Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]
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.
Dengue fever is caused by infection through viruses of the family Flaviviridae. The illness is most commonly transmitted by Aedes aegypti mosquitoes in tropical and subtropical regions. [58] Dengue virus has four different serotypes, each of which are antigenically related but have limited cross-immunity to reinfection. [59]
The symptoms experienced by those infected with dengue can vary widely: up to 80% of dengue cases are asymptomatic, and while some infections may trigger only flu-like symptoms, more serious cases ...
The Department of Agriculture also is looking at a possible outbreak at a Spokane rescue organization.
Dengue fever is a mosquito-borne disease caused by dengue virus, prevalent in tropical and subtropical areas. It is frequently asymptomatic; if symptoms appear, they typically begin 3 to 14 days after infection.
Skin conditions in dogs are very common, so it's important to recognize the symptoms and understand the factors that cause them. Dr. Rebecca MacMillan, a vet with over 15 years of experience, says ...
For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus. Although invertebrate-transmitted diseases pose a particular threat on the continents of Africa, Asia and South America, there is one way of controlling invertebrate-borne diseases, which is by controlling the invertebrate vector.
