From: Epidemiological and molecular forensics of cholera recurrence in Haiti
Daily evolution of cholera in Haiti between November 2013 and November 2014: (Panel A) averaged daily accumulated rainfall in Haiti and derived dry season (see S2 Appendix for details); (Panel B) daily number of suspected cholera cases in the North, PaP (Port-au-Prince) and South zones as well as derived epidemic periods identified by the temporal cluster analysis; and (Panel C) daily number of stool samples for culture confirmation of cholera and monthly culture positivity ratio. Period P1 covers the late 2013 incidence peak and the abrupt decrease in cases during the 2013–2014 dry season; Period P2 covers a lull phase that extended through the end of the dry season (P2D) and the first months of the rainy season (P2R); Period P3 represents the intense epidemic recurrence that started in September 2014.
