Study Notes
Emerging Diseases and Public Health
- In the 21st century, emerging diseases have become a major threat due to high mobility and interdependent economies (Dr. Margaret Chan, Director General of the World Health Organization).
- Infectious agents could be used as an armament in wars, making bioterrorism a significant concern.
Role of Medical Technologists in Community and Public Health
- Medical technologists play a crucial role in primary level prevention, focusing on epidemiological efforts to determine causations of diseases.
- Developments like HDL level and serum aldosterone level have been made possible through clinical laboratory analysis, which is the work of medical technologists.
Three Broad Categories in Studying Community Health
- Primary Health Care: interventions focused on individual or family, such as hand-washing, immunization, circumcision, and use of condoms.
- Secondary Health Care: activities focused on the environment, such as draining puddles of water, cleaning bushes, and spraying insecticides to control vectors like mosquitoes.
- Tertiary Health Care: interventions that take place in hospital settings, such as intravenous rehydration and surgery.
Health Care Access Pyramid
- A model used in health care planning among government and non-government agencies worldwide, illustrating the position of health care services in the pyramid.
Population Distribution and Demographic Factors
- Population distribution refers to the general pattern of dispersion through the habitat.
- Demographic factors include age structure, sex ratio, and lifestyle, which are important to consider in profiling communities.
Nature of Growth
- Exponential growth: a doubling of the population in a specified time, occurring when circumstances of abundance for resources arise or when an important constraint has been removed.
- Biotic potential: the ability of a population to grow when resources are abundant.
- Limits to population growth include food, micronutrients, refuge from predators, living space, and pollution-free environment.
Epidemiologic Terms
- Endemic: an infectious disease habitually present in an environment.
- Epidemic: a occurrence of cases of an illness, specific health-related behavior, or other health-related events in excess of normal expectancy.
- Pandemic: an epidemic occurring worldwide or over a very wide area, crossing international boundaries, and usually affecting a large number of people.
Nature of Infectious and Non-Infectious Diseases
- Infectious diseases: diseases where a specific pathogen is associated with its occurrence, known as a causative agent.
- Non-infectious diseases: diseases in which no specific pathogen can be attributed to it.
- Communicable diseases: diseases that can be transmitted from one person to another.
- Contagious diseases: diseases that can easily be transmitted from one person to another.
Infectious Diseases
- Respiratory diseases: diseases of the respiratory system, including Upper Respiratory Tract (URT) and Lower Respiratory Tract (LRT) infections.
- Alvine discharge diseases: diseases related to the contents of the stools.
- Viral hepatitis: inflammation of the liver brought about by infection with any of the hepatitis viruses.
- Vector-borne diseases: diseases that require an intermediate, the vector, in the transfer of infectious agents from one person to another.
- Open lesion diseases: diseases where the skin is a portal of entry for disease-causing agents.
- Sexually transmitted diseases: diseases transmitted via sexual activities.
Biological Hazards
- Biological hazards: exponentially harmful microorganisms, including biologic (infectious agents), sharps, chemical, radioactive, electrical, fire/explosives, and physical hazards.
Chain of Infection
- Transmission of microorganisms requires a continuous link between the source, mode of transmission, and susceptible host.
- Breaking the chain of infection involves rapid and accurate diagnosis, environmental sanitation, handwashing, proper waste disposal, and immunization.
Prevention and Control
- Handwashing procedure: a 7-step process to prevent the spread of infection.
- Sharp hazard: disposing of sharp objects like needles and broken glasses in puncture-proof containers.
- Chemical hazard: handling chemical spills and using base solutions to neutralize chemicals.
- Fire hazard: types of fire and fire extinguishers, including ordinary combustibles, flammable liquids, electrical equipment, and cooking media.
Measuring Progress
- Control: ongoing operations or programs aimed to reduce the incidence and/or prevalence of a disease.
- Elimination: reducing the incidence of a disease to zero in a specific geographic area.
- Eradication: the permanent elimination of a disease worldwide, as defined by the World Health Organization.
