Dracunculiasis X in Vietnam –emerging public health threat or exotic gem?
In human parasitology, diseases with restricted geographical distribution, a life cycle remaining to be fully elucidated and a waxing-and-waning disease epidemiology are not the rule, but also not really exceptional, as illustrated by sarcocystosis in Southeast Asia (Esposito et al., 2014); or human lagochilascariasis minor in parts of central and South America (Barbosa Campos et al., 2017). Descriptions of geographically extremely limited clusters of a parasitic disease, far away from its known area of distribution, have been described; for example, gnathostomiasis spinigerum in Eastern sub-Saharan Africa (Raharisoa et al...

Lessons learned for surveillance strategies for trachoma elimination as a public health problem, from the evaluation of approaches utilised by Guinea worm and onchocerciasis programmes: A literature review
Conclusions/SignificanceThe experiences of both the Guinea worm and onchocerciasis surveillance strategies have very useful lessons for trachoma surveillance, pre- and post-validation. The use of a monetary reward for identification of TT cases and further exploration into the use of infection and serological indicators particularly in a post-validation setting to assist in identifying recrudescence would be of particular relevance. The next step would be a real-world evaluation of their relative applicability for trachoma surveillance. (Source: PLoS Neglected Tropical Diseases)

Investigation of Dracunculiasis Transmission among Humans, Chad, 2013-2017.
Abstract Dracunculiasis, slated for global eradication, typically is acquired by drinking stagnant water containing microscopic crustaceans (copepods) infected with Dracunculus medinensis larvae, causing clusters of case persons with worms emerging from the skin. Following a 10-year absence of reported cases, 9-17 sporadic human cases with few epidemiologic links have been reported annually in Chad since 2010; dog infections have also been reported since 2012. We conducted an investigation of human cases in Chad to identify risk factors. We conducted a case-control study using a standardized questionnaire ...
