Bedeviled By Dengue
Bedeviled By Dengue
Dengue is a mosquito-borne infection found in tropical and sub-tropical regions around the world. In recent years, transmission has increased predominantly in urban and semi-urban areas and has become a major international public health concern.
Severe dengue (also known as Dengue Haemorrhagic Fever) was first recognized in the 1950s during dengue epidemics in the Philippines and Thailand. Today, severe dengue affects most Asian and Latin American countries and has become a leading cause of hospitalization and death among children in these regions.
The Aedes aegypti mosquito is the primary vector of dengue. The virus is transmitted to humans through the bites of infected female mosquitoes. After virus incubation for 4–10 days, an infected mosquito is capable of transmitting the virus for the rest of its life.
Infected humans are the main carriers and multipliers of the virus, serving as a source of the virus for uninfected mosquitoes. Patients who are already infected with the dengue virus can transmit the infection (for 4–5 days; maximum 12) via Aedes mosquitoes after their first symptoms appear.

The Aedes aegypti mosquito lives in urban habitats and breeds mostly in man-made containers. Unlike other mosquitoes, Ae. aegypti is a daytime feeder; its peak biting periods are early in the morning and in the evening before dusk. Female Ae. aegyptibites multiple people during each feeding period.

Dengue should be suspected when a high fever (40°C/ 104°F) is accompanied by two of the following symptoms: severe headache, pain behind the eyes, muscle and joint pains, nausea, vomiting, swollen glands or rash. Symptoms usually last for 2–7 days, after an incubation period of 4–10 days after the bite from an infected mosquito.

Severe dengue is a potentially deadly complication due to plasma leaking, fluid accumulation, respiratory distress, severe bleeding, or organ impairment. Warning signs occur 3–7 days after the first symptoms in

    West Nile virus is a disease transmitted by certain mosquitoes that carry a disease that can cause serious brain inflammation. West Nile Virus originated in Uganda, in 1937.

    What’s the first thing that comes to mind when you hear the words ‘yellow fever’? People who alters to the color yellow? An incurable disease that can cause self-destruction? Yes and no. The keyword here is ‘mosquitoes’. That’s right, tiny mosquitoes that carry a virus around to their victims.

    Dengue Fever is caused by one of the four closely related, but antigenically distinct, virus serotypes Dengue type 1, Dengue type 2, Dengue type 3, and Dengue type 4 of the genus Flavivirus and Chikungunya virus. Infection with one of these serotype provides immunity to only that serotype of life, to a person living in a Dengue-endemic area can have more than one Dengue infection during their lifetime. Dengue fever through the four different Dengue serotypes are maintained in the cycle which involves humans and Aedes aegypti or Aedes albopictus mosquito through the transmission of the viruses to humans by the bite of an infected mosquito. The mosquito becomes infected with the Dengue virus when it bites a person who has Dengue and after a week it can transmit the virus while biting a healthy person. Dengue cannot be transmitted or directly spread from person to person. Aedes aegypti is the most common aedes specie which is a domestic, day-biting mosquito that prefers to feed on humans.…
