Case Study 1: Parents bring their 2-year-old infant into the emergency room of a clinic. The infant is suffering with diarrhea and vomiting, and initial observation shows a dangerous level of dehydration. Initial tests do not indicate a bacterial infection or the presence of bacterial toxins. Discussion Ruling out the involvement of a bacterial pathogen, discuss what other pathogens may be involved (see Reoviridae and Caliciviridae). Discuss the characteristics of these viruses and their associated diseases.

Case study: Over 30 children younger than 3 years of age developed gastroenteritis after visiting a local water park. These cases represented 44% of the park visitors in this age group on the day in question. Older individuals were not affected. The causative agent was determined to be a member of the bacterial genus Shigella. The disease resulted from oral transmission to the children. Based only on the information given, can you classify this outbreak as an epidemic? Why or why not? If you were an epidemiologist, how would you go about determining which pools in the water park were contaminated?
