Current status of Taenia solium and cysticercosis in Papua New Guinea.

There is no evidence that taeniasis due to Taenia solium is present in Papua New Guinea (PNG), but there is some serological evidence that human cysticercosis exists at particular locations near the border with West Papua (Indonesia), where refugees from across the border have been settled. Only a few surveys have been conducted; the first was in 1986, when one refugee who originated from an infected locality in West Papua was found to be serologically positive, but asymptomatic. Subsequently, there have been unpublished reports of more positive but asymptomatic cases amongst refugees and, it is claimed, amongst local inhabitants that live near the border. A serological survey conducted in PNG in 1999 at the southern end of the border revealed no positive cases of cysticercosis. There are no reports of pigs or dogs affected with cysticercosis in PNG.
