Figure. The data for each month represent the number of episodes divided by the number of person-days in the month, multiplied
by 1000. The data for October 1991 began on 27 October. The onset dates for the participants' first diarrheal episode ranged
from 29 October 1991 to 15 May 1992 (median, 4.4 weeks after arrival). The earliest, median, and latest onset dates of all
307 diarrheal episodes were 29 October 1991, 15 July 1992, and 24 January 1994. The one person who was still in the study
from February through April 1994 did not have any diarrheal episodes during that period. Three of the four persons who had
only one or two episodes were in the study for only 5 to 10 months. Incidence of diarrheal episodes over time among Peace Corps volunteers in Guatemala.
