What are the main causes of dengue fever?

the substances that cure dengue fever

Cause: Mosquito
Cure: none

Fact Sheet: Dengue and Dengue Hemorrhagic Fever
CLINICAL FEATURES

Sudden onset of fever, severe headache, myalgias and arthralgias, leukopenia, thrombocytopenia and hemorrhagic manifestations
Occasionally produces shock and hemorrhage, leading to death
ETIOLOGIC AGENT

Dengue viruses (DEN-1, DEN-2, DEN-3 and DEN-4) - flaviviruses
INCIDENCE

Variable, depending on epidemic activity.
Globally, there are an estimated 50 to 100 million cases of dengue fever (DF) and several hundred thousand cases of dengue hemorrhagic fever (DHF) per year
Average case fatality rate of DHF is about 5%
In 1995, 250,000 cases of DF and 7,000 cases of DHF reported in Americas
Between 100 to 200 suspected cases introduced into U.S. each year by travelers
SEQUELAE

None
COSTS

$250 million estimated in Puerto Rico in past 10 years
TRANSMISSION

Mosquito-borne (Aedes aegypti)
RISK GROUPS

Residents of or visitors to tropical urban areas
Increased severe and fatal disease in children under 15 years
No cross-immunity from each serotype
A person can theoretically experience four dengue infections
SURVEILLANCE

Active, laboratory-based surveillance in Puerto Rico and the U.S. Virgin Islands
In U.S., passive surveillance of imported cases reported to CDC and other reference laboratories
Laboratory-based, passive surveillance in endemic areas
TRENDS

Resurgent disease worldwide in the tropics
Epidemics are larger and more frequent
Transmission in continental U.S. in 1995; first since 1986
Since first epidemic in 1981, DHF now reported from 18 countries in the Americas
Evolution of disease pattern in Americas similar to SE Asia in 1950s and 1960s
CHALLENGES

Increased incidence associated with increased urbanization
Rapid dispersal of viruses via air travel
Emergency control methods ineffective
Severe hemorrhagic disease poorly understood by physicians in Americas
Change emphasis from emergency response to prevention of epidemics
Develop better government-based programs
Encourage community participation in prevention and control programs
OPPORTUNITIES

Dengue Branch, NCID, designated WHO Reference Center
Improve laboratory-based international surveillance
Educate medical community
Develop community-based, integrated prevention programs
RESEARCH PRIORITIES

Develop improved laboratory-based international surveillance
Develop rapid, sensitive and specific diagnostic tests
Develop more effective community-based prevention programs
Develop tetravalent dengue vaccine

the cause of that was the stagnant water and dirty surroundings

i had just confined because of that... causes? mosquito bringing dengue.... substances that cure? it is what we call tawa-tawa, it will be boiled then drunk by the patient repeatedly...

WATER

Dengue is transmitted to humans by the Aedes aegypti (rarely Aedes albopictus) mosquito, which feeds during the day.
