HTH 100 Lecture Notes - Lecture 14: Mysophobia, Opportunistic Infection, Immunodeficiency
Document Summary
Endemic describing a disease that is always present to some degree. Epidemic disease outbreak that a ects many people in a community or region at the same time. Mysophobia (or germophobia) an obsessive dear or becoming infected with germs. Virulent strong enough to overcome host resistance and cause disease. Infection the state of pathogens being established in or on a host and causing disease. Epidemiological triad of disease the process explaining how a disease is likely to occur, including characteristics of the host (health of the immune system), the aged (pathogen and its virulence), and the environment (whether conditions are conductive to spread). First, the person, or host, must come into contact with a pathogen (infectious agent) able to overcome the body"s elaborate defense. Second, the host must be susceptible, or in some way vulnerable to infection. The pathogen must be virulent that it overcomes a healthy immune system, opportunistic infection, a normal pathogen overcomes an immunocompromised immune system.
