[Expert Solution]: PART I It is the early 1990s

PART I It is the early 1990s. The World Health Organization is planning a program for the global eradication of polio by the year 2000. Likura, a fictitious nation in south-central Africa, may become one of the countries selected to test the effectiveness of WHO’s polio eradication strategies. Unfortunately, little is known about polio in Likura. The Minister of Health therefore assigned the task of assessing the polio situation to a Princeton undergraduate who has recently completed GHP 351 and is doing a summer internship as the District Health Officer in Ababo. The Ababo District is a relatively poor, rural district with a single hospital and several health centers. The Ababo District has attempted to conduct surveillance on polio cases and deaths over the past five years. The hospital, health centers and all health workers are supposed to report such cases (based upon acute onset of flaccid paralysis and fever) to the District Health Officer. Question 1: What data might you use (or collect) to determine the incidence of polio in the population? What data might you use (or collect) to determine the prevalence of the sequelae of polio in the population? (Sequelae = a condition resulting from a disease. Here, lameness is the sequelae of polio that we are interested in.)
