An unusual outbreak of hookworm disease in North India

An unusual outbreak of hookworm disease occurred after a game of "kabaddi" (a local game which results in much body contact with the ground) in 27 young males from one village. It was characterized by an immediate incapacitating dermatitis, followed by severe pulmonary symptoms. Progressive weakness, abdominal pain, weight loss and anemia developed within a few months. Ancylostoma duodenale was found in all except four patients who had received antihelminthic treatment. Specific treatment for hookworm resulted in complete clinical recovery. Features of the outbreak were: 1) the hitherto unrecorded mode of infection; 2) severe dermatitis; 3) pulmonary symptoms lasting more than 3 mo; 4) abdominal symptoms suggestive of subacute obstruction starting 4-6 mo after exposure; and 5) severe disability with weight loss for a period of 1 yr until specific treatment was administered.
