What is Dengue Fever?

Dengue is a mosquito-borne infection that in recent decades has become a major international public health concern. Dengue is found in tropical and sub-tropical regions around the world, predominantly in urban and semi- urban areas.

Dengue Fever is now endemic in more than 100 countries in Africa, the Americas, the Eastern Mediterranean, South-east Asia and the Western Pacific. South-east Asia and the Western Pacific are the most seriously
affected.

The incidence of dengue has grown dramatically around the world in recent decades. Some 2.5 billion people – two fifths of the world’s population – are now at risk from dengue. WHO currently estimates there may be 50 million dengue infections worldwide every year.

An estimated 500 000 people with DHF require hospitalization each year, a very large proportion of whom are children. About 2.5% of those affected die.

Transmission

You can get dengue virus infections from the bite of an infected Aedes mosquito.

Mosquitoes become infected when they bite infected humans, and later transmit infection to other people they bite.

Dengue is not contagious from person to person.

Diagnosis

Blood tests – thrombocytopenia and relative leukopenia – low platelet and white blood cell count

The diagnosis of dengue is usually made clinically. The classic picture is high fever with no localizing source of infection, a petechial rash, vomiting blood, or bloody diarrhea.

Tourniquet test

Treatment

Close monitoring of vital signs in critical period (between day 2 to day 7 of fever) is vital. Increased oral fluid intake is recommended to prevent dehydration.

A platelet transfusion is indicated in rare cases if the platelet level drops significantly or if there is significant bleeding. The presence of melena may indicate internal gastrointestinal bleeding requiring platelet and/or red blood cell transfusion.

Patients may receive paracetamol preparations to deal with these symptoms if dengue is suspected (people with dengue fever is advised not to take aspirin).
