Abstract


Sri Lanka experienced its largest dengue epidemic in 2017 with 110,372 reported cases and 301 deaths during the first seven months. Several factors including a change in the dengue virus serotype, unusually heavy monsoon rains and failure to control mosquito breeding sites may have contributed to the magnitude of this epidemic. We describe aspects relating to this large dengue epidemic and the control measures taken to combat it.
