25
A type of cause that shows that it is a **complete pie**. The causal pathway to the development of a disease.
Sufficient Cause
26
What are some examples of **Sufficient Cause**?
- Skin contact with a strong acid - Burn
27
This is brought by specific infectious agent that can be **directly** or **indirectly transmitted**. **infectious** in nature. It develops quickly in individual with **a rapid onset and short duration of disease**.
Communicable Disease
28
How will **communicable diseases** transmit directly or indirectly?
- man to man - animal to man - animal to animal - environment to man
29
This **changes of pattern** of infectious diseases Discovery of new infections and the possibility that some chronic diseases have an infective origin.
Importance of Understanding Communicable Diseases
30
This **cannot be transmitted** towards another person. **Chronic** in nature and **slow onset and long duration of disease**.
Non-Communicable Disease
31
Sequence of events pertaining to the progression of a disease process in an individual over time. Absence of treatment.
Natural History of Disease
32
Stages of Natural History of Disease:
- Stage of susceptibility - Stage of Subclinical Disease (Pathologic Changes) - Stage of Clinical Disease - Stage of Recovery, Disability, or Death
33
This stage is where individual becomes more **prone to develop a disease** brought about by various factors due to a higher rate of exposure from the pathogen.
Stage of Susceptibility
34
In Stage of Susceptibility, this allow the body to respond accordingly to the presence of pathogen.
Exposure to pathogens
35
This stage influence in the physiologic activities of the individual’s body without him/her being aware of them during this time. **Pathologic changes** already develop **disease is asymptomatic during this stage**
Stage of Subclinical Disease
36
Type of **time of exposure** to onset of disease symptoms for **infectious diseases**.
Incubation Period
37
Type of **time of exposure** to onset of disease symptoms for **chronic diseases**.
Latency Period
38
This stage is where **most diagnoses are being made**. Validate the existence of an abnormality in the body.
Stage of Clinical Disease
39
Range as to the effect of disease process in an individual from mild to severe or fatal (recovery, disability or death)
Spectrum of Diseases
40
Proportion of **exposed persons** who become infected. Determining how many among the exposed should isolate or quarantine in order to **limit the exposure of a disease**.
Infectivity
41
Proportion of infected individuals who develop clinically apparent disease
Pathogenicity
42
Proportion of clinically apparent cases that are **severe or fatal**. The potential of a particular agent in terms of **counteracting the activity** of the body.
Virulence
43
This is the stage called **end result**. Whether he/she recuperates from the condition or will it worsen.
Stage of Recovery, Disability or Death
44
This is the result of **continuous interaction** of the elements and could lead to the **transmission of agent** from one susceptible host towards another.
Chain of Infection
45
What are the **6 components of Infection**?
- Infectious/Infecting agent - Reservoir - Route of exit - Mode of transmission - Route of entry - Susceptible Host
46
**Pathogen**. Microorganism that brings forth disease towards the host.
Infectious (Infecting) Agent
47
This is a **source** or “**habitat**”. Starting point for the **occurrence of a communicable disease**. Where the agent lives, grows, and/or multiplies.
Reservoir
48
There are how many Reservoirs?
3 (three): Human Reservoir, Animal Reservoir, & Environmental Reservoir.
49
This type of reservoir is the most common for infectious diseases Person-to-person and it can be a **case** or **carrier**.
Human Reservoir
50
A person identified as having the particular disease.
Case (Symptomatic)
51
Inapparent infection
Carrier (Asymptomatic)
52
This type reservoir has the humans as **incidental hosts**.
Animal Reservoir
53
This what you call an animal to animal transmission. Infectious transmissible under natural (vertebrate animals to humans).
Zoonosis
54
This type of reservoir has soil and other inanimate matter.
Environmental Reservoir
55
Pathogens **leaves** its host.
Route of Exit
56
This shows how an infectious agent can be spread from host to another.
Mode of Transmission
57
Direct transmission: Ex: - Skin-to-skin contact - Kissing - Sexual Intercourse are called:
Direct Contact
58
Direct transmission: Ex: - Sneezing - Coughing - Talking are called:
Droplet Spread
59
Indirect transmission: Ex: - Agent is carried by **dust** or **droplet** suspended in air. Called:
Airborne
60
Indirect transmission: Ex: - Agent include food, **water, biologic products, and fomites**. Called:
Vehicles
61
Indirect transmission: Ex: - Agent is carried through **mechanical means** Called:
Vectors
62
Pathogens **enters** a susceptible host.
Route of Entry
63
This is the **final link** where the individual **potentiates the development of disease**.
Susceptible Host
64
**Scattered about** and occurs **infrequently** and **irregularly**. Separated widely in time and place.
Sporadic Disease
65
This is a type of disease is constant presence and/or usual prevalence of a disease **within a geographic area**. **Usual** or expected frequency of disease
Endemic Disease
66
This is a type of disease is **persistent**, **high levels of disease occurrence**. A disease is constantly present at high incidence and/or prevalence rate and **affects all age groups equally**.
Hyperendemic Disease
67
This is a type of disease is **high level of infection** beginning early in life, affecting most of the **child population**.
Holoendemic Disease
68
This is a type of disease *increase*, **often sudden**, in the **number of cases of a disease** above what is normally expected in an area.
Epidemic Disease
69
Massively highly case confined in one area
Disease Outbreak
70
Aggression of cases grouped in place and time that are suspected to be greater than the number expected
Disease cluster
71
Epidemic that has spread over several countries or continents that affects a large portion of the population
Pandemic Disease
72
Imported into a country in which they do not otherwise occur
Exotic Disease
73
1. Recent increase in amount or virulence 2. Introduction of the agent into a setting 3. Enhanced mode of transmission 4. Change in the susceptibility of the host response to the agent 5. Increase host exposure or new portals of entry
Factors Affecting Increase of Cases
74
Promotion of healthy environmental conditions and prevention of environmental-related disease.
Environment, Health and Sanitation (EHS)
75
Study factors in man’s physical environment
Environmental Sanitation
76
1. Water quality surveillance 2. Evaluation of food establishments 3. Proper solid and liquid management 4. Sanitation of public places waste 5. Sanitation management of disaster areas 6. Assessment of environmentally critical projects 7. Enforcement of different sanitation laws, rules, regulations, standards
**Strategies** for environmental sanitation
77
**Major programs** for environmental sanitation:
1. Health and Sanitation 2. Water Supply Sanitation 3. Proper Excreta and Sewage Disposal Systems 4. Food Sanitation Program 5. Hospital Waste Management
