HARRISBURG, Pa., April 15, 2014 /PRNewswire-USNewswire/ -- The Department of Environmental Protection (DEP) today announced it is awarding nearly $2.1 million in West Nile Virus (WNV) Control Program Grants to 26 counties. "These county grants ensure that mosquito populations stay in check to prevent the spread of West Nile Virus," DEP Secretary E. Christopher Abruzzo said. "Locally-based programs play an important role in protecting the public from this perennial problem." The...

Dengue fever and West Nile fever are mosquito-borne diseases that affect hundreds of millions of people worldwide each year, but there is no vaccine against either of the related viruses. A team of scientists at the University of Michigan and Purdue University has discovered a key aspect both to how the viruses replicate in the cells of their host and how they manipulate the immune system as they spread. In a study scheduled for online publication Feb. 6 in the journal Science,...

Understanding how viral proteins are produced can provide important clues on how we might interfere with the process. The group of Till Rümenapf at the University of Veterinary Medicine Vienna (Vetmeduni Vienna) has discovered that a key protease of a particular virus breaks itself down into two different functional molecules. The findings are reported in the Journal of Virology and may have important implications for the development of defence strategies against diseases caused by...

A large scale, five year study of mosquitoes from different ecological regions in Kenya, including savannah grassland, semi-arid Acacia thorn bushes, and mangrove swamps, found a reservoir of viruses carried by mosquitoes (arboviruses) that are responsible for human and animal diseases. This research, published in BioMed Central's open access journal Virology Journal, highlights the need for continued surveillance in order to monitor the risk of disease outbreaks. Over 450,000 mosquitoes...

Researchers have discovered that rising temperature induces key changes in the dengue virus when it enters its human host, and the findings represent a new approach for designing vaccines against the aggressive mosquito-borne pathogen. The researchers found that the dengue virus particles swell slightly and take on a bumpy appearance when heated to human body temperature, exposing "epitopes," or regions where antibodies could attach to neutralize the virus. The discovery is significant...

In 2010, 35 people in Greece died from a West Nile virus (WNV) outbreak, with a further 262 laboratory-confirmed human cases. A new article published in BioMedCentral's open access journal Virology Journal examines whether wild or migratory birds could have been responsible for importing and amplifying the deadly virus. WNV is a flavivirus of major public health concern, spread through the bite of infected mosquitoes. Discovered in Uganda in 1937, it was only sporadically reported up until...

Professor Sarah Butcher's research group from Helsinki University's Institute of Biotechnology report in the 24th October online issue of the journal Proceedings of the National Academy of Sciences (U.S.A.) a three-dimensional model of measles virus. The new model helps to explain many previous, unaccounted for observations in the life cycle of the virus. Measles is an important disease worldwide that is highly infectious, causing the deaths of over 100000 people annually. According to the...

Robins play a key role in transmission of West Nile virus across much of North America After its initial appearance in New York in 1999, West Nile virus spread across the United States in just a few years and is now well established throughout North and South America. Both the mosquitoes that transmit it and the birds that are important hosts for the virus are abundant in areas that have been modified by human activities. As a result, transmission of West Nile virus is highest in urbanized...

Viruses have led scientists at Washington University School of Medicine in St. Louis to the discovery of a security system in host cells. Viruses that cause disease in animals beat the security system millennia ago. But now that researchers are aware of it, they can explore the possibility of bringing the system back into play in the fight against diseases such as sudden acute respiratory syndrome (SARS), West Nile virus, dengue and yellow fever. The findings, published in Nature, solve a...

Researchers have learned the structure that results when an antibody binds to the West Nile virus, neutralizing the virus by locking up its infection mechanism. The information could help scientists develop a vaccine against the mosquito-borne disease. The findings show precisely how a key part of the antibody, called the antigen binding fragment, or Fab, attaches to two adjacent protein molecules that make up the virus's outer shell. This "crosslinking" attachment between molecules is...

Dengue fever and dengue hemorrhagic fever (DHF), caused by the dengue virus, is among the spectrum of acute febrile tropical disease and is transmitted by mosquitoes. Occurring mainly in the tropics it can be life threatening and is caused by four closely related virus stereotypes of the genus Flavivirus. It was identified and named in 1779. It has a nickname of "breakbone fever" due to it causing sever generalized bodyache. It tends to be more prevalent in the urban districts of its range...

Flavivirus is a genus of the family Flaviviridae. This genus includes the West Nile Virus, Dengue Virus, Tick-borne Encephalitis virus, yellow fever virus, and quite a few others. Flaviviruses get their name from the yellow fever virus. Flavus means yellow in Latin. Yellow fever was named because if caused yellow jaundice in victims. Mosquitoes and ticks transmit these viruses by biting people. Human infections are usually incidental since humans are unable to replicate the virus. Yellow...
