Abstract: This report summarizes the status of the global Dracunculiasis Eradication Program as of the end of 2021. Dracunculiasis (Guinea worm disease) has been eliminated from 17 of 21 countries where it was endemic in 1986, when an estimated 3.5 million cases occurred worldwide. Only Chad, Ethiopia, Mali, and South Sudan reported cases in humans in 2021.

This Is How We Finish off Guinea Worm
Op-ed by World Health Organization Director-General Dr. Tedros Adhanom Ghebreyesus and Carter Center Chair Board of Trustees Jason Carter in the Guardian/print edition special supplement
In the past 200 years, humankind has made incredible progress against many threats to health: vaccines, medicines and other innovations have saved millions of lives from feared killers, from malaria to cancer. But only one human disease – smallpox – has ever been eradicated. Less noticed by the rest of the world, we stand on the threshold of consigning another disease to the history books: Guinea worm.

Summary: Dracunculiasis (also known as Guinea worm disease), caused by the Dracunculus medinensis nematode, is progressing towards eradication, with a reduction in cases from 3·5 million cases in the mid-1980s to only 54 human cases at the end of 2019. Most cases now occur in Chad. On April 19, 2019, a 19-year-old woman presented with D medinensis in an area within the Salamat region of Chad, where the disease had not been previously reported. We aimed to investigate the connection between this case and others detected locally and elsewhere in Chad using a combination of epidemiological and genetic approaches.

Progress Toward Global Eradication of Dracunculiasis, January 2020–June 2021
Published by Centers for Disease Control and Prevention, Morbidity and Mortality Weekly Report / November 5, 2021 Vol. 70, No. 44; 1527–1533.
Authors: Donald R. Hopkins, MD; Adam J. Weiss, MPH; Sharon L. Roy, MD; Sarah Yerian, MPH; Vitaliano A. Cama, PhD
Abstract: With 27 cases in humans reported in 2020, five during January–June 2021, and only six countries currently affected by dracunculiasis (Angola, Chad, Ethiopia, Mali, South Sudan, and importations into Cameroon), achievement of eradication appears to be close. Existence of infected dogs, especially in Chad, and impeded access because of civil unrest and insecurity in Mali and South Sudan are now the greatest challenges to interrupting transmission.

Authors: Donald R. Hopkins, Kashef Ijaz, Adam Weiss, Sharon L. Roy, David A. Ross
In a recent article, Gebre suggests that endemic countries should lead in deciding on disease eradication initiatives and asserts that ‘elimination as a public health problem’ is the preferred option because eradication occurs at the expense of other health programs and weakens fragile health systems. The author's primary example is dracunculiasis (Guinea worm) eradication, but he fails to take into account that vertical disease elimination and eradication programs also strengthen health systems overall.

The Guinea Worm Eradication Program has been extraordinarily successful-in 2019, there were 53 human cases reported, down from the estimated 3.5 million in 1986. Yet the occurrence of guinea worm in dogs is a challenge to eradication efforts, and underlying questions about transmission dynamics remain.

Dracunculiasis, slated for global eradication, typically is acquired by drinking stagnant water containing microscopic crustaceans (copepods) infected with Dracunculus medinensis larvae, causing clusters of case persons with worms emerging from the skin. Following a 10-year absence of reported cases, 9-17 sporadic human cases with few epidemiologic links have been reported annually in Chad since 2010; dog infections have also been reported since 2012.

Guinea worm-Dracunculus medinensis-was historically one of the major parasites of humans and has been known since antiquity. Now, Guinea worm is on the brink of eradication, as efforts to interrupt transmission have reduced the annual burden of disease from millions of infections per year in the 1980s to only 54 human cases reported globally in 2019.

Dracunculiasis (Guinea worm disease) is caused by the parasite Dracunculus medinensis and is acquired by drinking water containing copepods (water fleas) infected with D. medinensis larvae. The worm typically emerges through the skin on a lower limb approximately 1 year after infection, resulting in pain and disability. There is no vaccine or medicine to treat the disease; eradication efforts rely on case containment to prevent water contamination.

Since 2012, an increase in GW infections in domestic dogs, cats and baboons has been reported. Because these infections have not followed classical GW epidemiological patterns resulting from water-borne transmission, it has been hypothesized that transmission occurs via a paratenic host. Thus, we investigated the potential of aquatic animals to serve as paratenic hosts for D. medinensis in Chad.

In the 1970s, a decade of peace opened up between civil wars in Sudan, allowing health workers to reach and immunize at-risk communities for smallpox. Without this window of peace, historians argue, smallpox might not have been conquered there. Recent outbreaks of violence (Dec. 15, 2013) in the new country of South Sudan have led some to speculate whether eradication efforts will succeed for another primeval plague — the Bible's "fiery serpent," known today as Guinea worm disease (dracunculiasis).

