Ch 7 Flashcards
Prevention of the spread of contagious diseases through practices that contain and dispose of contaminated materials.
Sanitation
The government agency in the US that is responsible for protecting American’s health and medical safety.
Centers for disease control and prevention (CDC)
A viral inflammatory process and infection of the liver.
Hepatitis
The virus is responsible for AIDS.
Human immunodeficiency virus (HIV)
A disease of the immune system, which is caused by HIV.
Acquired immunodeficiency syndrome (AIDS)
Microorganisms that invade cells and insert their genetic code into the host’s genetic code. Viruses use the host’s cell’s nutrients and organelles to produce more virus particles.
Viruses
Primitive cells that have no nuclei. Cause disease by secreting toxic substances that damage human tissues, by becoming parasites inside human cells, or by forming colonies a in the body that disrupt normal function.
Bacteria
A group of simple parasitic organisms that are similar to plants but have no chlorophyll (green pigment). Most pathogenic fungi live on tissue on or near the skin or mucous membranes.
Fungi
One-called organisms that are larger than bacteria. They can infest human fluids and cause disease by parasitizing (living off) or directly destroying cells.
Protozoa
Large, multicellular organisms sometimes called metazoa. Most metazoa are worms that feed off human tissue or cause other disease processes.
Pathogenic animals
Contact with pathogens found in the environment in food, water, and soil, and on various surfaces.
Environmental contact
An infection caused by potentially pathogenic organisms that are found on the skin and mucous membranes of nearly everyone. These organisms do not cause disease until they have the opportunity, such as with impaired immunity.
Opportunistic invasion
The transmission of pathogens from one person to another through contact or often by airborne transmission.
Person-to-person contact
Procedures that kill or disable pathogens on surfaces to prevent transmission.
Aseptic technique
Procedures developed by the CDC is to prevent the spread of contagious diseases.
Standard precautions
