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 ...

Jan 30, 2025 · Dengue viruses are usually spread to people through the bites of infected Aedes species mosquitoes. A woman infected with dengue during pregnancy can pass the virus to her fetus. Rarely, dengue can be spread through other routes.

Apr 23, 2024 · Prevention and control of dengue depend on vector control. There is no specific treatment for dengue/severe dengue, and early detection and access to proper medical care greatly lower fatality rates of severe dengue. Dengue (break-bone fever) is a viral infection that spreads from mosquitoes to people.

Dengue viruses circulate mainly between human and vector mosquitoes, and the vector presence is a limiting factor of transmission. Therefore, spatial distribution of dengue vectors is a significant concern in the epidemiology of the disease.

DENV infection causes dandy fever, breakbone fever, and dengue hemorrhagic fever; and in severe cases, dengue shock syndrome has occurred. The rainy season is the most favorable climate for DENV infection outbreaks in tropical countries in Asia and South America.

Of these species, the primary vector of the dengue virus is the species Aedes aegypti. It is the principal dengue vector responsible for dengue transmission and dengue epidemics.

Effective vector control measures are critical to achieving and sustaining reduction of morbidity attributable to dengue. Preventive and vector control interventions aim to reduce dengue transmission, thereby decreasing the incidence of the infection and …

VECTOR OF DENGUE. Aedes mosquitoes are a vector of dengue fever. It is a small mosquito, black with white stripes and is approximately 3-5 mm in size. It takes about 7 to 8 days to develop the virus in its body and transmit the disease; Feeding Habit . Day biter; Mainly feeds on human beings in domestic and peri domestic situations.

Aug 18, 2016 · Dengue is widespread throughout the tropics and local spatial variation in dengue virus transmission is strongly influenced by rainfall, temperature, urbanization and distribution of the principal...

Dengue is a vector-borne viral disease caused by the flavivirus dengue virus (DENV). Approximately 400 million cases and 22 000 deaths occur due to dengue worldwide each year. It has been reported in more than 100 countries in tropical and subtropical regions.
