NURS 3110 Lecture Notes - Lecture 4: Hypotension, Enterotoxin, Fomite
Document Summary
Describe the process of infection from point of contact to onset of disease. Understand factors the contribute to the virulence of a microbe. Identify components of normal host defense (mixed infection: two organisms that cause infection: contact: microbes adhere to exposed body surfaces, colonization with flora. Invasion: microbes cross lines of defense and enter sterile tissues. Immunocompromised: may not be able to amount response. Incubation period: cannot be classified in general, specific to organism you are considering (some organisms have 2 day incubation period, others have 30 days: organisms can lay dormant for many years without causing infection. Infectious stages: asymptomatic: have lots of infectious agent, more infectious, stages of release during infection: Incubation: convalescent, chronic, passive, transfer of infectious agent through contact, microbes can be passed from patient to provider and then from provider to another patient. Localized infection: did not go into main bloodstream: boil, systemic infection: septic, main bloodstream, true organism, opportunistic organism.
