In fact, India fares far worse than China and is among the top 35 countries in the world with the highest death rate among under-5 children attributable to an unhealthy environment. While India recorded 248.14 deaths among children under-5 per lakh people annually, Myanmar (also part of the WHO's southeast Asia region) reported over 297, new assessments by the UN agency show.
Globally , more than 1 in 4 deaths of children under 5 years are attributable to unhealthy environments. Every year, environmental risks -such as indoor and outdoor air pollution, second-hand smoke, unsafe water, lack of sanitation, and inadequate hygiene - take the lives of 1.7 million children under 5, according to two new WHO reports. Highlighting the need for improved sanitation in India to save children, the WHO report said 44% of India's population defecate and urinate in open spaces, leading to greater risk of infectious diseases such as diarrhoea and acute respiratory infection along with malnutrition.
