“…The prevalence of 58.7% found by the current study is much higher than the prevalence rate of 1.2% previously reported from a national survey in Ethiopia [ 10 ], 34.7% reported from Yirgacheffe district in southern Ethiopia and 1.6% reported from Brazil [ 14 ]. The reason for the difference could be that the current study was done in a dry season when the incidence is supposed to be at its peak.…”

BackgroundTungiasis is an ectoparasitic infestation, which still has public health importance in deprived populations of developing countries. Data on the prevalence and risk factors of tungiasis is rare in Ethiopia. Hence, this study was designed to determine the prevalence and risk factors of tungiasis among children in Wensho district, southern Ethiopia.MethodsFrom February to May 2016, we conducted a community-based cross-sectional study on 366 children 5–14 years old. Data about the presence and severity of tungiasis were obtained through inspection and data on risk factors were collected through interviews of parents/guardians of the children using structured questionnaire and through observation of the housing environment using structured checklist.ResultsTwo hundred fifteen (58.7%, 95% confidence interval [CI]: 53.7%, 63.8%) of the 366 children were infested with Tunga penetrans. Most lesions were localized in the feet and the distribution of the disease by sex was similar (57.4% among males and 60.3% among females). Children of illiterate mothers (adjusted odds ratio [AOR]: 3.62, 95% CI: 1.35, 9.73) and children whose mothers have attended only primary education (AOR: 2.72, 95% CI: 1.06, 6.97), children from cat owning households (AOR: 4.95, 95% CI: 1.19, 20.60) and children who occasionally use footwear (AOR: 7.42, 95% CI: 4.29, 12.83) and those who never use footwear (AOR: 12.55, 95% CI: 3.38, 46.58) had a significantly higher odds of tungiasis infestation.ConclusionTungiasis is an important public health problem with considerable morbidity among children in Wensho. Hence, implementation of tungiasis prevention strategies such as promoting shoes wearing, provision of health education, fumigating the residential houses and applying insecticides on pets are recommended.

“…Poor housing characteristics and the absence of a solid floor turned out to be independent risk factors for the presence of tungiasis and severe disease ( 76 ). Studies performed in rural Argentina and rural Venezuela, and in Santa Catarina State, Brazil described low economic status, presence of garbage on the compound, and lack of a solid floor as risk factors ( 55 , 61 , 62 , 64 , 70 ). However, these studies were not conceived as analytical studies and therefore do not allow a conclusion.…”

“…Human in people older than 60 years (13,56,57,59,60,62,68,70). Typically, women were less frequently infected than men, irrespective of age (57)(58)(59)(60)(61)(62)(63)(64)69). These findings suggest that children and the elderly are the most vulnerable population groups and bear the highest disease burden.…”

Objectives. To present the state-of-the-knowledge on the epidemiology of tungiasis in the Region of the Americas. Methods. A search of publications on the epidemiology of tungiasis in the Americas was performed in PubMed and LILACS databases from January 2007 to June 2021. In addition, a manual literature search on articles on the epidemiology of tungiasis was performed. Results. A total of 83 articles were analyzed which contained relevant information on tungiasis cases and their geographical distribution, prevalence and risk factors, life cycle, sites where transmission takes place, and zoonotic aspects. The on-host and off-host life cycles have been researched in detail. In certain contexts, the whole life cycle is completed indoors enabling transmission around the whole year. Cases were reported from 10 countries; 71% of them were from Brazil. In the general population, the prevalence varied between 1.0% and 82.6% according to the settings. Age-specific prevalence indicated that children and the elderly bear the highest disease burden. Risk factor studies indicate that tungiasis is associated with severe poverty. Conclusions. In the Americas, there are important gaps in information and knowledge of tungiasis. Understanding the burden, epidemiology, distribution, magnitude, related risk factors, and reservoirs, among others, is needed to develop and implement integrated control measures tailored to the context and patterns of transmission in the affected communities.

“…In Brazil, eight of the 13 species of Tunga occur (LINARD; AVELAR, 2014), which can be found from the extreme north (State of Roraima) to the extreme south (Rio Grande do Sul) (MUEHLEN et al, 2003), with prevalencerates, in the human species, between 16% and 55% (OLIVEIRA et al, 2014). Viestel and Silva (2012) affirm that, although it presents a high prevalence in this country, the parasitosis is, many times, unknown to the veterinarians of the great centers for being a zoonosis, who aresuch an important professional for the success in its eradication and control (VIESTEL; SILVA, 2012); and Damazio e Silva (2009), in turn, highlight that, despite its wide distribution, tungiasis is not considered a significant public health issue. Leles and Araújo (2015) suggest that, in the Amazon context, perhaps the most relevant ectoparasitism is caused by the T. penetrans flea, an age-old condition that is still considered a "plague" among indigenous communities in the Amazon.…”

Tungiasis is a neglected parasitic skin disease, caused by the female sand flea Tunga penetrans penetration, that is associated with poverty and occurs in many poor resourced communities in the Caribbean, South America and Africa. Although its effects on humans and domestic animals are well described in the literature, its epidemiology in indigenous populations remains enigmatic and little is known about the tungiasis impact on wild animals, such as jaguars, the only Panthera genus member on the American continent, an important species as an indicator of environmental integrity, which, in Brazil, is on the list of animals threatened with extinction by the Environment Ministry, categorized as vulnerable. The carnivore population decline in Amazon would be accelerated, especially in the eastern and southern border of the Amazonian domain, and it is known that anthropic factors favor the spread of generalist pathogens to new environments and species, representing a greater risk for wild populations. Thus, ectoparasites identification in jaguars is important not only to understand the role of this feline in maintaining the vectors in the wild, but also to know possible agents that can be transmitted by them. The objective of the present work is to report the tungiasis occurrence in five jaguars run over in Sinop, Sorriso and Lucas do Rio Verde, northern MT, between 2018 and 2020; this being the first scientific report found of parasitism by T. penetrans in jaguars in the Amazon biome. The lesions were found on the animals paws, characterizing phases two to five of the Fortaleza classification, and the infestations were evaluated as high, in the youngest animals, to low, suggesting that parasitism degree would be related to the age of the host.
