Bilharzia. Doctor palpating the abdomen of a man suffering from intestinal schistosomiasis (bilharzia). The disease is caused by blood flukes (in this case Schistosoma japonicum), which enter the body from infected water and travel to the blood vessels of the intestines. Symptoms include anaemia, liver cirrhosis, diarrhoea, dysentery and liver and spleen enlargement. The scar on his abdomen is from a splenectomy, an operation to remove his spleen, which was carried out because of a previous infection. Photographed at the Hunan Institute of Parasitic Diseases, China, in 1999.
