The United Nations health agency says that a new global strategy targets a “raft of neglected tropical diseases” in the Caribbean and elsewhere.

The Geneva, Switzerland-based World Health Organization (WHO) said on Jan. 16 that dengue, leprosy, river blindness and guinea-worm disease are among 17 “neglected tropical diseases” now targeted by a new global strategy, supported by worldwide partners, “that provides a steady supply of quality medications.”

“With this new phase in the control of these diseases, we are moving ahead towards achieving universal health coverage with essential interventi­ons,” says Margaret Chan, WHO’s director-general, introducing a new report, entitled “Sustaining the Drive to Overcome the Global Impact of Neglected Tropical Diseases.”

The report shows new momentum in controlling, eliminating and eradicating some of the longest-term scourges faced by humankind that take their greatest toll among the poor, moving the world closer to the elimination of many of them.

“The challenge now is to strengthen capacity of national disease programs in endemic countries and streamline supply chains to get the drugs to the people who need them, when they need them,” Dr. Chan said.

According to the report, two diseases are targeted for global eradication, including dracunculiasis, or guinea-worm disease – which can produce a parasite as long as two or three feet – by 2015, and yaws, which attacks skin, bone and cartilage, by 2020.

Targets are set for the regional elimination of several other diseases in 2015 and in 2020, Chan said.

She said such targets can be set because of the donation of medicines and funding through an alignment of international partners, which helped bring about a “considerable scale-up of preventive chemotherapy and other actions through widespread delivery of single-dose, quality-assured medicines.”

In 2010 alone, Chan said 711 million people received treatment for at least one of four target diseases, including lymphatic filariasis, onchocerciasis, schistosomiasis and soil-transmitted helminthiases.

She said other targeted diseases include rabies, trachoma, buruli ulcer, chagas disease, human African trypanosomiasis, leishmaniases, taenaisis/­cysticerco­sis, echinococc­osis/hydat­idosis, foodborne trematodiases and lymphatic filariasis.

WHO projects that treatment for schistosomiasis alone will reach 235 million people over the next five years.

“The prospects for success have never been so strong,” Chan said. “Many millions of people are being freed from the misery and disability that have kept populations mired in poverty, generation after generation, for centuries.”
