Delhi's population explosion should not lead to epidemics and the result in human loss. The human resource of India's capital must be protected from diseases like malaria, dengue, diahorrea, etc.
Hygiene must be maintained in public places. Almost 50% of Delhi's population doesn't have sewers. This endangers the population, to a great extent. The public hospitals must be upgraded and made more efficient. Blood banks should never run out of stock. The personnel in the health services department must be made accountable for their lack of interest/action. In the 1990s, I had formed a Polio Sena, or volunteer army of children who took a vow to rid Delhi of polio. Something along those lines must be organized again.
