West Nile virus is also on the list

In Caldwell, Idaho, on the Snake River in Western Idaho, Dr. Carolyn Rees tells us that she was at ground zero during a West Nile Virus epidemic “leaving many people with post-encephalitic brain damage”. A review of the research literature on WNV includes a number of studies now documenting enduring memory and other cognitive losses as a predictable outcome of a WNV infection. The prevalence of this kind of virus (an “arborvirus”) is growing continuously in the US. The disease is primarily spread via mosquito-transmitted infections in birds. Where the disease has had a long history, some mammals are also commonly infected (e.g., in Northern Africa, where this plague originated, nearly 100% of horses have WNV antibodies marking a historic infection; tragically, in the U.S., the disease kills about 40% of infected horses). The incidence of WNV shall continue to grow as a source of neurological impairment in American populations as it slowly spreads across our landscape. We have to add it to our list of those factors that contribute to our potentially losing our marbles at a younger-than-deserved age! A final comment: Especially if you live in a dryer climate (like that beautiful irrigated farming area above the Snake River Canyon in Caldwell) where the species of mosquitoes that transmit the virus thrive, give some thought to mosquito abatement and the use of repellent when mosquitos are in bloom. Finding an otherwise-healthy-looking dead bird [talk abou...

Ongoing destruction of nature will result in stream of animal diseases jumping to humans, says reportCoronavirus – latest updatesSee all our coronavirus coverageThe world is treating the health and economic symptoms of the coronavirus pandemic but not the environmental cause, according to the authors of aUN report. As a result, a steady stream of diseases can be expected to jump from animals to humans in coming years, they say.The number of such“zoonotic” epidemics is rising, from Ebola to Sars to West Nile virus and Rift Valley fever, with the root cause being the destruction of nature by humans and the ...

anová V, Csank T Abstract West Nile virus (WNV) is a mosquito-borne flavivirus (the genus Flavivirus) representing a medical and veterinary public health concern. Birds are the most important reservoirs. Culicine mosquitoes transmit WNV to vertebrate hosts (including horses and humans) and migratory birds play role in its long-distance transport. Slovakia is geographically localised at the crossroad of migration routes connecting South Europe and Africa with breeding localities in the Western, Northern, Central and Eastern Europe and Siberia. This review summarizes historical and present knowledge...

by Chuan-min Zhou, Jian-wei Liu, Rui Qi, Li-zhu Fang, Xiang-rong Qin, Hui-ju Han, Rong-can Mo, Hao Yu, Yong-jun Jiao, Jian-yan Lin, Xue-jie Yu Currently, Zika virus (ZIKV) is spreading across the world and no ZIKV infection cases have ever been reported in China. Here, we aimed to determine whether ZIKV infection exists in China. Blood samples of 273 healthy individuals were collected from Nanning City, Guangxi Province, China in March 2 019. We found that 9.5% (26/273) and 1.8% (5/273) of healthy persons were positive to ZIKV total antibody (IgG and/or IgM) IgM antibody, respectively. All ZIKV positive plasma samples wer...

Conclusions/SignificanceThe findings of our study are of major concern for mosquito control programs in Europe, that rely on the use of a limited number of available larvicides, and highlight the necessity for the development of appropriate Insecticide Resistance Management (IRM) programs, to ensure the sustainable use of DFB.

ws Werner In 2018, West Nile virus (WNV) broke out for the first time in Germany, with continuation of the epidemic in 2019, involving birds, horses and humans. To identify vectors and characterize the virus, mosquitoes were collected in both years in zoological gardens and on a horse meadow immediately following the diagnosis of disease cases in birds and horses. Mosquitoes were identified and screened for WNV by qRT-PCR, with virus-positive samples being sequenced for the viral envelope protein gene. While no positive mosquitoes were found in 2018, seven mosquito pools tested positive for WNV in 2019 in the Tierpa...

This study highlights the risk of a further spread in Germany in the next years with additional human WNV infections. Thus, surveillance of birds is essential to provide an early epidemic warning and thus, initiate targeted control measures.

Montgomery The genus Flavivirus contains many mosquito-borne human pathogens of global epidemiological importance such as dengue virus, West Nile virus, and Zika virus, which has recently emerged at epidemic levels. Infections with these viruses result in divergent clinical outcomes ranging f...

In this study, logistic mixed models were used to identify associations between the landscape, human population, and WNV-infected Culex quinquefasciatus mosquitoes during the 2012 WNV epidemic in Dallas Co. We found increased probabilities for WNV-positive mosquitoes in north and central Dallas Co. The most significant predictors of the presence of WNV in Cx. quinquefasciatus pools were increased urbanization (based on an index composed of greater population density, lower normalized difference vegetation index, higher coverage of urban land types, and more impervious surfaces), older human populations, and lower elevation...

Yes. However, very probably not because of the novel coronavirus that has appeared in China. This seems to be front page headlines in every media outlet on the planet, and  the World Health Organization has convened a meeting to decide whether to declare an official Global Health Emergency.This sort of flapdoodle happens every time a novel pathogen appears. Back when I lived in the Hub of the Universe a mosquito-borne disease called West Nile virus appeared (having formerly been large confined to, yes, west of the Nile). For weeks, every time a new case was identified it would be on the front page of the Boston Globe....

Its evolution into local or even widespread epidemics is driven by multiple factors from genetic diversification of the virus to environmental conditions.
