“…Podoconiosis has been reported in Equatorial Guinea [20], Cameroon, Chad, Niger and Nigeria, on the islands of Bioko, Sao Tome & Principe [21] and Cape Verde (Figure 1). This skin disease has also been reported in the Central American highlands in Mexico and Guatemala and South America, Ecuador, and Brazil [22, 23]. In India, filarial elephantiasis is the predominant form of disease, although there are also reports of podoconiosis in northwest India, Sri Lanka, and Indonesia.…”

Summary Podoconiosis or mossy foot is a form of non‐filarial lymphedema. This geo‐chemical elephantiasis is a disabling condition caused by the passage of microparticles of silica and aluminum silicates through the skin of people walking barefoot in areas with a high content of soil of volcanic origin. Podoconiosis is widespread in tropical Africa, Central America and North India, yet it remains a neglected and under‐researched condition. The disabling effects of podoco‐niosis cause great hardship to patients. It adversely affects the economic (reduced productivity and absenteeism), social (marriage, education, etc.) and psychological (social stigma) well‐being of those affected. Podoconiosis can be prevented; the main primary preventive measure is protective footwear. Secondary measures include a strict hygiene regimen and compression therapy, which can reverse initial lesions. Tertiary approaches include surgical management, such as shaving operations to reduce hyperplastic and verru‐cous elephantiasis.

“…Although the rates of poverty and environmental conditions are compatible with the existence of podoconiosis, unless information about the presence of the disease is backed by epidemiological surveys or surveillance data, a national or global response to podoconiosis cannot be initiated. This is particularly evident for countries reporting isolated cases, such as Brazil [ 47 ], where only one case was reported in the published literature. It is vital to gather more information on the current status of podoconiosis in countries such as Brazil.…”

Global epidemiology of podoconiosis: A systematic review

BackgroundPodoconiosis is one of the few diseases that could potentially be eliminated within one generation. Nonetheless, the global distribution of the disease remains largely unknown. The global atlas of podoconiosis was conceived to define the epidemiology and distribution of podoconiosis through dedicated surveys and assembling the available epidemiological data.MethodsWe have synthesized the published literature on the epidemiology of podoconiosis. Through systematic searches in SCOPUS and MEDLINE from inception to February 14, 2018, we identified observational and population-based studies reporting podoconiosis. To establish existence of podoconiosis, we used case reports and presence data. For a study to be included in the prevalence synthesis, it needed to be a population-based survey that involved all residents within a specific area. Studies that did not report original data were excluded. We undertook descriptive analyses of the extracted data. This study is registered with PROSPERO, number CRD42018084959.ResultsWe identified 3,260 records, of which 27 studies met the inclusion criteria. Podoconiosis was described to exist or be endemic in 32 countries, 18 from the African Region, 3 from Asia and 11 from Latin America. Overall, podoconiosis prevalence ranged from 0·10% to 8.08%, was highest in the African region, and was substantially higher in adults than in children and adolescents. The highest reported prevalence values were in Africa (8.08% in Cameroon, 7.45% in Ethiopia, 4.52% in Uganda, 3.87% in Kenya and 2.51% in Tanzania). In India, a single prevalence of 0.21% was recorded from Manipur, Mizoram and Rajasthan states. None of the Latin American countries reported prevalence data.ConclusionOur data suggest that podoconiosis is more widespread in the African Region than in the rest of the regions, although this could be related to the fact that most podoconiosis epidemiological research has been focused in the African continent. The assembled dataset confirms that comprehensive podoconiosis control strategies such as promotion of footwear and personal hygiene are urgently needed in endemic parts of Africa. Mapping, active surveillance and a systematic approach to the monitoring of disease burden must accompany the implementation of podoconiosis control activities.

“…In Latin America there are three countries (Brazil, Ecuador and Mexico) with moderate evidence for presence of podoconiosis. In Brazil, while Price reported two cases in São Paulo[2], another study in 1993 reported a case in Central Brazil[46]. Leon, in 1952 reported the presence of podoconiosis in Ecuador, in a subtropical region about 2000 m. above sea level[47].…”

“…In Latin America we identified only one case report from Brazil[46], making our evidence consensus framework highly dependent on Price’s monograph[2], the country’s surveillance capacity and the presence of confounding diseases. It will be critical to generate more data from moderate evidence and indeterminate countries in the region.…”

Mapping the global distribution of podoconiosis: Applying an evidence consensus approach

BackgroundPodoconiosis is a type of elephantiasis characterised by swelling of the lower legs. It is often confused with other causes of tropical lymphedema and its global distribution is uncertain. Here we synthesise the available information on the presence of podoconiosis to produce evidence consensus maps of its global geographical distribution.Methods and findingsWe systematically searched available data on podoconiosis in SCOPUS and MEDLINE from inception, updated to 10 May, 2019, and identified observational and population-based studies reporting podoconiosis. To establish existence of podoconiosis, we used the number of cases reported in studies and prevalence data with geographical locations. We then developed an index to assess evidence quality and reliability, assigning each country an evidence consensus score. Using these summary scores, we then developed a contemporary global map of national-level podoconiosis status.There is evidence of podoconiosis in 17 countries (12 in Africa, three in Latin America, and two in Asia) and consensus on presence in six countries (all in Africa). We have identified countries where surveillance is required to further define the presence or absence of podoconiosis. We have highlighted areas where evidence is currently insufficient or conflicting, and from which more evidence is needed.ConclusionThe global distribution of podoconiosis is not clearly known; the disease extent and limits provided here inform the best contemporary map of the distribution of podoconiosis globally from available data. These results help identify surveillance needs, direct future mapping activities, and inform prevention plans and burden estimation of podoconiosis.
