Nematodes: worms of the world

Intestinal nematodes remain a world health issue. Their ubiquitous nature makes them difficult to control, and treatment is ineffective when the source of the infection can not be eradicated. International travel and immigration from developing countries have effectively increased the numbers of people infected in the US, especially in the northeast and southern coastal areas. It is important to provide sensitive and accurate methods to diagnose these parasites. Additionally, the WHO and other agencies must remain vigilant and continue their efforts to improve the health of vulnerable populations throughout the world.
