Document Summary
Major foodborne pathogens in the us: norovirus. Number of hospitalization: salmonella, norovirus, campylobacter, cause bloody diarrhea and hus. Number of deaths: salmonella, listeria, norovirus, campylobacter. Foodborne disease surveillance in the us: center for disease control and prevention (cdc) Collaboration between cdc and 10 sites in us for a better understanding of the epidemiology of food-borne diseases: pulsenet: large nationwide data based that connects food-borne illness cases together and identifies outbreaks. Molecular subtyping network uses dna fingerprinting of foodborne bacterial pathogens to detect outbreaks bacterial pathogens to detect outbreaks: calicinet (2009): network to quickly identify norovirus outbreaks and linking them to a common source. Burden of foodborne illness in the us: in food net 1- surveillance areas 15% 122 deaths: only reports to cdc about the confirmed cases, cdc estimates per year. The burden of illness pyramid: whole genome sequencing wgs, look at all the words in a book vs all the chapters.
