- Association between climate variability and hospital visits for non-cholera diarrhoea in Bangladesh: effects and vulnerable groups

Table 1 Distribution of the weekly average of meteorological and river-level data in Dhaka, and the number of patients with non-cholera diarrhoea in ICDDR,B hospital, 1996–2002

Counts for Campylobacter, E. coli, Aeromonas and other diarrhoea are cases for 1996–2000.

Table 2 Percentage change in the number of non-cholera diarrhoea cases per week for 1°C increase in temperature at lag 0–4 weeks (1996–2002: ICDDR,B Dhaka Hospital)
