World Mosquito Day

August 20th, 2010

By: Nathaniel Wolf, Sabin Vaccine Institute

August 20th is World Mosquito Day.  In 1897, Sir Ronald Ross looked at a mosquito under a microscope and saw that it looked really cool up close.  He declared August 20th World Mosquito Day and said we should be nice to mosquitoes, if only one day a year. 

Not really.  What Dr. Ross discovered was the link between mosquitoes and transmission of malaria.  He declared World Mosquito Day so that people would become educated about the life cycle of malaria, and in 1902 he won the Nobel Prize in Medicine for it.   In spite of this discovery, today the disease continues to be a threat to approximately 2.85 billion people, afflicting 250 million people around the world and causing an estimated 1 million deaths annually.

NTDs: Neglected Tropical Disasters

August 19th, 2010

By: Alanna Shaikh

More good news from me this week. New research shows that more kids in Africa are sleeping under bednets to protect them from mosquito-borne diseases like malaria and dengue. Here’s the big deal: in 1999, only 1.5% of children at risk slept under a net. By 2008 26.6% of children slept under a net. In Djibouti, Ethiopia, and Sao Tome, more than 80% of all children slept under a net. Considering that malaria caused 900,000 deaths in 2006, these kinds of advances really matter.

To make things even more interesting, the countries who did the best job of distributing bed nets and getting people to use them were also the countries that received the most aid for their malaria programs. That’s not exactly 100% proof that health aid works, but it comes awfully close.

Malaria has a lot in common with the NTDs. After all, it’s a tropical disease, too. It’s just not neglected. It shares territory, climate, and even modes of transmission with various NTDs. And, like malaria, we know how to prevent and cure NTDs. What worked for malaria – effective, targeted aid in quantities big enough to have an impact – will work for neglected tropical diseases, too. This research is a reminder and an inspiration. We really can defeat these diseases, bit by bit.

Are Certain Global Health Initiatives Disrupting Basic Medical Care In Poor Countries?

August 19th, 2010

It’s hard to argue against the fact that there are many global health interventions that can go a long way toward the control and elimination of  many neglected tropical diseases (NTDs). Global health initiatives have become an intrinsic part of international aid policy.

At a low financial cost, single disease campaigns  in various countries like Rwanda, Burundi, Mali and Sierra Leone for instance, have seen success in deworming children and treating patients for schistosomiasis, onchocerciasis, and trachoma.

Celebrating World Humanitarian Day

August 18th, 2010

Today we are celebrating World Humanitarian Day on End the Neglect! More than ever, the humanitarian community has been able to respond quickly to crises throughout the world, and provide relief in a timely fashion. Much of this success can be attributed to the selfless hard work and dedication from countless numbers of volunteers and aid workers. Today we recognize each and every one of these individuals and their tireless work.

In addition to this recognition, World Humanitarian Day is also a reminder that such tireless work is not nearly complete. The recent floods in Pakistan has affected millions of Pakistanis, causing displacement of individuals and an environment conducive to the spread of water-borne diseases. Aid remains to be unstable as food, clean water, and other relief supplies have been slow to reach victims. In the long-term, damages from the flooding pose to be a great threat to the country’s economy, and food and political security. It is at this point in time when humanitarian work is needed most.

In the world of NTDs, the high prevalence of schistosomiasis amongst African countries is a humanitarian crisis within the continent. As mentioned in a previous post, Africa is home to many who suffer from schistosomiasis, a disease affecting children, adolescents, and young adults. Symptoms include anemia, inflammation, and disability. Mass distribution of the drug Praziquantel is the only commercially available treatment for the disease, however, provision of the drug to Africa has been minimal. Authors Peter Hotez, Dirk Engels, Alan Fenwick and Lorenzo Savioli published an editorial in the August 13 edition of The Lancet calling for more Praziquantel, a drug that costs a few cents per pill, to reduce the schistosomiasis burden in a continent where individuals are most affected.

