OF AEDES-AEGYPTI ON MAN. This represents a reduction of 73%. Patients with dengue should seek medical advice upon the appearance of warning signs. J Infect Chemother 2006;12:396-8. Risk of mosquito infection is positively associated with high viremia and high fever in the patient; conversely, high levels of DENV-specific antibodies are associated with a decreased risk of mosquito infection (Nguyen et al 2013 PNAS). The incidence of dengue has grown dramatically around the world in recent decades. 2014; 1032 dengue deaths were also reported in the region.

Severe dengue has a higher risk of death when not managed appropriately. Dengue should be suspected when a high fever (40°C/104°F) is accompanied by 2 of the following symptoms during the febrile phase: A patient enters what is called the critical phase normally about 3-7 days after illness onset. Dengue is a mosquito-borne disease caused by any one of four dengue viruses. C., et al., Maternal and foetal The World Health Organization classifies dengue into 2 major categories: dengue (with / without warning signs) and severe dengue. Dengue fever is a viral flu which is spread by the bite of an Aedes mosquito. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. for hospital admission, ensuring close observation, and to minimise the risk of developing the more severe dengue (see below). The presence of IgM is indicative of a recent DENV infection. viremic for about 4-5 days, but viremia can last as long as 12 days [13]. There are commercially-produced rapid diagnostic tests available for this, because it takes only ~20 mins to determine the result, and the test does not require specialized Symptoms typically begin three to fourteen days after infection. Dengue causes a wide spectrum of disease. (RT-PCR). Individuals, whether vaccinated Symptoms usually last for 2–7 days, after an incubation period of 4–10 days after the bite from an infected mosquito [25].

Mosquitoes in the UK do not spread the dengue virus. Virus may be circulating in the blood during this time, and therefore you may transmit the virus to new uninfected mosquitoes, who may in turn infect other This is achieved through: In addition, there is ongoing research amongst many groups of international collaborators in search of novel tools and innovative strategies that will contribute in global efforts to interrupt transmission of dengue, as well as other mosquito-borne diseases. Bulletin of the World Health Organization, 1973. Dengue fever is a severe, flu-like illness that affects infants, young children and adults, but seldom causes death.Dengue should be suspected when a high fever (40°C/104°F) is accompanied by 2 of the following symptoms: severe headache, pain behind the eyes, muscle and joint pains, nausea, vomiting, swollen glands or rash.
