Recent epidemic activity and its introduction into the Western Hemisphere have drawn attention to West Nile virus (WNV) as an international public health problem. Of particular concern has been the ability for the virus to cause outbreaks of disease in highly populated urban centers. Incrimination of Australian mosquito species is an essential component in determining the receptivity of Austral...

Abstract The close relationship between water and poverty has been proven in several types of research. Water Poverty Index is an interdisciplinary approach for quantifying the socioeconomic aspects scarcity. enhanced (eWPI) aggregated five components: Resources, Access, Capacity, Use, Environment a Pressure-State-Response framework. In this research, eWPI computed on two scales: four community...

The outbreak of Ebola virus disease has caused unprecedented demands on health systems in west Africa, which were already fragile and are now at breaking point. The outbreak will be brought under control only with a massive input of money, infrastructure, and people.Crucial among the personnel needed are healthcare workers. For example,Médecins Sans Frontières (MSF), the most heavily involved c...

A serosurvey for mosquito-borne viruses was carried out in 93 wild boars (Sus scrofa), using a plaque-reduction neutralization microtest with Vero cells. The boars were sampled on 24 hunting grounds of the Breclav district (South Moravia) from 2000 to 2002. Specific antibodies to Flavivirus West Nile (WNV) were detected in six (6.5%) animals, and only in Lanzhot and Kostice, i.e., in the area o...

The emerging disease West Nile fever is caused by West Nile virus (WNV), one of the most widespread arboviruses. This study represents the first test of the vectorial competence of European Culex pipiens Linnaeus 1758 and Stegomyia albopicta (= Aedes albopictus) (both: Diptera: Culicidae) populations for lineage 1 and 2 WNV isolated in Europe. Culex pipiens and S. albopicta populations were sus...

West Nile Virus (WNV) is a globally important mosquito borne virus, with significant implications for human and animal health. The emergence and spread of new lineages, and increased pathogenicity, is the cause of escalating public health concern. Pinpointing the environmental conditions that favour WNV circulation and transmission to humans is challenging, due both to the complexity of its bio...

We use recent data on transport costs in West Africa, including the added burden of bribes and enforced delays, to show how such costs represent a deterrent to investment in — and therefore the sustainability of — agricultural assets. We focus on data for two important tree crops in West Africa, cashew and shea. We also have data for the transport of onions between Niger and the urban market in...

With the rapid global spread of West Nile virus (WNV) and the endemic state it has acquired in new geographical areas, we hereby bring a thorough serological investigation of WNV in horses in a longstanding endemic region, such as Israel. This study evaluates the environmental and demographic risk factors for WNV infection in horses and suggests possible factors associated with the transition f...

BACKGROUND Phylogenetically distinct Mycobacterium tuberculosis lineages differ in their phenotypes and pathogenicity. Consequently, understanding mycobacterial population structures phylogeographically is essential for design, interpretation and generalizability of clinical trials. Comprehensive efforts are lacking to date to establish the West African mycobacterial population structure on a s...

Analysis of the genome of the flavivirus responsible for the 1999 New York City encephalitis epidemic cloned from human brain by reverse-transcription polymerase chain reaction Indicates its identity as a lineage I West Nile virus (WNV; WNV-NY1999) closely related to WNVs previously isolated In the Middle East.
