Background Gambian sleeping sickness or HAT (human African trypanosomiasis) is a neglected tropical disease caused by Trypanosoma brucei gambiense transmitted riverine species of tsetse. A global programme aims to eliminate the as public health problem 2020 and stop transmission 2030. In South Chad, Mandoul area persistent focus where around 100 cases were still diagnosed treated annually until 2013. Pre-2014, control relied solely on case detection treatment, which lead gradual decrease in...
A citywide dog vaccination effort in Chad reduced the local spread of rabies from dogs to humans.
Rabies claims approximately 59,000 human lives annually and is a potential risk to 3.3 billion people in over 100 countries worldwide. Despite being fatal almost 100% of cases, rabies can be prevented by vaccinating dogs, the most common vector, timely administration post-exposure prophylaxis (PEP) exposed victims. For control prevention N'Djamena, capital city Chad, free mass vaccination campaign for dogs was organized 2012 2013. The campaigns were monitored parallel studies on incidence...
Background One root cause of the neglect rabies is lack adequate diagnostic tests in context low income countries. A rapid, performance friendly and cost method to detect virus (RABV) brain samples will contribute positively surveillance consequently accurate data reporting, which presently missing majority endemic Methodology/Principal findings We evaluated a rapid immunodiagnostic test (RIDT) comparison with standard fluorescent antibody (FAT) confirmed detection viral RNA by real time...
Transmission of rabies from animals to people continues despite availability good vaccines for both human and animal use. The only effective strategy achieve elimination dog the related exposure is immunize dogs at high coverage levels. We present analysis two consecutive parenteral mass vaccination campaigns conducted in N'Djamena 2012 2013 advocate feasibility effectiveness control through proof concept. overall reached by intervention was >70% years. Monthly reported cases decreased more...
Sleeping sickness, or Human African Trypanosomiasis (HAT), is caused by two distinct parasites. In East and Southern Africa, Trypanosoma brucei rhodesiense causes the Rhodesian form of disease (about 2% all reported cases [1]). Central West T. b. gambiense Gambian (G-HAT—about 98% The normally affects remote rural communities. people most at risk are those working outdoors for long periods, as they exposed to bite tsetse fly (Glossina spp.: Diptera), which transmits comparable diseases occur...
Close to 69,000 humans die of rabies each year, most them in Africa and Asia. Clinical can be prevented by post-exposure prophylaxis (PEP). However, PEP is commonly not available or affordable developing countries. Another strategy besides treating exposed the vaccination vector species. In countries, main domestic dog, that, once infected, a serious threat humans. After successful mass 70% dogs N'Djaména, we report here cost-estimate for national elimination campaign Chad. cross-sectional...
'One health' is particularly suited to serve mobile pastoralists. Dinka pastoralists in Sudan inspired Calvin Schwabe coin the term 'one medicine', indicating that there no difference paradigm between human and veterinary medicine. Our contemporary definition of any added value terms improved health humans animals or financial savings environmental services resulting from a closer cooperation animal sectors. Here we present summary studies with Africa which were done research partnership,...
In Chad, several species of tsetse flies (Genus: Glossina) transmit African animal trypanosomoses (AAT), which represents a major obstacle to cattle rearing, and sleeping sickness, impacts public health. After the failure past interventions eradicate tsetse, government Chad is now looking for other approaches that integrate cost-effective intervention techniques, can be applied by stake holders control tsetse-transmitted in sustainable manner. The present study thus attempted assess efficacy...
On the shores of Lake Chad, schistosomiasis among mobile pastoralists was investigated in a field laboratory. Point-of-care circulating cathodic antigen (POC-CCA) cassette test, reagent strip, and filtration were conducted on urine samples. Fresh stool samples subjected to Kato-Katz technique, fixed examined with an ether-concentration method at reference POC-CCA tests revealed Schistosoma mansoni prevalence 6.9%, compared only 0.5% by microscopy. Three pregnant women otherwise negative...
The seroprevalence of Rift Valley fever (RVF), brucellosis, and Q among domestic ruminants on the southeastern shore Lake Chad was studied. study area consisted two parts, including mainland islands. On mainland, conducted in nine randomly selected villages camps. islands, samples were collected from all four available sites. A total 985 serum 924 analyzed using enzyme-linked immunosorbent assay (ELISA) for RVF. 561 islands ELISA both Rose Bengal tests (RBT) brucellosis. apparent RVF by...
Summary Objectives To evaluate the public health impact of milk contamination in Bamako, Mali. Methods A case–control study assessed risk‐factors for food‐borne toxi‐infections with diarrhoea and vomiting as main clinical picture. total 131 schoolchildren between 5 20 years age were interviewed by trained interviewers schools Bamako. structured questionnaire was used to record problems, food particularly consumption habits socio‐economic indicators. Results Final multivariate logistic...
At Lake Chad in Central Africa, mobile pastoralists face economic losses due to livestock trematodiases. Fasciola gigantica and Schistosoma bovis—trematodes that affect livestock—share transmission ecology traits with haematobium S. mansoni cause human schistosomiasis. This project aimed at assessing treatment strategies elucidating the predictive potential of trematode infections. Schistosomiasis fascioliasis were investigated concurrently humans cattle by repeated cross-sectional surveys....
Introduction: la rage canine demeure une préoccupation en Afrique comme au Tchad. La présente étude vise à évaluer les Connaissances-Attitudes-Pratiques des populations pour prise charge appropriée personnes exposées et lutte efficace.
Dans le Sahel, entre la Mauritanie et Somalie incluant Nord Kenya, environ 20 à 30 millions de personnes vivent en transhumance. Le rythme leur migration suit l'évolution saisonnière du climat disponibilité des ressources, telle que l'eau, pâturage sel. Malgré une exposition élevée certaines maladies comme les zoonoses problèmes conditionnés liés au climat, pasteurs mobiles sont parmi populations quasiment exclues système santé, car mise disposition services sociaux adaptés un mode vie...
The primary methodology for this research involves conducting a series of fatigue tests on 50/70 bitumen to assess its behaviour under varying thermal conditions. will be carried out using Dynamic Shear Rheometer (DSR), widely used apparatus in testing. DSR allows measuring bitumen's rheological properties, such as viscosity and elasticity, controlled temperature stress samples carefully prepared according standard testing procedures ensure uniformity. heated specified testing, taken at...
Pastoral communities manage space and time in a way that enables them to take advantage of huge areas land which are largely desert not suitable for the development farming. Their approach, is based on mobility uses knowledge passed down by their ancestors, serves as both strategy managing risks optimising use seasonally available fodder resources. They harness economic potential have kept unique ecological system intact.
