Chinese Scientists Cut Local Numbers of Dangerous Mosquito by 94%

WEDNESDAY, July 17, 2019 -- Some mosquitoes spread diseases to humans through their bite, passing along harmful pathogens like Zika, dengue fever, West Nile virus and chikungunya. Now humans are turning the tables, infecting these dangerous...

any Usutu virus (USUV), a mosquito-borne zoonotic flavivirus discovered in South Africa in 1959, has spread to many European countries over the last 20 years. The virus is currently a major concern for animal health due to its expanding host range and the growing number of avian mass mortality events. Although human infections with USUV are often asymptomatic, they are occasionally accompanied by neurological complications reminiscent of those due to West Nile virus (another flavivirus closely related to USUV). Whilst USUV actually appears less threatening than some other emergent arboviruses, the lessons learned from ...

Systemic symptoms such as joint pain, skin rash are common during the febrile stage. On the basis of only clinical presentation, it is difficult to pin-point the exact etiology for PFR. Serological investigations, polymerase chain reaction, and knowledge of concurrent epidemics in the co...

Abstract Mosquito borne diseases are a group of infections that affect humans. Emerging or reemerging diseases are those that (re)occur in regions, groups or hosts that were previously free from these diseases: dengue virus; chikungunya virus; Zika virus; West Nile fever and malaria. In Europe, these infections are mostly imported; however, due to the presence of competent mosquitoes and the number of trips both to and from endemic areas, these pathogens are potentially emergent or re-emergent. Present and future climatic conditions, as well as meteorological, environmental and demographic aspects are risk factors...

Mosquito bites may be a nuisance, but fortunately, in the U.S., they tend to amount to nothing more than that. Upon being bitten, most Americans experience a bit of swelling and itchiness, and nothing more. However, there are exceptions to this, including stronger allergic reactions to bites and cases of mosquito-borne illness.  Insect and arachnid bites, including ticks, account for approximately 2,000 cases of malaria and 30,000 cases of Lyme disease in the U.S. annually. In addition, millions of people worldwide die of malaria each year. It is helpful to protect yourself against insect bites, not only to avoid pesk...

by Thiago Nunes Pereira, Fabiano Duarte Carvalho, Silvana Faria De Mendon ça, Marcele Neves Rocha, Luciano Andrade Moreira Newly emerging or re-emerging arthropod-borne viruses (arboviruses) are important causes of human morbidity and mortality worldwide. Arboviruses such as Dengue (DENV), Zika (ZIKV), Chikungunya (CHIKV), and West Nile virus (WNV) have undergone extensive geographic expansion in the tropical and sub- tropical regions of the world. In the Americas the main vectors of DENV, ZIKV, and CHIKV are mosquito species adapted to urban environments, namelyAedes aegypti andAedes albopictus, whereas the main v...

AbstractGuillain –Barré syndrome (GBS) is an acute-onset, immune-mediated polyradiculoneuropathy, often precipitated by an antecedent infection. An association of GBS with vector-borne viral infections has been suggested, with evidence for the involvement of Zika, Dengue, Chikungunya and West Nile virus (WNV). Th is prospective case–control study was conducted to identify vector-borne viral infections in GBS. Thirteen individuals newly diagnosed as GBS were enrolled. Disease severity, prognostic factors and nerve conduction patterns were assessed. Eleven individuals with non-infectious conditions requiri...

This report summarizes surveillance data reported to CDC for 2018 on nationally notifiable arboviruses. It excludes dengue, chikungunya, and Zika viruses because they are primarily nondomestic viruses typically acquired through travel. In 2018, 48 states and the District of Columbia (DC) reported 2,813 cases of domestic arboviral disease, including 2,647 (94%) WNV disease cases. Of the WNV disease cases, 1,658 (63%) were classified as neuroinvasive disease (e.g., meningitis, encephalitis, and acute flaccid paralysis), for a national incidence of 0.51 cases of WNV neuroinvasive disease per 100,000 population. Because arbovi...

This 72-page document, updated from the 2005 edition, provides guidance to assist local, state, and territorial mosquito control programs in developing and maintaining effective mosquito control programs. The rapid spread of West Nile virus (WNV) and the emergence of other viruses such as dengue, chikungunya, and Zika in the United States and its territories, demonstrates the continuing need for organized mosquito control activities. Guidance is organized into four sections: Understanding the roles of government and nongovernmenta...
