Wellness and Disease Flashcards
is the active pursuit of activities, choices, and lifestyles that lead to a state of holistic
health- Global Wellness Institute
Wellness
is the act of practicing healthy habits on a daily basis to attain better physical and
mental health outcomes so that instead of just surviving, you’re thriving.- Pfizer
Wellness
failure of the body defense mechanism to cope with forces tending to disturb body
equilibrium.
Disease
Ecologic concept of disease based on 3 premises of the biologic laws
▪ Disease is a result of the imbalance between the forces of the agent and the host
▪ The resulting imbalance depends on the nature of the agent and the host
▪ The nature of the agent and the host and their interaction depend on the environment
Complete disease process starting from without or within the individual resulting in changes in body
form and function until equilibrium is reached, or recovery or death of the individual
Natural History of Disease
Natural History of Disease
- Portal of Entry
- Incubation Period
- Clinical Manifestation of Disease or Clinical Horizon
- Outcome of Disease
- Period of Communicability
Portal of Entry
Respiratory Tract
Genito-Urinary Tract
Gastro-Intestinal Tract
Skin
Blood Stream
Incubation Period
- Interval between the time of entry of the agent into the host and onset of signs and symptoms of disease, it varies from one
disease to another
Clinical Manifestation of disease or Clinical Horizon
Fever
Rash
Other symptoms like Jaundice
Nausea and Vomiting
Measurement of Physiologic data is abnormal
Positive laboratory tests of urine, blood, stools
Outcome of Disease
- a. Chronic condition
- b. Carrier state
- c. Temporary disability
- d. Permanent disability
- e. Death
- f. Complete recovery
Period of Communicability
The period during which the patient is infectious
is the organic body where the agent depends for survival
Host
influenced by sex, age, nutrition, heredity, and personality
development; habits and customs, race, previous experience
Resistance/Susceptibility
Human, Animal
Host
Climate, Housing, Healthcae settings, Travel
Environment
Viruses, bacteria, fungi, parasites
Agent
is the substance or force whose presence or absence causes disease
Agent
Types of Agent
Biologic
Physical
Chemical
Nutrient
Mechanical
Characteristics of Agents
Mode of transmission
Virulence
Organ of Parasitism
Immunity Conferred
a measure of the severity of the reaction
Virulence
Types of Disease Agents
Biologic Agent
Nutrient Agent
Chemical Agent
Physical Agent
Mechanical Agent
These living agents that parasitize man
Biologic agent
Examples are Arthropods, Helminths, Protozoa, Fungi, Bacteria, Rickettsiae, Viruses
Biologic Agent
Classified as carbohydrates, fats, proteins, vitamins, minerals, and water
Nutrient Agent
These agents maybe classified according to the mode of acquisition
Chemical Agent
This category comprises such factors as abnormalities at atmospheric pressure, temperature, and humidity in industry
Physical Agent
These agents are chronic friction and other mechanical forces that add unusual stresses to body mechanisms resulting in crushing, tearing, penetrating, wounds, sprains, dislocations, and or fractures
Mechanical agent
Different types of Disease Agents
Arthropods
Helminths
Protozoa
Fungi
Bacteria
Rickettsia
Viruses
Flies, lice, ticks, mites, fleas
Arthropods
Ascaris, schistosomes, hookworms
Helminths
Malaria, amoebae, leismania
ProtozoaA
Actinomycetes, monilia, histoplasma
Fungi
Cholera vibrio, streptococci, salmonella
Bacteria
R. prowaseki, R. quintana
Rickettsia
Influenze virus, psittacosis virus
Viruses
is the sum of all forces that influence the growth and development of an organism
Environment
Reservoirs of Infections are:
Man
Animal
Inaminate organic matter
Plant
Soil
Thing, person, object or substance from which an infectious agent passes
immediately to a host
Sources of Infections
This includes the geological structure of the area such as the hills, valleys, plateaus, soil, and
rock composition, and the presence of water, plants, etc.
Physical
The richer the area, the better the environmental sanitation, disposal of sewage and garbage,
availability of medical facilities, etc.
Socio-economic
This includes the “universe of living things that surround man, all else than man himself.”
