HLTB16H3 Lecture Notes - Lecture 10: Antimicrobial Resistance, Poliomyelitis, Smallpox
Document Summary
Lec 10 public health in infectious disease, part 1. Incubation period: time from exposure of disease until symptoms show. Latent period: have disease but not showing symptoms. Communicability: you can transmit disease to other indvls, influences prognosis, how long it will take to recover, what treatments are needed. Six-link chain of infection: pathogens, definition: virus, bacterium or parasite that causes disease in humans. Ph approach: kill agent i. e. antibiotics problematic/faulty b/c of rise of antibiotic resistance. Ph approach: eliminate reservoir i. e. remove garbage: reservoir, definition: location which pathogen lives & reproduces, portal of exit, definition: route pathogen takes to leave infected host. Ph approach: knowledge important for understanding transmission & control measures: transmission, definition: method of travelling from reservoir/infected host to susceptible host. Ph approach: block point of entry i. e. wear long sleeves. Ph approach: block movement of pathogens i. e. quarantine infected individuals: portal of entry, definition: route pathogen enters host, susceptible host, definition: entry into host that isn"t immune.
