Document Summary

Chapter 14- infectious diseases, blood borne pathogens, and universal precautions. Infectious disease the invasion of a host (person or animal) by microorganisms called pathogens. Pathogens causes disease by disrupting vital body processes: most common pathogens = bacteria, viruses, parasites or fungi. Stimulate the immune system to react defensively: immune response = fever, inflammation, or other damaging symptoms. Microorganisms can live in host and be harmless until an agent & mode of transportation allows for transfer of microorganism, then pathogen, then infection. Contact of body surfaces: touching, sexual intercourse. Fecal-oral spread feces on hands, contact with mouth. Travels via inanimate object: water, food, towels, clothing, utensils. Airborne transmission: insects, birds, animals, infected particles suspended in air infected via sharing air supply. Through skin, respiratory system, digestive or reproductive system. Stages of pathogen infection: incubation, prodromal, acute, decline, recovery. After effectively managing invading antigens the system is primed for future encounter.
