UK researchers have confirmed the emergence of intestinal schistosomiasis cases in Mangochi District, on the southern shores of Lake Malawi. The appearance of a new snail species in the area coincided with the detection of Schistosoma mansoni parasites among local schoolchildren, in some cases outnumbering cases of the endemic urogenital form (caused by S. haematobium).

Advice for travellers
Schistosomiasis or bilharzia is caused by a parasite which is released into fresh water by host snails. It burrows into the skin of people who swim or wade in rivers, streams and lakes containing the snail. With the rise in eco-tourism and adventure travel, increasing numbers of tourists are contracting schistosomiasis, according to a WHO fact sheet. Around 10% of travellers exposed to contaminated water will be infected. No vaccine or prevention medication is available, but schistosomiasis is treatable – especially if diagnosed early. Read more on the risk for travellers and how to prevent infection.
