The heavy rain data prior to the BL outbreaks as per our mentioned that reports of mortalities from clinically diagnosed BL commenced1 week after the onset of heavy rains and following the onset of the monsoonal rainy season. That the rainfall in July 2017 considerably exceeded the mean rainfall data of the preceding decade, suggests there was correlation between the incidence of BL and an exceptional rainfall event (in bold).