Observe World Humanitarian Day today! Visit the Global Network website and find out how you can help relieve the crisis of NTDs!

Ownership of Treatment Efforts for NTDs in Mali

As it takes a village to raise a child, it takes a community to control and eliminate NTDs. In Mali’s Segou Region resides Cinzana, a town made of 39 villages with 15,000 inhabitants with a high number of NTD cases. Diseases suffered by the area include trachoma, schistosomiasis, soil-transmitted helminthiasis, and lymphatic filariasis. Fortunately, Mali is one of 12 countries supported by an initiative funded by USAID called the NTD Control Program. Beginning in 2007, the Program partnered with the country’s Ministry of Health to distribute drugs and treatment to control NTDs. In Cinzana, distribution is conducted by a community group comprised of volunteers. Effective delivery of drugs to each infected individual can pose as a lofty endeavor. Limited resources and poor road infrastructures act as barriers to getting drugs to individuals in the outskirts of Cinzana, and becomes an even greater obstacle during the rainy seasons.

Despite these challenges, the NTD Control Program has been highly successful. By the end of 2009, the entire area of Cinzana received treatment. Much of this success is attributed to the community’s willingness to participate and be a part of the Program’s activities. Volunteers quickly recognized that effective distribution could only be reached if there was a large number of community drug distributors (CDDs). Thus, one of Cinzana’s economic interest groups, the Association of Community Health (ASACO), garnered the support of 200 much needed CDDs. In addition to the increase of CDDs, ASACO along with Mali’s government also provided more resources conducive to effective disease control such as notebooks, pens, and dosing poles, which are wooden tools used to identify the correct drug dosage for each individual.

Through community involvement and participation, Cinzana was able to reach 100% geographic coverage rates. Cinzana pledges to continue its diligence and dedication to the work of the NTD Control Program, working toward reaching goals and controlling NTDs.

To do your part in controlling and eliminating NTDs, please visit the Global Network website to get involved.

Support for NTD control in Mali is provided by USAID through a grant to Helen Keller International. Program activities are a part of the NTD Control Program led by RTI International. For more information, please visit http://ntd.rti.org/.

New Global Atlas will Transform Deworming Programmes

August 16th, 2010

As mentioned last Friday, the Global Atlas of Helminth Infections is a brand new tool that will track worm infections all throughout Africa. Below is the press release announcing its launch:

Partnership for Child Development

MAPPING THIS WORMY WORLD

New global atlas will transform deworming programmes

Maps showing the distribution and prevalence of worm infections in every African country will be launched today (17 August). These maps, called This Wormy World www.thiswormyworld.org, are the first of a series of Global Atlas of Helminth Infections which provide a unique, open-access, free information resource vital for planning and implementing deworming programmes.

It is estimated that more than 400 million children worldwide are infected with worms (helminths), 90 million in Africa alone. Worms damage children’s health, nutrition and educational achievement. Infections are most prevalent in poor communities where there is inadequate sanitation. The most common worm infections are soil-transmitted helminths (roundworm, whipworm and hookworm) and schistosomiasis.

This Wormy World identifies areas in a country that most urgently require mass treatment to control infection and predicts the risk of infection in areas where data is lacking. The Global Atlas of Helminth Infections has been produced by an international collaboration lead by the London School of Hygiene and Tropical Medicine and the Partnership for Child Development at Imperial College London. For a decade, the group has been gathering survey data to describe the distribution and prevalence of worm infection.

Announcing This Wormy World at the 12th International Congress of Parasitology in Melbourne, Australia, founder of the project, Dr Simon Brooker from the London School of Hygiene and Tropical Medicine, UK and KEMRI-Wellcome Trust Research Programme, Kenya, said, “Worm control is like a journey. The extent and location of the problem need to be mapped out in order to get treatment to where it is needed most. Until recently, much worm control has been a journey without reliable maps.”
