Study Notes

Definition of Health and Disease

The World Health Organization (WHO) defines health as a state of complete physical, mental, and social well-being, not merely the absence of disease or infirmity.

Types of Agents

Biological agents that can initiate or perpetuate a disease process include bacteria, viruses, fungi, and parasites.
Hypercholesterolemia and abnormalities in metabolism are examples of metabolic agents.

Disease Transmission and Characteristics

Miliana Rubra (bungang araw, redness of skin fold, heat stroke) can be caused by prolonged exposure to high temperatures and humidity.
The nature of disease is a dynamic process involving the interaction of an infectious agent, a susceptible host, and an environment conducive to the spread of disease.
Physical agents that can lead to health problems include radiation, heat, and mechanical forces.

Transmission Mechanisms

The term for the mechanism in which an infectious agent is transported from the reservoir to a susceptible human host is transmission.
Direct transmission involves the unprotected host touching the patient, specimen, or a contaminated object (reservoir).
Indirect transmission involves a vehicle that passes an infectious agent immediately to the host, which may be a vehicle, vector, intermediate host, or contaminated article.

Characteristics of Infectious Agents

Virulence is a characteristic that directly relates to man and measures the severity of the reactions of an infectious agent, in terms of fatality.
Infectivity is a characteristic that measures the ability of an infectious agent to enter and colonize a host.
Pathogenicity is a characteristic that measures the ability of an infectious agent to cause disease in a host.
Immunogenicity is a characteristic that refers to the ability of an infectious agent to stimulate the host to produce a defense mechanism.

Radiation and Health Effects

Ionizing radiation can result in eye injury and skin damage, including accelerated aging.
Infrared radiation can cause thermal damage to the cornea, iris, or lens (cataract formation).

Mechanical Agents

Mechanical agents, such as chronic friction from vibrating tools (Jackhammer), can lead to vasospasms of fingers and carpal tunnel syndrome.

Reservoir and Vehicle

The term for the reservoir in which an infectious agent lives, multiplies, and depends primarily for survival is a natural reservoir.
A vehicle is an inanimate object, such as food, water, or air, that can pass an infectious agent to a susceptible host.
