Strengthening Social Mobilization For

Dengue Control

Dengue fever is a vector borne viral disease which

may lead to serious consequences unless it is managed

appropriately. Dengue is endemic in Sri Lanka and

local epidemics had been reported in the recent past.

Strategies adapted to control dengue are namely

vector surveillance & integrated vector control,

disease surveillance, case management, Social

mobilization(SM) & inter-sectoral coordination,

outbreak response and research. SM has a major role

to play to enhance positive behaviour towards

elimination of mosquito breeding places throughout

the country.

SM is a process that raises awareness and motivates

people to demand change or a particular development.

It is mostly used by social movements in grassroots

groups, governments and political organizations to

achieve a particular goal. With regard to dengue, this

concept is used in bridging together all feasible and

practical inter sectorial partners to raise peoples

awareness and behavior for dengue prevention and

control to assist in the delivery of resources and

services, and to strengthen community participation

for sustainability and self-reliance. The ultimate goal

of SM is to achieve an expected sustainable positive

change in the environment by continuous

encouragement and empowerment of the masses. The

important action areas that had been identified in view

of SM are frequent and regular inspection and

removal of dengue mosquito breeding sites in

sustainable manner. To make this a success, a

presidential task force (PTF) was established.

Relevant ministries were given a mandate to perform

their activities in aligning with dengue control strategy

on IVM at provincial, district, divisional levels. An

integrated plan had been developed with the

contribution of the all stake holders to eliminate the

possible breeding sites in government, private

institutions, public places, religious places,

households, construction sites, etc.

All the activities are expected to implement at grass

root level in a well-coordinated manner. The health

sector bears the overall responsibility in provision of

technical guidance. The organization structure of the

PTF is as follows (Fig 1)

The activities carried out under SM are awareness

raising programmes such as distribution of IEC

materials, organization of public activities such as art

competitions, street dramas, mass media & local

media advertisements, declaration of dengue

weeks/days. Also SM includes advocacy of relevant

parties, monitoring and evaluation of these activities.

Island wide dengue week is declared from 26 March

to 1st of April before the onset of South Western moon

soon as part of SM this year in order to prevent

dengue outbreak.

The activities carried out under SM will play a

significant role in achieving the target of control of

dengue in Sri Lanka.
