After reporting 32,063 cases dengue fever cases in 2013, The Sri Lanka Communicable Diseases Unit stated that 46,584 cases were reported in 2014, an increase of 14,521 cases.


Of the more than 46,000 cases reported last year, 95 fatalities were seen, or less than 1%.

In December 2014 alone, 4600 cases were reported, according to the Sri Lanka Health Ministry.

The high numbers in 2014 are being attributed to heavy rains during the end of the year and wet weather throughout. The capital of Colombo was hit especially hard.

The 2014 total is the highest reported in the country in the past five years.

The 1st serologically confirmed dengue case in Sri Lanka was reported in 1962, and the 1st documented dengue outbreak occurred in 1965-1966. Since that time, dengue fever has been a problem in the country.

Dengue fever is a disease caused by any one of four closely related dengue viruses (DENV 1, DENV 2, DENV 3, or DENV 4). The viruses aretransmitted to humans by the bite of an infected Aedes mosquito.

The principal symptoms of dengue fever are high fever, severe headache, severe pain behind the eyes,joint pain, muscle and bone pain, rash, and mildbleeding (e.g., nose or gums bleed, easy bruising). Generally, younger children and those with their first dengue infection have a milder illness than older children and adults.

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.
