One hundred million people suffer from bilharziasis, or schistosomiasis. Several tens of thousands die from it each year. This disease, which thrives mainly in developing countries, could be treated – a laboratory in Rio de Janeiro has carried out the research and developed effective treatment, but neither the individual people nor the governments can afford it.
In Ireland and Australia, cattle are also infested with a form of the bilharzia blood fluke. The use of the vaccine has therefore now become profitable.
Lenna Pettersson, Miriam Tendler and Andrew Simpson look at the impact of this disease on public health and the economy
