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. These may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin itching and skin rash. Recovery ...
Dengue fever: Dengue virus: primates mosquito bite (primarily by Aedes aegypti and Aedes albopictus) The earliest detailed descriptions of dengue-like illness appeared in medical records from 1779 to 1780, but has had a significant re-emergence in recent years (see for example 2019–20 dengue fever epidemic). Dirofilariasis: Dirofilaria spp.
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]
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 ...
Around 4 billion people, or about half the world's population, live in areas with a risk of contracting dengue, according to data from the U.S. Centers for Disease Control and Prevention.
Dengue incidence rates have risen sharply within urban areas which have recently become endemic hot spots for the disease. [61] The recent spread of Dengue can also be attributed to rapid population growth, increased coagulation in urban areas, and global travel. Without sufficient vector control, the dengue virus has evolved rapidly over time ...
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.
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 ...
