“…A study conducted in Nigeria by Mafiana and colleagues [ 34 ] documented a prevalence of 71.8% (150/209) among PSAC infected with S. haematobium. Two of the included articles, which investigated both S. mansoni and S. haematobium in Senegal [ 27 ] and Ghana [ 24 ], did not report any cases of S. haematobium , while S. mansoni cases were documented in both studies.…”

“…In one article [ 22 ], the Kato-Katz test for S. mansoni was complemented by an ELISA test using soluble worm antigen, which did not distinguish between Schistosoma species [ 23 ]. The prevalence of S. mansoni in the included articles was estimated at 12.9% in Ghana [ 24 ], 3.6–80.3% in Kenya [ 22 , 25 ], 35.0% in Madagascar [ 26 ], 9.6–78.0% in Senegal [ 27 ], 11.2–35.4% in Sierra Leone [ 28 ], 44.4–54.9% in Tanzania [ 29 , 30 ], and 39.3–74.9% in Uganda [ 12 , 31 – 33 ].…”

Epidemiology of pediatric schistosomiasis in hard-to-reach areas and populations: a scoping review

Background Schistosomiasis affects over 250 million people worldwide. Despite children and the poor being key risk groups, limited research and control activities target pre-school aged children (PSAC) and hard-to-reach populations. As endemic countries shift the goals of their schistosomiasis programs from morbidity control to disease elimination, there is a need for inclusive planning to cover all affected age groups from all geographical areas and populations to achieve sustainable impact and health equity. Methods We conducted searches in MEDLINE, Web of Science, Embase (Ovid), and LILACS per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses—Extension for Scoping Reviews (PRISMA-ScR) guidelines. Quality assessment of identified articles was done using the Joanna Briggs Institute Prevalence Critical Appraisal Tool. Relevant study data were extracted from the articles and entered into Microsoft Excel 2016 for descriptive analysis. Results From the 17,179 screened articles, we identified 13 eligible studies on schistosomiasis in PSAC living in hard-to-reach areas and populations. All identified studies were from sub-Saharan Africa. The mean sample size of the retained studies was 572, with a balanced sex distribution among the young children sampled in each study. Ten studies investigated Schistosoma mansoni, one investigated Schistosoma haematobium, while two covered both S. mansoni and S. haematobium in the target population. The prevalence of S. mansoni among PSAC in the included studies was estimated at 12.9% in Ghana, 80.3–90.5% in Kenya, 35.0% in Madagascar, 9.6–78.0% in Senegal, 11.2–35.4% in Sierra Leone, 44.4–54.9% in Tanzania and 39.3–74.9% in Uganda. Out of the three studies that investigated S. haematobium, the presence of the infection was reported in only one study carried out in Nigeria. Schistosome infections reported in nearly all studies included in this review were of light intensity. Only one study conducted in Nigeria documented visible hematuria in 17.7% of the PSAC studied. Conclusions The findings document the high prevalence of schistosomiasis among PSAC in hard-to-reach populations and underscore the need to consider this population subgroup when designing the expansion of preventive chemotherapy and schistosomiasis control activities.

False-positive rapid diagnostic test for malaria in new world cutaneous leishmaniasis: a tale of two travelers

We report two immigrants from Cuba seen in a US travel clinic with a confirmed diagnosis of cutaneous leishmaniasis in whom we also suspected malaria co-infection. Both individuals likely acquired leishmaniasis in the Darien Gap region of Panama during their migratory path to the United States. As part of their clinical workup to rule out malaria, a rapid malaria antigen testing for P. falciparum was obtained and reported positive in both patients, However, both a qualitative reverse transcription-polymerase chain reaction (RT-PCR) for Plasmodium falciparum in blood and repeated thick-and-thin smear direct microscopy were negative in both, deeming the rapid malaria test as a false-positive. Thus, confirmation of malaria in travelers requires thick-and-thin film microscopy. Clinicians should be aware of the growing recognition of the possibility of false-positive malaria rapid diagnostic tests in those with some forms of leishmaniasis
