INTECH - MARS 2012 - Au sommaire: The Re-Emergence of an Old Disease: Chikungunya Fever
Edited by Alfonso J. Rodriguez-Morales, ISBN 978-953-51-0274-8, 576 pages, Publisher: InTech, Chapters published March 16, 2012 under CC BY 3.0 licenseDOI: 10.5772/1335 Edited Volume Tropical Medicine has emerged and remained as an important discipline for the study of diseases endemic in the tropic, particularly those of infectious etiology. Emergence and reemergence of many tropical pathologies have recently aroused the interest of many fields of the study of tropical medicine, even including new infectious agents. Then evidence-based information in the field and regular updates are necessary. Current Topics in Tropical Medicine presents an updated information on multiple diseases and conditions of interest in the field.

INTECH - AVRIL 2012 - Zoonosis. Au sommaire: Insights into Leptospirosis, a Neglected Disease Edited by Jacob Lorenzo-Morales, ISBN 978-953-51-0479-7, 448 pages, Publisher: InTech, Chapters published April 04, 2012 under CC BY 3.0 licenseDOI: 10.5772/2125 Edited Volume Zoonotic diseases are mainly caused by bacterial, viral or parasitic agents although "unconventional agents" such as prions could also be involved in causing zoonotic diseases. Many of the zoonotic diseases are a public health concern but also affect the production of food of animal origin thus they could cause problems in international trade of animal-origin goods. A major factor contributing to the emergence of new zoonotic pathogens in human populations is increased contact between humans and animals. This book provides an insight on zoonosis and both authors and the editor hope that the work compiled in it would help to raise awareness and interest in this field.

Parasites & Vectors 2011, 4:232 (13 December 2011) Integrated prevalence mapping of schistosomiasis, soil-transmitted helminthia Treatment availability and capacity building Uganda's National Control Programme for combating intestinal schistosomiasis and STHs has been active since 2003, and although regular monitoring has occurred at intervals since then, this is the first comprehensive overview of the status of treatment infrastructure and health capacity on the districts adjacent to Lake Victoria. The results here paint a mixed picture; on the one hand, some villages appear to function well in terms of drug availability, regular training of CMDs and administration of mass treatment. However, there were also locations, such as much of Wakiso district islands, where people were sceptical about the efficacy or need to take PZQ, while in Masaka district there was a noticeable absence of volunteers willing to take on the role of CMD. The reasons given for refusal included the distance between sites and the lack of adequate funding for travel. High disease prevalence and observation of co-infection

PLOS 05/09/13 Lungworm Infections in German Dairy Cattle Herds — Seroprevalence and GIS-Supported Risk Factor Analysis In November 2008, a total of 19,910 bulk tank milk (BTM) samples were obtained from dairy farms from all over Germany, corresponding to about 20% of all German dairy herds, and analysed for antibodies against the bovine lungworm Dictyocaulus viviparus by use of the recombinant MSP-ELISA. A total number of 3,397 (17.1%; n = 19,910) BTM samples tested seropositive. The prevalences in individual German federal states varied between 0.0% and 31.2% positive herds. Annals of Clinical Microbiology and Antimicrobials 22/07/16 ChikDenMaZika Syndrome: the challenge of diagnosing arboviral infections in the midst of concurrent epidemics Arthropod-borne viruses are becoming and increasing threat worldwide, especially in the New World, which has recently witnessed an unprecedented outburst of Arboviral outbreaks [1, 2, 3, 4], such as the recent and ongoing chikungunya (CHIKV) [1] and Zika (ZIKV) [2] epidemics throughout the Pacific and the Americas. These emerging viral infections are largely due to a number of factors such as climate change [5, 6, 7], ever-increasing trends towards urbanization and growing travel and commercial exchange activities [8, 9, 10, 11, 12]; which have led to a spillover of these pathogens from their naturally occurring sylvatic niches and reservoirs into susceptible urban settings and newly unexposed geographic areas [13, 14, 15, 16]. Although 80 % of cases are asymptomatic, symptoms of ZIKV classically include mild or no fever, pruriginous maculopapular rash, conjunctivitis, arthralgia and myalgia, headache, malaise and fatigue (Table 1) [3, 25].

