TOPIC HAZARD QUESTION
Dietary Patterns and Food Supply All microbial hazards Among all subregions in 2010, what was the proportion of regional vegetable supply (tonnes) that was imported rather than produced domestically in the subregion with the highest such percentage?
Under-5 Mortality Rate Brucella spp., Echinococcus spp., intestinal protozoa, diarrheal pathogens Based on WHO’s estimates, think of the country in the African Region that had the largest percentage point decrease from 2000 to 2010 in all-cause under-5 mortality that was due to diarrhea. What was that percentage point decrease?
Disease Surveillance Enteric pathogens (developed subregions only) What will be the rate per 100,000 population of laboratory confirmed human cases of campylobacteriosis in 2012 in all EU member states as reported in EFSA’s annual report?
Systematic Review All microbial hazards Fewtrell et al. (2005) conducted a systematic review and meta-analysis to compare the evidence of relative effectiveness of improvements in drinking water, sanitation facilities, and hygiene practices in less developed countries in reducing diarrheal illness. The meta-analysis of 5 studies was used to estimate the relative risk of diarrheal illness with and without multiple interventions. What was the estimated relative risk?
