Table 1 Comparison of years with high (2010, 2014, 2015) and low dengue mortalities (2008, 2011, 2013) in Pune (2004–2015) based on dengue metric variables, wet weeks, flush count, count of active and break days of monsoon, and count of optimal temperature days. High dengue years in Pune (columns represented in red shade) exhibit lower cumulative rainfall, fewer rainfall flushes, and active-break days but a higher count of wet weeks compared to years with low dengue mortality (columns represented in blue shade). High dengue years have more days with optimal mean temperature (27–35 °C).
