“…To date, very few studies on tungiasis epidemiology in Africa have been published [3][4][5][6][7][8]. In 1981, Ejezie reported that 49.5% of primary schoolchildren in the Lagos State (Nigeria) were affected by tungiasis [4].…”

Introduction: Tungiasis is an infestation caused by the penetration in the skin of the gravid female of the flea Tunga penetrans (T. penetrans). The current epidemiological situation of tungiasis in Eastern Africa is poorly known. We present the results of a cross-sectional study on tungiasis which was carried out in Qameyu (Northern Tanzania). Methodology: Sixty-two schoolchildren with suspected cases of tungiasis were examined. Location, number, morphology and symptoms associated with T. penetrans infestation were recorded for each patient. Results: A total of 62 schoolchildren (38 males and 24 females), with ages ranging from 6 to 14 years, were examined. Sixty children were infested by T. penetrans. A total of 865 lesions were observed: 170 lesions were vital and 695 were non-vital. The first and the fifth toes were especially involved. The highest number of lesions observed in a single patient was more than 55 lesions. Pain was reported by 42 children, itching by 39 and difficult walking by 28. One child presented with fever which was considered to be caused by superinfected tungiasis. Complications were nail dystrophy (48 patients), deformity of the fingers or toes (12 patients), scarring (4 patients) and nail loss (4 patients). Thirteen children needed oral antibiotic therapy because of bacterial superinfections. Conclusions: Tungiasis is a public health concern in this region of Tanzania and it is associated with high morbidity. Improvement in housing hygiene, confining domestic animals and increasing the knowledge of the disease via health education are measures that should be taken to control the disease.

Tungiasis is a parasitic skin disease widespread in resource-poor urban and rural communities in Brazil. Inhabitants of an urban slum in Northeast Brazil were examined for the presence of tungiasis lesions and followedup twice a week for a period of three weeks. Each time the number, stages, and topographic localization of lesions were recorded on a documentation sheet. The infestation rate (number of newly embedded sand fleas per individual and day) remained stable during the observation period. The infestation rate was significantly related to the intensity of infestation (total number of lesions present) (rho = 0.70, p < 0.0001) and the proportion of viable lesions (rho = 0.28, p < 0. 0001). The results indicate that in an endemic area the infestation intensity and the proportion of viable lesions can be used as a proxy to assess the exposure of individuals at risk for tungiasis. Persistently high infestation rates during the transmission season favour the use of prevention measures against invading sand fleas (such as a repellent) rather than a drug to kill already embedded parasites.Key words: tungiasis -Tunga penetrans -epidemiology -morbidity -Brazil Tungiasis is a neglected parasitic skin disease of impoverished populations (Heukelbach et al. 2001). The ectoparasitosis occurs in Central and South America, the Caribbean and sub-Saharan Africa (Ade-Serrano & Ejezie 1981, Arene 1984, Matias 1989, Chadee 1994, 1998, Carvalho et al. 2003.

In the semi-arid Northeast Brazil, attack rates decrease as soon as the rainy season begins and re-increase when the weather becomes dryer. Environmental determined patterns in off-host propagation and development of T. penetrans seem to underlie the seasonal variation of attack rates.In contrast to other ectoparasitoses such as scabies and pediculocis, tungiasis is a self-limiting disease with duration of four to six weeks . As reinfestation is the rule and new lesions may appear close to already embedded fleas, cross-sectional surveys cannot be used to infer on local transmission dynamics. However, anecdotal observations from colonial times suggest that transmission dynamics vary considerably from location to location and that attack rates differ between individuals living in the same area (Karsten 1865, Jolly 1926, Gordon 1941.In fact, the number of embedded sand fleas per individual varies ...

“…Previous studies indicate that similar to other parasitic diseases, occurrence of severe tungiasis is linked to poverty [15,17]. This study shows that the poor communities of studied kebeles of Wolaita and Jimma were like that of Brazil, Trinidad and Nigeria, where there is high prevalence of tungiasis that is 16% to 54%) [18,19].…”