GRIDA - In the Grip of Malaria in Africa The GRID-Arendal Maps & Graphics Library is an on-going project to collect and catalogue all graphic products that have been prepared for publications and web-sites from the last 15 years in a wide range of themes related to environment and sustainable development. There are currently 3022 graphics available in the database. Urban growth rate in Africa Africa’s urban centres are currently growing at an annual rate that is the fastest compared to other regions. The urban expansion is expected to continue, with cities like Abuja and Ouagadougou expecting very high growth in the next decade, while Cairo, Africa’s largest city, is projected to see a comparatively lower growth rate.

PLOS 11/07/13 Strongyloides stercoralis: Global Distribution and Risk Factors Abstract Background The soil-transmitted threadworm, Strongyloides stercoralis, is one of the most neglected among the so-called neglected tropical diseases (NTDs). We reviewed studies of the last 20 years on S. stercoralis's global prevalence in general populations and risk groups. Methods/Principal Findings A literature search was performed in PubMed for articles published between January 1989 and October 2011. PLoS Negl Trop Dis. 2016 Apr 28;10(4):e0004677. The wMel Strain of Wolbachia Reduces Transmission of Chikungunya Virus in Aedes aegypti. Abstract Background New approaches to preventing chikungunya virus (CHIKV) are needed because current methods are limited to controlling mosquito populations, and they have not prevented the invasion of this virus into new locales, nor have they been sufficient to control the virus upon arrival. A promising candidate for arbovirus control and prevention relies on the introduction of the intracellular bacterium Wolbachia into Aedes aegypti mosquitoes. This primarily has been proposed as a tool to control dengue virus (DENV) transmission; however, evidence suggests Wolbachia infections confer protection for Ae. aegypti against CHIKV.

PARASITES AND VECTORS DEC 2009 Distribution, host preference and infection rates of malaria vectors in Mauritania In Mauritania, malaria is a major public health concern in southern and south-eastern regions. In fact, it is clearly on the increase and significantly contributes to the increase in illness and mortality, especially in children under 5 years of age and pregnant women [1]. In spite of this importance, little is known about its vectors.

BMC Research Notes 2013, 6:200 Strongyloides stercoralis is a cause of abdominal pain, diarrhea and urticaria in rural Cambodia Strongyloidiasis, an infection of an intestinal parasitic nematode, affects about 30–100 million people worldwide [1,2]. It is endemic in areas where sanitary conditions are poor and where the climate is warm and humid [3]. The clinical manifestations of strongyloidiasis vary greatly according to infection intensity and the immune-status of the patient. It is thought that more than 50% of all infections remain asymptomatic [4-6]. In Cambodia, a recent study showed that 24.4% and 49.3% of schoolchildren were infected with strongyloidiasis and hookworm, respectively [7]. Here, we report on the clinical manifestations of 21 strongyloidiasis patients from the rural province of Preah Vihear in northern Cambodia, with high numbers of S. stercoralis larvae in their feces.

Asian Pacific Journal of Tropical Medicine Volume 9, Issue 10, October 2016 Chikungunya infection: A potential re-emerging global threat Abstract Infectious diseases are indeed a lifelong threat to everyone irrespective of age, sex, lifestyle and socio-economic status. The infectious diseases have persisted among the prominent causes of death globally. Recently, re-emergence of Chikungunya viral infection harmed many in Asian and African countries. Chikungunya was considered as a major threat in developing and under-developed countries; the recent epidemiological outbreak of Chikungunya in La Reunion urges the global researchers to develop effective vaccine against this viral disease.

PLOS 09/05/13 A Public Health Response against Strongyloides stercoralis: Time to Look at Soil-Transmitted Helminthiasis in Full Strongyloides stercoralis infections have a worldwide distribution with a global burden in terms of prevalence and morbidity that is largely ignored. A public health response against soil-transmitted helminth (STH) infections should broaden the strategy to include S. stercoralis and overcome the epidemiological, diagnostic, and therapeutic challenges that this parasite poses in comparison to Ascaris lumbricoides, Trichuris trichiura, and hookworms. The relatively poor sensitivity of single stool evaluations, which is further lowered when quantitative techniques aimed at detecting eggs are used, also complicates morbidity evaluations and adequate drug efficacy measurements, since S. stercoralis is eliminated in stools in a larval stage. Specific stool techniques for the detection of larvae of S. stercoralis, like Baermann's and Koga's agar plate, despite superiority over direct techniques are still suboptimal. Figures
