"Hookworm infection is widely prevalent in India. Necator americanus is predominant in south India, and Ancylostoms duodenal in north India. Recently, another species, A. ceylanicum has been reported from a village near Calcutta. The heavily infected areas are found in Assam (tea gardens), West Bengal, Bihar, Orissa, Andhra Pradesh, Tamil Nadu, Kerala and Maharashtra. More than 200 million people are estimated to be infected in India. It is believed that 60 to 80 per cent of the population of certain areas of West Bengal, UP, Bihar, Orissa, Punjab, and the eastern coast of Tamil Nadu and Andhra Pradesh are infected with hookworms."
