TABLE C.3 Estimated Annual Number of Diarrheal Episodes for Various Regions (thousands)

TABLE C.4 Estimated Proportion of Diarrheal Episodes by Severity and Consequences, Assuming Current Levels of Intervention^a

	Age Group (years)
Category	Under 5	5–14	15–59	60 and Over
A (mild)	0.9	0.99	0.99	0.95
B (moderate)	0.08	0.008	0.008	0.04
C (severe)	0.02	0.002	0.002	0.01
H (death)	0.002	0.0004	0.0003	0.0005
^aThese values are estimated average proportions for all diarrheal etiologies. The number of episodes, which was ultimately derived by the methods presented here, reflects that for some pathogens severe cases are relatively more common than for all diarrheas aggregated (see Table C.9).
