I faced a serious ethical dilemma while attending a couple of cases of dengue fever at a ward in the Kolkata Municipal Corporation (KMC) area during September 2013. Two patients had tested positive for dengue IgM antibody by MAC ELISA. Adjacent to their house was a vacant plot of around 1500 sq feet and this was heaped with domestic waste from the neighbouring houses. The waste comprised plastic cups, thermocol plates, plastic bags and boxes of biscuits, cakes, chips and other foodstuff, coconut shells, bicycle tyres and earthen pots.
