible host

A

portal of entry

51
Q

the human body has many defenses against the entry and multiplication of the organis; when the defenses are good, no infection will take place

A

susceptible host
