Infectious diseases large outbreaks

Farm animals being managed under intensive systems are very susceptible to disease outbreaks since they are usually of the same age, often very immature, and are in constant contact with their feces. Epidemiological studies have shown that the introduction of a highly infectious disease into a large population of animals kept in the same pen will ultimately result in a large proportion of these animals becoming infected (9). The reasonable therapeutic approach to this prob-... 

Populations affected by a disaster may experience severely diminished environmental conditions that put them at risk for negative health outcomes. Health promotion and disease prevention initiatives must be implemented immediately to protect the health of all affected individuals, including meeting basic physiologic needs in a timely manner to ensure survival. Infectious disease outbreaks will usually occur in the postimpact and recovery phases of a disaster (not during the acute phase), and the risks of epidemics increase if drought, famine, and/or large displacements of people are involved.
