- Analysis a food poisoning outbreak case study (2010-2020) in any Arabian Gulf Country by focusing on: 1. Numbers of infected people. 2. Diagnosis. 3. Investigation. 4. Transparency. 5. Control. 6. Food poisoning causative recommendations.1. The leading cause of death worldwide is 2000 is due to 1) none 2) congenital disease 3) lifestyle risk factors 4) communicable disease 2. To differentiate incidence from prevalence: 1) whether the event is a new case ; time of onset of the disease 2) presence or absence of a disease ; time period is arbitrary ; rather a snapshot in time 3) number of new cases of disease during a specified period od time/population at risk 4) useful in the study of burden of chronic diseases and implications for health servicesRates of disease and death are elevated for historically marginalized racial groups, blacks (or African Americans), Native Americans (or American Indians and Alaska Natives), and Native Hawaiians and Other Pacific Islanders, who tend to have an earlier onset of illness, more aggressive progression of disease, and poorer survival.
