Dengue: An Alarming Disease



Dengue is one of the most common vector-borne diseases in Southeast Asia, and has been ranked as the most important mosquito-borne viral disease with epidemic potential in the world.

After reporting more than 100,000 dengue fever cases in 2016, Malaysia's dengue fever case count continues into 2017.

It is an infectious disease carried by mosquitoes and caused by any of four related dengue viruses. There are four closely related but antigenically different serotypes of the virus that can cause dengue (DEN1, DEN 2, DEN 3, DEN 4).

Mosquitoes are among the deadliest animals in the world. Their ability to carry and spread disease to humans causes millions of deaths every year. 
 People get the dengue virus from the bite of an infected Aedes mosquito. 
This disease used to be called “break-bone fever” because it sometimes causes severe joint and muscle pain that feels like bones are breaking.

There are three types of dengue fever in order of less severe to most: the typical uncomplicated dengue fever (DF), dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS).

The World Health Organization (WHO) estimates there may be 50–100 million dengue infections worldwide every year. However, new research from the University of Oxford and the Wellcome Trust, using cartographic approaches, estimate there to be 390 million dengue infections per year worldwide.
