Neglected Tropical Diseases and the Festival of Ideas

May 9th, 2012

Yesterday, the Global Network for Neglected Tropical Diseases, in partnership with the Embassy of South Africa, hosted a panel called “Integrated Approaches to Health and Development through NTD Control.”

The panel discussion was a part of larger event hosted by the Embassy of South Africa, called “Thought Leadership for the African Health Agenda.”  The Embassy is hosting similar events to spur ideas throughout 2012, as a part of their “2012 Festival of Ideas.”

The Global Network’s Managing Director, Dr. Neeraj Mistry, moderated the panel and hopes the discussion will improve awareness of and support for solutions to NTDs, diseases that have often been “hidden in the shadows.”

The panelists, Dr. Peter Hotez, President of the Sabin Vaccine Institute; Dr. Jennifer Kates, Vice President and Director of HIV Policy, Kaiser Family Foundation; and Dr. Ok Pannenborg, Former Chief Health Advisor, World Bank Group, shared their perspectives on NTDs, including the health impacts and existing treatments, the U.S. government’s approach, and the role of health systems. » Read more: Neglected Tropical Diseases and the Festival of Ideas

WASH and NTD Groups: Working together to achieve so much more

February 17th, 2012

By Kerry Gallo, Children Without Worms

Ned Breslin’s recent commentary in The Huffington Post regarding The London Declaration to control or eliminate 10 neglected tropical diseases (NTD or NTDs) brought up an important point: the NTD and WASH sectors need to leverage the many opportunities for collaboration that exist. Successful collaboration will be critical in making a big difference in controlling or eliminating NTDs.

Children Without Worms and Johnson & Johnson have been focused on soil-transmitted helminthes (STH), an NTD also referred to as intestinal worms. Nearly 600 million children around the world are at risk of STH, which leads to malnutrition, stunting and other irreversible damage which impedes long-term health and earning potential.

We have long understood that medicines are part of the solution — after all, drugs treat infection and once administered to an infected child, the benefits are almost immediate. But to keep children and families healthy for the long run, preventing infections from happening in the first place is vital. Access to clean water, sanitation and hygiene are key to making that happen and have therefore been central to our approach.

We have been proud and privileged to work through WASH partners in a few of our program countries, particularly Cambodia and Cameroon. In Cambodia, we have worked through the Ministries of Health and Education to conduct deworming days and to implement a curriculum our partner, Helen Keller International, developed to teach children the importance of hand washing and using sanitation facilities. In Cameroon, we work with the World Wildlife Fund, who builds latrines and provides access to drinking water in remote communities.

A recent literature review and meta-analysis on the impact of water and sanitation on STH control performed by the Swiss Tropical and Public Health Institute shows the benefits of this integrated approach. The study found that “the availability and use of sanitation facilities were associated with a reduction in the prevalence of infection with soil-transmitted helminthes [odds ratio of 0.51]”.

The London Declaration was indeed a moment in time for diseases that has affected so many people on our planet for too long. As we expand our program to other countries with increased donations of mebendazole from Johnson & Johnson and new donations of albendazole from GlaxoSmithKline, we will seek additional opportunities to partner with WASH-focused organizations whose expertise we welcome.  CWW also recognizes the importance of examining the effectiveness of combining various WASH interventions with treatment to combat STH infection, and plans to support research to strengthen the evidence base and inform the best strategies for comprehensive control.

I am reminded of a proverb used frequently in global health and development: If you want to go fast, go alone. If you want to go far, go together. This nugget of ancient wisdom remains true today. By working together to broaden an integrated approach to addressing NTDs, the WASH and NTD sector will be able to achieve so much more.

How the outhouse saved the South and what it can do for the world’s bottom billion

January 26th, 2012

Last century, the invention of the outhouse helped to eliminate hookworm and other parasites in the United States. Now new research shows that the lowly latrine could be a powerful tool in controlling these diseases, which remain widespread among the world’s poorest people.

It’s pretty simple. Whether people use it or just have access to it, the latrine could help save hundreds of millions of people from disabling disease. So concludes researchers from the Swiss Tropical and Public Health Institute, who found that in study sites, latrines halved the risk of infection from three common intestinal parasites- hookworm, roundworm and whipworm. Their research was published earlier this week in PLoS Medicine.

Hookworm, roundworm and whipworm- known collectively as the soil-transmitted helminthes or STH’s- are transferred from person to person through contact with feces-contaminated soil. It makes sense then that latrines or toilets would have a major impact on reducing transmission. This isn’t exactly a new idea. Today STH’s are most common in developing countries where there is limited access to clean water and basic sanitation. It wasn’t that long ago though that STH’s were a major problem here in the US, especially in the American South. It was the invention of the outhouse, in combination with anti-helminthes treatments, that helped eradicate these diseases. » Read more: How the outhouse saved the South and what it can do for the world’s bottom billion

Bugs, Animals and NTDs

June 13th, 2011

Animals and insects play a huge role in the transmission of neglected tropical diseases. From the snails that carry schistosomiasis to the wild animals infected with African sleeping sickness, the NTDs rarely travel alone. That means any effort to control and eliminate NTDs must take into account their many vectors and reservoirs of disease.

The NTDs are not zoonoses. That is, they are not diseases that animals can directly infect humans with. It’s more complicated than that. For example, in the case of human African trypanosomiasis, infected animals are bitten by the tsetse fly, which then carries the parasite to human victims. As long as animals remain infected, there is a risk of human infection.

In the case of schistosomiasis, the parasite that causes the disease has to spend part of its life living in certain kinds of snail. In this case, eradicating the snail would probably eliminate the disease, but doing it isn’t essential. They’re not a reservoir for the parasite, just a stopping point at one time in its revolting little life.[1] The animals reservoirs of schistosomiasis are dogs, cats, rodents, pigs, horses and goats[2], who just get infected with the disease the same way people do.

Be they roundworm, hookworm, nematode, or whipworm, the NTDs have got you totally covered for wormy horror.  In possibly the most yucky arrangement of all, many NTDs are causes by actual visible to the eye worms that LIVE INSIDE YOU. I hope my use of all caps conveyed my sheer horror to you. If it didn’t, go take a look at this picture of guinea worm removal, then come back here and try to pretend you aren’t horrified.
