Dengue is a Flaviviridae virus, with five genetic types. [8] [9] Here is the virus drawn as a 3-dimensional model of the envelope protein. [10]Dengue is in the same family as other well known viruses carried by mosquitoes that cause tropical diseases, such as yellow fever, West Nile, and Zika virus.
The symptoms of dengue resemble many other diseases including malaria, influenza, and Zika. [10] Blood tests are available to confirm the diagnosis including detecting viral RNA, or antibodies to the virus. [11] Treatment of dengue fever is symptomatic, as there is no specific treatment for dengue fever. In mild cases, treatment focuses on ...
Aedes aegypti (UK: / ˈ iː d iː z /; US: / eɪ d z / or / ˈ eɪ d iː z / from Greek αηδής 'hateful' and / eɪ ˈ dʒ ɪ p t i / from Latin, meaning 'of Egypt'), the yellow fever mosquito, is a mosquito that can spread dengue fever, chikungunya, Zika fever, Mayaro and yellow fever viruses, and other disease agents.
Dengue infection's therapeutic management is simple, cost effective and successful in saving lives by adequately performing timely institutionalized interventions. Treatment options are restricted, while no effective antiviral drugs for this infection have been accessible to date. Patients in the early phase of the dengue virus may recover ...
Epidemic dengue has become more common since the 1980s. By the late 1990s, dengue was the most important mosquito-borne disease affecting humans after malaria, with around 40 million cases of dengue fever and several hundred thousand cases of dengue hemorrhagic fever each year. Significant outbreaks of dengue fever tend to occur every five or ...
Anopheles mosquitoes can fly for up to four hours continuously at 1 to 2 km/h (0.62 to 1.24 mph), [8] traveling up to 12 km (7.5 mi) in a night. Males beat their wings between 450 and 600 times per second, driven indirectly by muscles which vibrate the thorax.
Deaths caused by the mosquito-borne dengue disease have more than tripled in Peru so far this year, according to data from the South American nation's government, which is redoubling efforts to ...
Synthetic repellents tend to be more effective and/or longer lasting than "natural" repellents. [1] [2]For protection against ticks and mosquito bites, the U.S. Centers for Disease Control (CDC) recommends DEET, icaridin (picaridin, KBR 3023), oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), IR3535 and 2-undecanone with the caveat that higher percentages of the active ingredient ...
