Virus dengue

Dengue viruses are spread to people through the bite of an infected Aedes species ( Ae. aegypti or Ae. albopictus) mosquito. Dengue is common in more than 100 countries around the world. Forty percent of the world's population, about 3 billion people, live in areas with a risk of dengue. Dengue is often a leading cause of illness in areas with risk Dengue is a mosquito-borne viral infection. The virus responsible for causing dengue, is called dengue virus (DENV). There are four DENV serotypes, meaning that it is possible to be infected four times. Severe dengue is a leading cause of serious illness and death in some Asian and Latin American countries Jeden z testů (izolace viru) odděluje virus dengue v buněčných kulturách (vzorcích). Další z testů (detekce nukleových kyselin) je určen k vyhledávání nukleových kyselin viru za použití techniky zvané polymerázová řetězová reakce (PCR) Researchers have used plants to produce virus-like particles (VLPs) of the dengue virus in a potential first step towards novel vaccines against the growing threat. Dengue is a pathogenic mosquito. Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically begin three to fourteen days after infection. These may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash. Recovery generally takes two to seven days

Dengue is a pathogenic mosquito-borne virus belonging to the Flaviviridae family that causes 390 million infections per year. A safe, effective vaccine is needed because of ongoing questions about existing vaccine candidates. Dengue fever is caused by any one of four types of dengue viruses. You can't get dengue fever from being around an infected person. Instead, dengue fever is spread through mosquito bites. The two types of mosquitoes that most often spread the dengue viruses are common both in and around human lodgings

  1. The dengue virus complex consists primarily of four different dengue virus serotypes, which are roughly 65% genetically identical to each other and all members are transmitted by Aedes species mosquitoes, specifically, Aedes aegypti and Aedes albopictus, says the Mayo Clinic. In Severe Dengue cases, fatalities can occur
  2. Dengue is a viral infection spread by mosquitoes. It's widespread in many parts of the world. Mosquitoes in the UK do not spread the dengue virus. It is caught by people visiting or living in Asia, the Americas or the Caribbean

Dengue virus is prevalent throughout the tropics and subtropics

Dengue viral infections are one of the most important mosquito borne diseases in the world. They may be asymptomatic or may give rise to undifferentiated fever, dengue fever, dengue haemorrhagic fever (DHF), or dengue shock syndrome. Annually, 100 million cases of dengue fever and half a million cases of DHF occur worldwide. Ninety percent of DHF subjects are children less than 15 years of age Dengue virus may be passed from a mother to her unborn baby.

Dengue virus is a flavivirus belonging to the family Flaviviridae. Its principal vector is Aedes aegypti, a highly urbanized, daytime-biting mosquito that breeds in stored water. There are 4 antigenetically variant serotypes of dengue virus, DEN-1 to DEN-4, and type-specific immunity against one serotype cannot block infection with another. Dengue fever is a viral disease that is spread by infected mosquitoes. Infection with the dengue virus can cause severe flu-like symptoms. In some cases it leads to dengue haemorrhagic fever, also known as severe dengue, which affects the body's vascular system (how blood moves through the body) Dengue fever is a disease spread by the Aedes aegypti mosquito and is caused by one of four dengue viruses.
