Dengue fever is the fastest emerging arboviral infection spread
by Aedes mosquitoes with major public health consequences in
over 100 tropical and sub-tropical countries in South-East Asia,
the Western Pacific, and South and Central America. Up to 2.5
billion people globally live under the threat of dengue fever and its
severe forms—dengue hemorrhagic fever (DHF) or dengue shock
syndrome (DSS). More than 75% of these people, or approximately
1.8 billion, live in the Asia-Pacific Region. As the disease spreads to
new geographical areas, the frequency of the outbreaks is increasing
along with changing disease epidemiology. It is estimated that 50
a million cases of dengue fever occur worldwide annually and half a
million people suffering from DHF require hospitalization each year,
a very large proportion of whom (approximately 90%) are children
less than five years old. About 2.5% of those affected with dengue
die of the disease.

Dengue is a viral infection transmitted by mosquitoes that infects around 100-400 million people annually worldwide. It is caused by the dengue virus of which there are 4 serotypes. Infection with one type provides lifelong immunity to that type but subsequent infections with other types increase the risk of severe dengue. The disease ranges from mild fever to life-threatening dengue hemorrhagic fever/dengue shock syndrome. There is no vaccine for dengue prevention currently.
Dengue fever update
Dengue fever is caused by the dengue virus, which is transmitted by mosquitoes. There are four types of the virus. Infection causes flu-like symptoms but can develop into severe dengue hemorrhagic fever in some cases. While most cases resolve on their own, severe cases involve bleeding, low platelet counts, and shock and can be fatal if not properly treated. Recurrent infection with a different virus type increases the risk of more severe disease. Prevention relies on controlling mosquito populations and avoiding bites.

- 5. Transmission Cycle The female usually becomes infected with the dengue virus when it takes a blood meal from a person during the acute febrile (viremia) phase of dengue illness. After an extrinsic incubation period of 8 to 10 days, the mosquito becomes infected. The virus is transmitted when the infected female mosquito bites and injects its saliva into the wound of the person bitten.
- 6. The cycle of dengue continues by this process. Dengue begins abruptly after an intrinsic incubation period of 4 to 7 days (range 3–14 days). There is also evidence of vertical transmission of dengue virus from infected female mosquitoes to the next generation.
