| disease caused by an infectious agents such as bacteria, virus, protozoan or fungus | infectious disease |
| occurs when infectious agent enters body and begins to reproduce | infection |
| term for an infectious agent that causes disease | pathogen |
| organism infected by an infectious agent | host |
| the relative ability of an infectious agent to cause rapid and severe disease in a host is called | virulence |
| the degree of resistance a host has to a particular infectious agent | immunity |
| What fraction of deaths world wide are caused by infectious disease | 1/4 to 1/3 |
| what accounts for 1/2 of all deaths of children under 5 | infectious disease |
| what are the top killer infectious disease in the world | HIV/AIDS, TB, Malaria, |
| incubation period | time between infection and appearance of signs and symptoms |
| Prodromal phase | mild nonspecific symptoms signaling onset of disease |
| point of disease when host experiences typical signs and symptoms essentially feels like crap | clinical phase |
| Phase when signs and symptoms start to subside | decline phase |
| recovery phase | symptoms have disappeared and the patient begins to recover |
| Acute disease | develops and runs course quickly |
| Chronic disease | develops slowly and is usually less severe but can last for a long time |
| Latent disease | alternates between periods of infection and times with no disease apparent |
| infection contained to specific area of the body | local infection |
| generalized illness affecting most parts of the body | systemic |
| initial infection in a previously healthy individual | primary infection |
| infection that occurs in a person weakened by a primary infection | secondary infection |
| How do infectious agents cause disease | production of poisons (enzymes or toxins that destroy cells or tissues direct invasion and destruction of host cells triggering host immune system which leads to disease's signs and symptoms |
| Remember that personal characteristics provide chink in host's armor to allow disease | ok |
