Bravo Pamela for the paper on prediction of cholera cases in Dhaka with the 2015-16 El Niño now in press in PloS One.  We learnt from the lack of an epidemic that local environmental conditions linking this global climate driver to disease spread are changing dramatically. This is an optimistic message for the future of cholera in the city, although it remains to be seen whether the low cholera levels persist if we enter a period of more frequent El Niño events.
