Recent systematic reviews and meta-analysis of the impact of chemical-based mollusciciding (King et al., 2015, Sokolow et al., 2016) have concluded that regular mollusciciding is likely to contribute significantly towards elimination of schistosomiasis in high-risk areas. The WHO roadmap’s new foc...us on “transmission control, wherever possible” (WHO, 2012a) reinforces the need to promote intermediate-host snail control to prevent schistosomiasis transmission.
This operational manual is intended to facilitate the reintroduction of practices and protocols for use of molluscicides in the field in schistosomiasis control programmes. It is complemented by guidelines on the laboratory and field testing of the efficacy of molluscicides for schistosomiasis control (WHO, 2017 [in preparation]).

DHS ANALYTICAL STUDIES 62
23 March 2021
The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

The World Health Organization (WHO) Global Status Report on Noncommunicable Diseases 2010 projects that noncommunicable diseases (NCDs) will be responsible for over 44 million deaths during the next decade, representing an increase of about 15% since 2010. Most of these deaths will occur in the WHO ...regions of Africa, South-East Asia and the Eastern Mediterranean. In the African Region alone, NCDs will cause around 3.9 million deaths by 2020.

The role of environmental contamination in transmission of COVID-19 virus is currently not clear. This protocol has been designed to determine (viable) virus presence and persistence on fomites in various locations where a patient infected with COVID-19 is currently receiving care or being isolated,... and to understand how this may relate to COVID-19 transmission events in these settings. It is therefore important that it is done as part of a comprehensive outbreak investigation and that information obtained by environmental studies is combined with the results of epidemiological, laboratory and sequence data from COVID-19 patient investigations.

The main purpose of the meeting was to review tsetse control tools, activities and their contribution to the elimination of gHAT and the monitoring thereof. Seven endemic countries provided reports on recent and ongoing vector control interventions at the national level (Angola, Cameroon, Côte d’...Ivoire, Chad, Democratic Republic of the Congo, Guinea and Uganda). Country reports focused on the in situations implementing and supporting vector control activities, the tools and the approaches in use, the coverage of the activities in space and time and their impacts on tsetse populations. Future perspectives for vector control in the respective countries were also discussed, including opportunities and challenges to sustainability.
