The World Health Organization estimated Thursday that 1 billion of the world's poorest people suffer from neglected tropical diseases such as dengue, rabies and leprosy that remain concentrated in remote rural areas and urban slums despite being mostly eradicated from large areas of the world.
WHO said it can substantially reduce those numbers with the help of drug donations from the pharmeceutical industry, which announced fresh pledges.
WHO identified 17 diseases and disease groups present in 149 countries one-third of the 2.7 billion people living on less than $2 a day. Thirty countries have six or more of the diseases. In all, more than one-third of the 2.7 billion people living on less than $2 a day are affected.
"They cause massive but hidden and silent suffering, and frequently kill, but not in the numbers comparable to the deaths caused by HIV/AIDs, tuberculosis or malaria," said WHO director general Margaret Chan.
Still, Chan said that the diseases take a serious toll that serves to "anchor large populations in poverty."
Two of the diseases, onchocerciasis, known as river blindness, and trachoma, a bacterial eye infection, cause blindness. Leprosy and lymphatic filariasis, or elephantiasis, leave victims deformed, hamper productivity and normal social interaction, Chan said. Sleeping sickness, or human African trypanosomiasis, debilitates before it kills. Left untreated, rabies is fatal.
Novartis has renewed a commitment to donate drugs to treat leprosy, while GlaxoSmithKline said it would expand donations of a drug to treat worm infections and Sanofi-Aventis will continue its support to help eliminate sleeping sickness and other illness.
Also active in the fight are Bayer, Eisai and Johnson&Johnson, WHO said.
The stigma was especially hard on girls and women. "Many neglected tropical diseases cause disfigurement and disability, leading to stigma and social discrimination," diminishing marriage prospects and raising the likelihood of abandonment for women and girls, the report said.
Diseases like dengue don't garner the same sort of international response because the victims lack a political voice, and the diseases don't tend to spread to distant countries and only rarely affect travelers, the report said.
Among the strategies to control the neglected tropical diseases are expanding preventative chemotherapy, which means treating whole populations where such diseases are identified with drugs that may knock out several of the diseases at once.
The report also recommends doing a better job of identifying the diseases, improving sanitation and controlling insects and animals, which can spread the diseases into human populations.
Chan said the campaign is aimed at making a "deliberate effort" to eradicate the diseases as a means to alleviate poverty, rather than waiting for them to "gradually disappear as countries develop."
