Preventive chemotherapy with praziquantel (PZQ) is the cornerstone of schistosomiasis control. However, a single dose of PZQ (40 mg/kg) does not cure all infections. Repeated doses of PZQ at short intervals might increase efficacy in terms of cure rate (CR) and intensity reduction rate (IRR). Here, ...we determined the efficacy of a single versus four repeated treatments with PZQ on Schistosoma mansoni infection in school-aged children from Côte d'Ivoire, using two different diagnostic tests.

To detect acute schistosomiasis, low-intensity infections, or to verify the success of treatment with
praziquantel, highly sensitive test methods are required. The aim of this study was therefore to demonstrate the
performance of Schistosoma mansoni spec...ific DNA detection in serum and urine using real-time polymerase chain
reaction (PCR) in an endemic area before and after treatment.

The results indicate a significantly higher rate of infections with S. mansoni in street children compared with orphans. This might be explained by the lack of access to adequate sanitation for street children ...as well as regular contact with the water of Lake Victoria. However, we did not find similar results concerning infection rates with protozoa. The study results show overall inadequate living conditions in this study population, which could be addressed by public health interventions.

Intestinal schistosomiasis is highly endemic in Tanzania and mass drug administration (MDA) using
praziquantel is the mainstay of the control program. However, the MDA program covers only school aged children
and does not include neither adult individuals nor... other public health measures. The Ijinga schistosomiasis project
examines the impact of an intensified treatment protocol with praziquantel MDA in combination with additional
public health interventions. It aims to investigate the feasibility of eliminating intestinal schistosomiasis in a highly
endemic African setting using an integrated community-based approach.

A manual for impact assessments. The SCH Practical and Precision Assessment (SPPA) strategy is an evidence-based approach for conducting impact assessments for SCH. The SPPA was identified by programme managers and SCH experts from the African region as a feasible and sufficiently accurate approach ...after reviewing and discussing the results of a multi-country study. This manual describes the resulting Practical and Precision Assessments approach and includes a discussion of the underlying concepts, factors to consider when determining what approach is appropriate, and how to interpret the collected data. The manual also includes annexes with standard operating procedures for conducting the stool and urine analyses.

Real-time polymerase chain reaction (PCR) is a sensitive and specific method for diagnosing schistoso-
miasis. However, this method should be performed in a laboratory, usually located distant from the sample collection
site. Therefore, it is important to have fas...t sampling preservation methods, which allow simple transport prior to DNA
extraction and amplification. The aim of this study was to verify if blood samples applied to filter paper are suitable for
analysis of Schistosoma mansoni DNA by real-time PCR.

Recently, schistosomiasis is reported also from Myanmar, viz. Rakhine State, Southern Shan State (near Lake Inle) and Bago Region. Between October 2016 and 30 June 2018, for instance, 302 cases have been diagnosed at Sittwe General Hospital.

Schistosomiasis is a public health problem in tropical and subtropical regions of Africa, Asia, the Caribbean and South America. It is one of the neglected tropical diseases (NTDs) - a group of diseases and conditions that affect particularly low-income populations, worldwide.
Last year, WHO laun...ched a new road map for 2021-2030 that aims to end the suffering from NTDs by 2030, in line with the Sustainable Development Goals. The road map specifically targets the elimination of schistosomiasis as a public health problem, globally.
This guideline provides evidence-based recommendations in the following areas: prevalence thresholds, target age groups and frequency of PC, establishment of WASH and snail control activities to support control and elimination of schistosomiasis, diagnostic tests for the assessment of schistosomiasis infection in animal reservoirs, in snail hosts, and in humans.
