NEGLECTED TROPICAL DISEASES 2017-10-10T14:57:39+00:00

Neglected tropical diseases (NTDs) cause chronic suffering, disability, and equally crippling social stigma. After 20 years of work to control and eliminate these diseases, IMA World Health is celebrating a particularly exciting year of reaching new milestones and making history.

The Tanzania NTD Control Program (TZNTDCP) focuses on the five most common NTDs: lymphatic filariasis (LF), onchocerciasis, schistosomiasis, trachoma, and soil-transmitted helminthes. IMA supports mass drug administration (MDA) in 80 districts across 13 regions in Tanzania, distributing over 38 million treatments to over 15 million people annually and training more than 45,000 community drug distributors and distributing over 38 million treatments to over 15 million people annually. In 2016, IMA will work with the TZNTDCP to reach an additional 46 districts and 6 regions.

  • Participated in the largest national public health campaign to date in Tanzania, by joining a community NTD MDA with a Measles and Rubella vaccination campaign.
  • Together with the Task Force for Global Health and ENVISION, IMA and the TZNTDCP carried out LF remapping in 63 districts. Preliminary results indicate that LF MDA is not warranted in these 63 districts. Now that its LF map has “shrunk”, Tanzania is in a much better position to reach the 2020 LF elimination goals.
  • Carried out transmission assessment surveys (TAS) in 38 districts; preliminary results show disease transmission has been interrupted in most districts, which will no longer need treatment.

In October 2014, IMA World Health participated in one of the largest public health intervention efforts ever staged in Tanzania—a national joint immunization and mass drug administration (MDA) campaign to protect 21 million children against measles, rubella, and neglected tropical diseases (NTDs).

The 2014 national immunization campaign engaged thousands of vaccinators and volunteers, covering more than 12,000 schools and 6,600 health facilities over a one-week period—and making history in the effort to promote healthy communities in Tanzania.

USAID through RTI International | 2011 – 2019 | $9 million to date

IMA and partners conduct mass drug administration (MDA) to prevent and control the spread of lymphatic filariasis (LF) and soil transmitted helminthes (STH). IMA leads implementation in 9 of Haiti’s 10 Departments through community distribution posts
and schools with the help of 20,000 volunteers. IMA has trained these volunteers to educate their communities and distribute the
medication. The key goals: controlling the spread of STH, and eliminating lymphatic filariasis in Haiti by 2020.

  • Since 2008, IMA has administered over 28 million treatments, achieving 95% population coverage on average.
  • Carried out LF transmission assessment surveys (TAS) in 48 of Haiti’s 140 communes, with 46 of them passing TAS and able
    to stop treatment.

In 1999, the Haiti NTD Control Program set a goal to eliminate lymphatic filariasis (LF) from the population by 2020. With IMA support and funding from USAID, Haiti has made incredible strides toward reaching this goal, despite challenges that followed the massive 2010 earthquake. The first mass drug administration (MDA) was conducted in one commune in 2000. In 2012, the program reached national geographic coverage. By 2015, 48 of Haiti’s 140 communes were ready to undertake transmission assessment surveys (TAS) to determine whether infection rates were low enough to stop MDA. The surveys showed that 46 communes had met their elimination goals – a significant achievement for the country and a testament to the persistence of the program staff, partners, and volunteers. With additional TAS planned in 2016, IMA looks forward to further progress toward eliminating this debilitating disease.
