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 ...
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, posing challenges to both government and public health officials. [62] Malaria is caused by a protozoan called Plasmodium ...
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 mosquito-borne virus has a long history in warm climates but is now also emerging in regions where it had been generally unheard of—such as in Europe and parts of the U.S.
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.
Dengue fever is usually not fatal, but infection with one of four serotypes can increase later susceptibility to other serotypes, resulting in a potentially fatal disease called severe dengue. [40] Dengue fever is caused by a flavivirus which is spread mostly by the bite of the Aedes aegypti mosquito. [40] No treatment for either dengue or ...
A major outbreak in Argentina of dengue, a mosquito-borne illness that can be fatal, is on track to smash previous records, reflecting wider worry around South America where warmer and wetter ...
Dengue fever is an infectious disease caused by dengue viruses known to be in the tropical regions. [49] It is transmitted by the mosquito Aedes, or A. aegypti. [50] Dengue incidence has increased in the last few decades and is projected to continue to do so with changing climate conditions. [51] Dengue can be fatal.
