responsible for the coordination of control and preventive activities related to dengue at
central level between different stakeholders.
Our Vision
Tominimize the health, economic and social impact of the disease by reversing the rising
trend of dengue
Our Mission
To enhance the capacity at the national, Provincial, district and divisional levels for
better planning, prediction and early detection and prompt control and
containment of outbreaks and epidemics through partnerships and application of
coordinated efforts in a sustainable manner

01.Introduction
Dengue fever has emerged as the leading public health problem with expanding
geographical boundaries and severity. The mosquito Aedes aegypti and Aedes
albopictus are the two vectors of dengue illness which breed mainly in water
holding containers in domestic and peri-domestic localities.
The National Dengue Control Unit is the focal point for the national dengue control
programme in Ministry of Health, Sri Lanka. It was established in year 2005 as a
decision taken by the Ministry of Health following the major DF/DHF outbreak in
year 2004. It is responsible for the coordination and implementation of dengue
control / prevention activities with different stakeholders.

Profile of the National Dengue Control Unit
Goal: To reduce endemicity to such an extent that it is no longer a major public
health problem in Sri Lanka.
General objective: To reduce morbidity and mortality due to dengue fever (DF)
and dengue haemorrhagic fever (DHF) by 50% of that in 2009, by 2015.
Specific objectives:
To increase the capacity of the health sector to monitor trends and reduce
dengue transmission
To strengthen the capacity to implement effective integrated vector
management.
To increase health workers capacity to diagnose and treat patients and
improve health-seeking behaviour of communities
To promote collaboration among communities, national health agencies and
stakeholders to implement dengue programmes for behavioural change
To increase the capacity to predict, detect early and respond to dengue
outbreaks
To address programmatic issues and gaps that requires new or improved
tools for effective dengue prevention and control

02. Disease Surveillance
Epidemiological (disease) surveillance is carried out through the Epidemiology
Unit and data is communicated to National dengue control Unit to monitor
control activities in RDHS and divisional levels. A web based surveillance in
collaboration with the Epidemiology Unit has established in 50 sentinel
hospitals in 2013.It has been further expanded by providing access to MOOH.
In 2013 a total of 31,200 dengue cases were reported from the entire country.
Although the number of cases were high in 2012, the number of deaths were
89 with a case fatality rate of 0.28 which was a marked reduction compared to
previous years (Table 1).

Reported incidence by districts - 2013
Figure 1
Two distinct peaks of case reporting in May July and Oct Jan are identified
over the years associated with South-West and North-East monsoon rains
respectively. Therefore it is evident that preventive activities should be initiated
before the increase of cases as such, bi-annual mosquito control weeks are
conducted in April and September.

Vector surveillance is important to forecast possible outbreaks and initiate early
measures to prevent the occurrence of outbreaks and to limit the spread. Vector
indices are calculated (Breteau Index-BI, Premise index-PI and Container Index-
CI) for assessment of risk and impact of control activities.
In 2013 a total of 185,090 premises were inspected, where Aedes larvae were
found positive in 15,860(8.6%)containers. The types of examined containers are
illustrated below (Figure 6).

health authorities with all relevant stakeholders and the community in accordance
with the guidelines of the Ministry of Health . Vector control activities are carried
out on a high risk approach based on epidemiological and entomological
parameters.
Vector Control activities are conducted through the field health staff attached to
the Medical Officer of Health offices in the country in collaboration with the
Regional Malaria officers (RMO) Medical officer AFC, entomologists and their
teams at district level

03. Case Management
During 2013, curative health care personal were trained on proper management of
dengue patients based on National guidelines coordinated by the Epidemiology
Unit and Education, Training & Research unit, Ministry of Health.
Management of dengue cases was further enhanced by establishing 24 new High
Dependency Units (HDU) in selected hospitals. In addition equipments for existing
HDUs were also provided during 2013.

Harnessing activities at district & divisional level
Emergency response includes measures to reduce the number of infective
mosquitoes rapidly and proper management of patients
Based on notification,
Early detection of increasing fever cases at treatment facilities Analyze data by district/ MOH areas/smaller localities Anticipating/predicting outbreaks using surveillance data Use of entomological surveillance data timely to forecast / Identify high risk
areas Develop plans for vector control Set targets Identify strategies/ resources Monitoring & evaluation

06. Research
One of the major research activities done by the National dengue Control unit is
conducting a research on Effectiveness of using Bacillus thuringiensis israelensis
briquette formulation (Mosquito dunk) in Dengue control and Prevention activities
in selected MOH areas in the Western Province Sri Lanka.
An interventional study with pre and post intervention (Application of Bti dunks)
observations and with control to the experiment was done in selected MOH aeras
in Colombo and Gamaha RDHS areas. Vector densities and incidence of dengue
cases were compared as outcome variables before and after the intervention
within the individual intervention areas and in comparison to selected control
areas.
Majority (>60%) of potential and positive breeding places were removable and
there were no places for application of mosquito dunks in all study areas. Places
where mosquito dunks can be applied remained few in number throughout and
there was no considerable difference in container index or Breteau index even
after application of Bti dunks in comparison to the same in controled areas. Of the
households that have received the dunks, majority have applied them into roof
gutters drains or gullies.
The cost of application of mosquito dunk through health system is enormous.
