Severe dengue has a higher risk of death when not managed appropriately. Of complications associated with severe bleeding, organ impairment and/or plasma leakage.

Although less common, some people develop severe dengue, which can be any number This can range from subclinical disease (people may not know they are even infected) to severe flu-like symptoms in those infected. Dengue is widespread throughout the tropics, with local variations in risk influenced by climate parameters as well as social and environmental factors.ĭengue causes a wide spectrum of disease. Mosquitoes are also vectors of chikungunya, yellow fever and Zika viruses. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. Occasionally this develops into a potentially lethal complication, called severe dengue.ĭengue is a mosquito-borne viral disease that has rapidly spread to all regions of WHO in recent years.

While many DENV infections produce only mild illness, DENV can cause an acute flu-like illness.

Sustained community involvement can improve vector control efforts substantially.

Dengue prevention and control depends on effective vector control measures.

Although an estimated 100-400 million infections occur each year, over 80% are generally mild and asymptomatic.

The global incidence of dengue has grown dramatically with about half of the world's population now at risk.

Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas.

Early detection of disease progression associated with severe dengue, and access to proper medical care lowers fatality rates of severe dengue to below 1%.

There is no specific treatment for dengue/severe dengue.

It requires management by medical professionals.

Severe dengue is a leading cause of serious illness and death in some Asian and Latin American countries.

There are four DENV serotypes and it is possible to be infected four times.

The virus responsible for causing dengue, is called dengue virus (DENV).

The primary vectors that transmit the disease are Aedes aegypti mosquitoes and, to a lesser extent, Ae. Dengue is a viral infection transmitted to humans through the bite of infected mosquitoes.
