Q

divides the population into two equal parts. So, if the median age is said to be19 years old, it means half of the population belongs to 19 years and above, while the other half belongs to ages below 19 years old.

are considered economically dependent.
0 – 14 years old and 65 years old and above
25
are considered productive age group
15– 64 years old
26
it can be described in terms of urban-rural distribution, population density and crowding index.
Population distribution
27
simply illustrates the proportion of people living in urban compared to the rural areas.
Urban-Rural Distribution
28
describe the ease by which a communicable disease can be transmitted from one host to another susceptible host. This described by dividing the number of persons in a household with the number of rooms used by the family for sleeping.
Crowding index
29
determine how congested a place is. It can be computed by dividing the number of people living in a given land area.
Population density
30
Vital and Health Statistics/Indicators
General fertility Rate (GFR) Infant Mortality Rate (IMR) Maternal Mortality Rate (MMR) Crude Birth Rate The SWAROOP’S INDEX Morbidity rates
31
This rate is a more refined measure than crude birth rate because the denominator makes use of the number of women of a child-bearing age.
General Fertility Rate (GFR)
32
This rate is considered one of the most sensitive indices of the health conditions obtained in a population
Infant Mortality Rate
33
This rate measures the risk of dying from causes with childbirth.
Maternal Mortality Rate (MMR)
34
is only a rough measure of fertility in the population since it makes use of the mid-year population (which ignores the number of men and women incapable of child bearing) as its denominator.
Crude Birth Rate
35
is another proportional mortality indicator. It gives the percentage of all deaths, which occur in persons 50 years and above
The Swaroop's Index
36
implies the life expectancy is short and people die more of acute and communicable diseases.
Low index
37
refer to the number of people within a certain unit of the general population who have a certain disease or condition.
Morbidity Rates
38
Unit of population is generally (blank), although this may vary depending on location and the condition in question.
100,000
39
are used to help determine the overall prevalence of a specific illness.
Morbidity rates
40
Leading cause of Death in 2017
Ischemic Heart Disease Neoplasms Cerebrovascular diseases Pneumonia Diabetes mellitus Hypertensive Diseases Chronic Lower respiratory Infections Respiratory tuberculosis Other heart diseases Remainder of the disease of the Genitourinary system
41
Leading cause of Morbidity
Acute respiratory infection Acute lower respiratory tract infection and Pneumonia Bronchitis/Bronchiolitis Hypertension Acute watery diarrhea Influenza Urinary tract infection TB respiratory Injuries Disease of the Heart
42
Science concerned with the circumstances under which diseases occur, where diseases tend to flourish and where they do not.
Epidemiology
43
is the field of science, which is concerned with the various factors, and conditions that determine the occurrence and distribution of health, disease, defects, disability and death among groups of individuals.
Epidemiology
44
Is the study of the distribution and dynamics of disease occurrence in human populations as a basis for determining preventive and control measures.
Epidemiology
45
Uses of Epidemiology
 Determine whether epidemiologic data are consistent with etiological hypothesis  Provide basis for preventive and public health services.  Provide knowledge of disease frequency and distribution during epidemic and non-epidemic times
46
the constant presence of a disease or infectious agent within a given geographic area.
Endemic
47
the occurrence in a community or region of cases of a disease condition clearly in excess of normal expectancy and derived from a common or propagated source.
Epidemic
48
denoting a disease affecting or attacking all or a large portion of the population
Pandemic
49
denoting a disease affecting or attacking all or a large portion of the population
Sporadic
50
the entry and development of an infectious agent in the body of man or animal.
Infection
51
an organism, chiefly a microorganism but including helminths that is capable of producing infection or infectious disease.
Infectious agent
52
an apparent or manifest condition of man or animals resulting from an infection.
Infectious disease
53
the time interval between exposure to an infectious agent and the appearance of the first signs and symptoms
Incubation period
54
the person, animal, object or substance from which an infectious agent passes immediately to a host.
Source of infection
55
the first case that occurs to a family or community as a unit.
Primary case
56
a case resulting from a primary case.
Secondary case
57
any human being, animal, anthropoid, plant, soil, or inanimate object in which infectious agent normally lives and multiplies.
Reservoir
58
- a person or animal presumably not possessing sufficient resistance against a particular agent to prevent contracting a disease if or when exposed to the agent.
Susceptible
59
A person (or animal) who harbors a specific disease causing agent, in the absence of clinical manifestations and who served as a source of infection for others.
Carrier
60
A person (or animal) who has been in association with the infected person or animal or a contaminated environment.
Contact
61
frequency or occurrence of new cases of a disease in a population over a stated period of time expressed as a rate.
Incedence
62
limitation of movement of a person having a communicable disease or of a carrier who harbors an infectious agent.
Isolation
63
restriction of movement of those who have been in contact with a communicable disease for a period of time during which they maybe potentially infectious to others.
Quarantine
64
– an animal or plant in or upon which a parasite live. Any organism that harbors and provides nourishment for another organism.
Host
65
is the probability of a group or community developing an epidemic upon introduction of an infectious agent.
Herd Immunity
66
Epidemiologic Triad
Agent Pathogen, Host, Environment
67
determines the modes of transmission, natural history, occurrence, and control of disease, illness or other condition.
The interaction of host, agent and the environment
68
is an any, substance or force, either animate or inanimate, the presence or absence of which may serve as stimulus to initiate or perpetuate a disease process.
Agent of a disease
69
Agents
Biological, Chemical, Physical, Mechanical, Nutritive

72
Phases of Epidemiological Approach
Descriptive Epidemiology Analytical Epidemiology Intervention or experimental Epidemiology Evaluation Epidemiology
73
Concerned with disease distribution and frequency
Descriptive epidemiology
74
* Observation and recording of existing patterns of occurrence of the health condition under study * Description of the disease/condition as to person, place and time characteristics * Analysis of the general pattern of occurrence of the disease or condition.
Descriptive Epidemniology
75
Attempts to analyze the causes or determinants of disease through hypothesis testing
Analytical Epidemiology
76
answers questions about the effectiveness of new methods for controlling diseases for improving underlying condition
Intervention or experimental Epidemiology
77
attempts to measure the effectiveness of different health services and programs
Evaluation Epidemiology
