Assessment of Epidemiological Implications Due to Serial Tropical Cyclones in India: Introspecting the Recent Sanitation Interventions

Abstract

The Indian subcontinent is prone to tropical cyclones that used to originate in the North Indian Ocean. Through this study, an inventory of disease outbreaks for the tropical cyclone-affected regions from 2010 to 2018 has been compiled. This inventory is used to assess the success of recent sanitation intervention, Swachh Bharat Mission, also known as the Clean India Mission. Meteorological parameters from the Indian satellites were used to demarcate the cyclone-affected area. Disease outbreaks and epidemics during the tropical cyclones were compiled from the Integrated Disease Surveillance Program and other relevant sources. The inventory has been used to track the effect of recent sanitation interventions on disease outbreaks. Districts in the eastern coast of India are frequently affected due to tropical cyclones that have originated from the North Indian Ocean. Infectious diseases like the acute diarrheal diseases, vector-borne diseases, viral fevers, enteric fevers, and food poisoning have recursively occurred during the cyclonic events and persisted up to 2 weeks from the cyclonic episode. The effectiveness of the Clean India Mission is evident during the recent cyclones, Ockhi, Titli, and Gaja, where a significantly lower number of infectious disease outbreaks were recorded. The Clean India Mission has exhibited positive results on the public health consequences associated with tropical cyclones.
