摘要: Analysis of a monthly 18-year cholera time series from Bangladesh shows that the temporal variability exhibits an interannual component at dominant frequency El Nino-Southern Oscillation (ENSO). Results nonlinear analysis support role for both ENSO and previous disease levels in dynamics cholera. Cholera patterns are linked to previously described changes atmospheric circulation south Asia and, consistent with these changes, regional temperature anomalies.
