Helminths

Some of the most overlooked diseases around the world are parasitic infections, especially those caused by a kind of parasite called helminths. The group includes hookworms and schistosomes, among others. These worms, which live inside their host, are especially common in developing countries. As we hear from health reporter Rose Hoban, a new study found that if you're infected with one, you're probably infected with others, too.

The study in Zanzibar, part of Tanzania, involved a three-drug regimen of ivermectin, albendazole and praziquantel. The drugs are active against worms that cause elephantiasis and schistosomiasis and soil-worms or helminths.
