43
Q

3 Types of Reservoir

A

A.] Human carrier
B.] Animals
C.] Environment

44
Q

transmits the
infection before it becomes
symptomatic.

A

Incubatory carrier

45
Q

patients who had
recovered from an acute illness may
continue to shed the organism,
particularly enteric infections caused by
Salmonella or Shigella.

A

Convalescent carriers

46
Q

patients who
develop chronic infections and transmit
the infection for long periods of time,
usually over 1 year.

A

Chronic carriers

47
Q

diseases that can be
transmitted under natural conditions
from vertebrate animals to humans

A

zoonoses

48
Q

certain biologic agents,
such as cryptococcus neoformans, live
free in the environment.
1.] stagnant water esp. in canal where
mosquitoes can breed and multiply
2.] dirty surrounding
3.] unsafe water supply due to pipeline
leakage

A

Environment

49
Q

1.] respiratory tract
2.] genitourinary tract
3.] alimentary tract
4.] skin
5.] in user transmission – belongings
of an infected person like
handkerchief of a hepatitis infected

A

Portal of exit

50
Q

similar to the portal
of exit

A

Portal of entry

51
Q

occurs when the
reservoir and the susceptible host are in close
proximity.

A

Direct transmission

52
Q

occurs from skin
contact (i.e. syphilis) or w/ an organism in
the environment (i.e. sporotrichosis)

A

Person-to person spread

53
Q

occurs when infectious aerosols
produced by coughing, talking, and
sneezing transmit infection to susceptible
hosts. (i.e. mumps)

A

Droplet spread

54
Q

occurs when the
reservoir and the susceptible host
are separated. The separation can be
fast, near or in a far distance.
Examples:
1.] Vector spread involves mosquitoes,
fleas and ticks
2.] Vehicle spread involves transportation
of an infectious agent on
inanimate objects ( fomites ) like toys,
beddings or contaminated food, water,
milk or biologic materials.

A

Indirect transmission

55
Q

produced by
talking, singing, coughing, or
sneezing and float on air currents
for varying periods of time.

A

Airborne spread

56
Q

General Principles of Communicable Disease
Control

A

1.] Fixing of responsibility
2.] Authority
3.] Reporting
4.] Early diagnosis
5.] Isolation
6.] Immunization of contacts
7.] Quarantine
8.] Maritime quarantine or Ship quarantine
9.] Disinfection and fumigation
10.] Carrier control
11.] Community immunization
12.] Official’s responsibility for communicable disease
control
13.] Control of intermediate host

57
Q

The government is the one responsible for
the control of contagious diseases. The
practicing physician does not have direct
responsibility for enforcement of measures for
the control of communicable diseases.

A

The fixing of responsibility

58
Q

is required to control communicable
diseases. A police power is instituted to
protect the community from a recalcitrant
(disobedient) patient w/ a contagious disease
who refuses to observe the regulations of the
health department.

A

Authority

59
Q

A workable system for reporting all
contagious diseases in the community must
be devised. It is the duty of the practicing
physician to report all cases of communicable
diseases.

Reports should be made as soon as possible
after the tentative diagnosis has been made.

A

Reporting

60
Q

The physician who first sees the patient
makes a tentative diagnosis and institutes
tentative unofficial isolation measures.

He reports the case to the health
department

He may ask for any necessary laboratory
aids in diagnosis i.e. FTA-ABS test for
syphilis

A

Early diagnosis

61
Q

When the diagnosis of communicable
disease has been made the patient is
isolated
Purposes:
1.) isolation of the patient protects the
community from dissemination of the
specific agent to others.
2.) the patient is protected from factors
that may influence the course of the
disease unfavorably

A

Isolation

62
Q

After the patient has been isolated next to consider
is the possibility of preventing the disease among
his contacts. This is immunizing the family
contacts to get rid from such disease.

A

Immunization of contacts

63
Q

Family contacts and other immediate
contacts undergo quarantine. The
duration is from the date of last
exposure to the incubation period of
the disease.

The purpose is to prevent the spread of
the disease.

A

Quarantine

64
Q

Its purpose is to prevent the spread of a few highly
important communicable diseases from infected ports
to disease free nations.

This quarantine is organized on an international basis.

Diseases subject to quarantine such as cholera,
hepatitis A and B, yellow fever, typhus, plague, small
pox, leprosy, anthrax, AIDs, typhoid fever and CMV.

A

Maritime quarantine or Ship quarantine

65
Q

This is done by thorough cleaning, airing and sunning
of the sickroom, using only soap and water w/c are
adequate protective measures.

In the hospital all these matters are the responsibility
of the nurse who attends to the sick person.

A

Disinfection and fumigation

66
Q

The chronic carrier of an infectious agent is of great
importance as a source of infection in communicable
diseases.

The detection and control of carrier is the function of
the official health department

A

Carrier control

67
Q

There are cases that a mass community immunization
is needed to eradicate for the control of communicable
diseases.

The DOH takes charge of this project

To date the nation have a national immunization day to
give the population a chance to avail of free
vaccines and toxoids against some common infectious
diseases.

A

Community immunization

68
Q

The local health department is responsible for
communicable disease control measures.

This is usually aided by the national gov’t.

Often, the health department is aided by the
national laboratory services where the
production of biological products like
vaccine, toxoids and hyper-immune sera
takes place.

Then products are used for prophylactic and
therapeutic treatments.

A

Official’s responsibility for
communicable disease control

69
Q

Fumigation is now used chiefly to check
diseases that are transmitted by those insects
and rodents that are intermediate factors in
the spread of disease

The most effective fumigant is hydrocyanic
acid gas.

Steam is often used in the destruction of
infectious agents on clothing and is an
excellent germicide particularly if placed
under 15 lb pressure.
