Lymphatic filariasis (LF) is a preventable neglected tropical disease (NTD) caused by infection with the filarial parasites Wuchereria bancrofti, Brugia malayi or B. timori. Mosquitos in the genera Culex, Anopheles, Mansonia and Aedes transmit the parasites from person to person. Lymphoedema and hyd

rocoele are the visible, chronic clinical consequences of the impairment of lymphatic vessels caused by infection with these parasites. WHO established the Global Programme to Eliminate Lymphatic Filariasis (GPELF) to stop transmission of infection by mass drug administration (MDA) of anthelminthics and to alleviate the suffering of people affected by the disease through morbidity management and disability prevention (MMDP). Since the start of GPELF, the number of infections has been reduced by 74% globally. The latest estimate is that 51.4 million people are infected.

Cotonou Declaration oBuruli Ulcer
Cotonou, Benin, 30 March 2009
Neglected tropical diseases kill, weaken or incapacitate millions of people every year, causing permanent physical suffering, social stigmatization and reduced productive capacity. Buruli ulcer, one such disease, causes immense suffer
...
ing and disabilities, especially among children. Delayed schooling and loss of productivity are considerable among the affected populations. These adverse consequences tend to aggravate poverty in affected communities. Globally, the disease has been reported in 30 countries. In WHO’s African Region, Buruli ulcer has been confirmed in 12 countries and is suspected in 10 others.
Significant progress has been made in the past 10 years in knowledge of Buruli
ulcer, investments in related research, control of the disease, and improvement
of tools for case diagnosis and development of treatment protocols. Substantial achievements have been made in diagnosis, treatment, immunology and epidemiology. Despite these achievements, little is known about the exact mode of transmission of the disease, and there is no simple diagnostic test usable in the field.
The use of antibiotics has revolutionized treatment and contributed to reducing the need for surgery by half. However, efforts are still needed to develop simple diagnostic tools usable in the field as well as disability prevention methods. The Global Buruli Ulcer Initiative has adopted the strategy recommended by WHO. The strategy is based on early diagnosis of the disease and the use of antibiotics for treatment upon the onset of the first signs by improving access to screening and case management at the most peripheral level of the health system.

Buruli ulcer is caused by Mycobacterium and belongs to the family of bacteria that causes tuberculosis and leprosy. Although the causative organism of Buruli ulcer is an environmental bacterium, the mode of transmission to humans remains unknown. The organism produces a unique toxin – mycolactone

hich the achievements of the Global Programme to Eliminate Lymphatic Filariasis (GPELF) would be confirmed. For the sake of harmonization, the terminology now used for elimination of lymphatic filariasis as a public health problem is “validation”. In 2015, the WHO Strategic and Technical Advisory Group for Neglected Tropical Diseases endorsed standardized processes for confirming and acknowledging success for all neglected tropical diseases targeted for eradication, elimination of transmission, or elimination as a public health problem.

Stop filariasis now
do the right thing to save the next generation
Lymphatic filariasis, commonly known as elephantiasis, is a neglected tropical disease. Infection
occurs when filarial parasites are transmitted to humans through mosquitoes. When a mosquito
with infective stage larvae bites a person, the parasites are deposited on the person’s skin from
where
...
they enter the body. The larvae then migrate to the lymphatic vessels where they develop
into adult worms in the human lymphatic system.

Progress towards achieving the Roadmap targets for control and elimination of the Neglected Tropical Diseases
Since 1996, trachoma has been targeted for elimination as a public health problem worldwide. The active trachoma criterion for national elimination as a public health problem is a TF1–9 < 5%, sustained for at least two years in the absence of antibiotic mass drug administration (MDA), in each formerly endemic EU. Using A, F and E, health ministries and their partners have made considerable progress towards achieving this criterion in formerly endemic EUs worldwide. In 2002, an estimated 1517 million people lived in EUs in which EU-wide implementation of the A, F and E components of SAFE were thought to be needed for the purposes of global elimination of trachoma as a public health problem; by June 2021, that number had fallen to 136.2 million, a 91% reduction. Approximately 85% of the 136.2 million people living in EUs needing A, F and E in June 2021 were in

Trachoma is the leading infectious cause of blindness (2). It is characterized by repeated

d indicators, including the 70 core indicators presented in the M&E framework. These indicators will also support reporting on strategies described in other road map companion documents to guide action against neglected tropical diseases include the sustainability framework, the global strategy on water, sanitation and hygiene, the One Health approach and the strategic framework for integrated control and elimination of skin-related neglected tropical diseases.
The purpose of this compendium is to guide monitoring and evaluation of programmes and thereby to improve their quality and effectiveness in alignment with the road map goals. It provides a standardized listing of the most widely used indicators relevant to countries, with uniformity in defining indicators to allow comparisons over time and among different programmes. Detailed metadata are provided for each of these indicators to facilitate validity, internal consistency, standardized measurement, estimation methods and comparability of data across countries.

In January 2021, the World Health Organization (WHO) published a new road map to address the burden of disease and death imposed by neglected tropical diseases (NTDs). The end of the first year of the 2021-2030 NTD road map is an opportunity to take
...
stock of where we stand and how we plan to move forward.
Considerable progress has been made since 2012 when the first road map was adopted. As of 6 June 2022, forty-six countries have eliminated at least one NTD, while 600 million people no longer require treatment because they are no longer exposed to risks associated with the pathogens that previously harmed them. In some cases, diseases that have plagued humanity for centuries, such as sleeping sickness and Guinea worm disease, are at an all-time low. Less tangible, but also important, there has been significant progress in the way NTDs are viewed. Additionally, the disruptive impact of the COVID-19 pandemic on NTD programmes is evident.
This brochure is the first in a series of advocacy briefs for the new NTD road map presenting highlights of success and challenges towards attaining the 2030 goals.

Following the death of the late esteemed Director Dr Mwelecele Ntuli Malecela earlier in the year, Dr Gautam Biswas had taken over as Acting Director but would soon retire; the appointment of a new Director was under way. Owing to rotation of STAG-NTD members, this would be the last meeting for some and the first meeting for several new participants. The work however would continue with the same commitment. Discussions over the next two days would focus on critical issues regarding recovery of NTD services following the disruptions caused by coronavirus disease (COVID-19), which had impacted many health services worldwide. He looked forward to receiving the advice and guidance of STAG-N
