With over 12,500 dengue cases in Delhi, a green NGO claimed that the ongoing fogging drive in the city was "not effective" in fighting thevector-borne disease, and has rather "harmful" effects on health, as the gas contains "95 per cent" of diesel in it. Saying that fogging only creates a "false" sense of security and is a way of "appeasing" people at the cost of their health, Centre for Science and Environment (CSE) urged the government to focus on systematic preventive measures towards clean environment and sanitation.