Disease Eradication
Published by New England Journal of Medicine, 2013; 368:54-63.
Author: Donald R. Hopkins.
Since the last case of naturally-occurring smallpox in 1977, there have been three major international conferences devoted to the concept of disease eradication. Several other diseases have been considered as potential candidates for eradication, but the World Health Organization (WHO) has targeted only two other diseases for global eradication after smallpox. In 1986, WHO's policy-making body, the World Health Assembly, adopted the elimination of dracunculiasis (Guinea worm disease) as a global goal, and it declared eradication of poliomyelitis a global goal in 1988. Although both diseases now appear to be close to eradication, the fact that neither goal has been achieved after more than two decades, and several years beyond the initial target dates for their eradication, underscores the daunting challenge of such efforts, as does the failure of previous attempts to eradicate malaria, hookworm, yaws and other diseases.

Coming on the heels the declaration of smallpox eradication in 1980 was the launch of the dracunculiasis (Guinea worm) eradication program, as a key outcome indicator of the success of the United Nations 1981-1990 International Drinking Water Supply and Sanitation Decade (IDWSSD). The dracunculiasis eradication campaign has carried on well beyond the close of the IDWSSD largely due to the efforts of President Jimmy Carter and The Carter Center, to assist the national Guinea Worm Eradication Programs in collaboration with partner organizations, including the Centers for Disease Control and Prevention (CDC), UNICEF, and the World Health Organization.

In 1986, the World Health Assembly (WHA) called for the elimination of dracunculiasis (Guinea worm disease), a parasitic infection in humans caused by Dracunculus medinensis (1). At the time, an estimated 3.5 million cases were occurring annually in 20 countries in Africa and Asia, and 120 million persons were at risk for the disease (1,2). Because of slow mobilization in countries with endemic disease, the 1991 WHA goal to eradicate dracunculiasis globally by 1995 was not achieved (3).

This report describes how Nigeria, a country that at one time had the highest number of cases of dracunculiasis (Guinea worm disease) in the world, reduced the number of cases from more than 653,000 in 1988 to zero in 2009, despite numerous challenges. Village-based volunteers formed the foundation of the program, which used health education, cloth filters, vector control, advocacy for safe water, voluntary isolation of patients, and monitored program interventions and cases reported monthly.

Dracunculiasis is a parasitic infection caused by Dracunculus medinensis. Persons become infected by drinking water from stagnant sources (e.g., ponds) contaminated by copepods (water fleas) that contain immature forms of the parasite. In 1986, the World Health Assembly (WHA) called for the eradication of dracunculiasis (Guinea worm disease) at a time when an estimated 3.5 million cases occurred annually in 20 countries in Africa and Asia and 120 million persons were at risk for the disease (1,2).

The World Health Assembly (WHA) first adopted a resolution calling for the eradication of dracunculiasis (Guinea worm disease) in 1986, when an estimated 3.5 million cases occurred annually in 20 countries (17 in Africa and three in Asia) and 120 million persons were at risk for the disease (1,2). Because of slow mobilization in countries with endemic disease, the global dracunculiasis eradication program did not meet the 1995 target date for eradicating dracunculiasis that was set by African ministers of health in 1988 and confirmed by WHA in 1991 (3).

This report summarizes the status of the global Dracunculiasis Eradication Program as of early 2008. By the end of 2007, dracunculiasis (Guinea worm disease) transmission had been eliminated from 15 of the 20 countries where the disease was endemic in 1986, only 9,585 cases were reported worldwide, and 2,016 villages still had indigenous cases of the disease. Two of the remaining affected countries (Nigeria and Niger) reported < 100 cases in 2007 and are on the verge of eliminating dracunculiasis if they have not stopped transmission already. Sudan, Ghana, and Mali are addressing their final challenges to interrupting all remaining transmission by the end of 2009.

The four diseases discussed in this chapter (dracunculiasis, onchocerciasis, schistosomiasis, and trachoma) are among the officially designated "Neglected Tropical Diseases," and each is also both the result of and a contributor to the poverty of many rural populations. To various degrees, they all have adverse effects on health, agricultural productivity, and education. The Carter Center decided to work on these health problems because of their adverse effect on the lives of poor people and the opportunity to help implement effective interventions.

The idea of a global campaign to eradicate dracunculiasis was first proposed by the Centers for Disease Control and Prevention in 1980, during the advent of the International Drinking Water Supply and Sanitation Decade (IDWSSD) (1981-1990). In 1981, the Steering Committee of the IDWSSD adopted eradication of dracunculiasis as a subgoal of their efforts to provide safe drinking water to unserved populations.

An analysis prepared by the Africa Human Development Department at the World Bank. By Aehyung Kim and Ajay Tandon, The World Bank, and Ernesto Ruiz-Tiben, The Carter Center. July 1997. ABSTRACT This paper is a cost-benefit analysis of the Global Dracunculiasis Eradication Campaign (GDEC). Dracunculiasis (or Guinea worm disease) has been endemic in several African countries as well as in Yemen, Pakistan, and India. In the past decade, the incidence of dracunculiasis has seen a remarkable decline as a result of GDEC. This paper compares expenditure on GDEC activities with estimates of increased agricultural production due to reductions in infection-related morbidity resulting from the eradication program. Using a project horizon of 1987-1998, the Economic Rate of Return (ERR) is 29%, under conservative assumptions regarding the average degree of incapacitation caused by
