  • A: It sounds like you are referring to the chikungunya virus. (patriotledger.com)
  • Chikungunya (which means "stooped walk" in a Tanzanian language, named because the joint pain from it makes people walk in a bent over fashion) is a viral illness transmitted by infected mosquitoes (only certain types of mosquitoes can carry this virus). (patriotledger.com)
  • although I am unaware of any cases transmitted from infected mosquitoes within the U.S., the types of mosquitoes that can carry this virus do exist here, so it is likely just a matter of time until there are cases of chikungunya acquired within the U.S. borders. (patriotledger.com)
  • It is thought that most people infected with chikungunya develop symptoms within two days to two weeks after the virus is transmitted from the bite of an infected mosquito, although some studies after outbreaks in Africa have shown that up to 50 percent of people who were infected, as demonstrated by antibodies to the virus in their blood tests, did not report any symptoms. (patriotledger.com)
  • however, other diseases, such as dengue fever, may have similar symptoms (and indeed dengue fever may be transmitted by the same types of mosquitoes and in the same geographic areas as chikungunya), so definitive diagnosis may be challenging. (patriotledger.com)

  • Recombinant domains of the E protein are used as well-defined antigens in the serological detection of antibodies directed against dengue virus and as immunogens in vaccine candidates. (wikipedia.org)
  • The test is automatically done on all samples testing positive or equivocal for La Crosse Virus IgM antibodies by ELISA. (wikipedia.org)
  • bacteria
  • The origins of viruses in the evolutionary history of life are unclear: some may have evolved from plasmids-pieces of DNA that can move between cells-while others may have evolved from bacteria. (phys.org)
  • insects

  • Dengue fever is a disease caused by one of a number of viruses that are carried by mosquitoes. (thefreedictionary.com)
  • Five serotypes of the virus have been found, all of which can cause the full spectrum of disease. (wikipedia.org)
  • The disease occurs most often during the rainy season in areas with high numbers of infected mosquitoes. (wikipedia.org)
  • During the latter half of the 20th century, Dengue fever reemerged as a global disease, with the virus spreading geographically due to urbanization, population growth, increased international travel, and global warming, and continues to cause at least 50 million infections per year, making Dengue fever the most common and clinically important arboviral disease. (wikipedia.org)
  • They can transmit disease without being affected themselves. (wikipedia.org)
  • The mechanism of transmission of this disease starts with the injection of the parasite into the victim's blood when malaria-infected female Anopheles mosquitoes bite into a human being. (wikipedia.org)
  • Generally CNPV is considered a disease of songbirds, such as canaries, magpies and nightingales, and is associated with higher mortality rates when compared to other avian pox viruses. (wikipedia.org)

  • infections
  • Officials, perplexed, are now wondering why they were so worried about a virus where the vast majority of infections are completely asymptomatic and without any detectable consequence. (almanacnews.com)
  • Most JE virus infections are asymptomatic, or appear to be mild. (news-medical.net)
  • Taking this into consideration, Doherty and Zinkernagel were working on the response of mice to virus infections. (wikipedia.org)
  • spread
  • Currently, no vaccine or treatment protects against dengue, so the only way to stop its spread is by controlling mosquitoes. (bio-medicine.org)
  • Influenza viruses are spread by coughing and sneezing, and others such as norovirus, are transmitted by the faecal-oral route, when they contaminate hands, food, or water. (phys.org)
  • occurs
  • After the virus has been transmitted to the human host, a period of incubation occurs. (thefreedictionary.com)
  • It also occurs throughout the summer (May until September), or even throughoput the year rather than mostly in August, which may be due to the diversity of mosquitoes it can infect. (wikipedia.org)

  • grows
  • Dengue virus grows and spreads in mosquitoes faster at higher temperatures, but slows when temperatures are lower or fluctuate, suggesting that local weather conditions could have a big influence on dengue fever outbreaks. (phys.org)
  • infects
  • Recent findings suggest that, as the virus infects human cells, host homeostatic processes like autophagy and ER stress response, not to mention apoptosis, are triggered depending on the infected cell type. (wikipedia.org)
  • hosts
  • A new study finds that viruses share some genes exclusively with cells that are not their hosts. (phys.org)
