Establishment of Model Dengue mosquito

breeding free school

Dengue fever is one of the most threatening

human viral diseases transmitted by a highly

domesticated urban mosquito vector. In

prevention of transmission currently more

emphasis is given on vector control activities

through source reduction.

In collaboration with the Ministry of Education,

the National Dengue Control Unit (NDCU) has

launched an islandwide competition to select

The best dengue mosquito breeding free model school in each Medical Officer of Health (MOH)

area. This task was initiated in response to annual district proposals indicating that schools

were identified as possible breeding sites and foci

of dengue transmission in recent years,

based on entomological data. The main objective for implementation of this competition is to

inculcate the habit of removing mosquito

breeding in a continuous and sustainable manner

among school children.

Empowerment of families via school children in

vector control activities is one of the most

important activities under the strategy of social

mobilisation. To complement the elimination of

breeding places from school and domestic

environment, an Inspection card to prevent mosquito breeding was introduced recently. The progress of implementation of this activity also

will be considered as one criterion in this

competition. This competition is scheduled take place from

March to November 2015. Schools are recruited

by public health staff with the collaboration of

education authorities. In each MOH area, one

school per PHI area is to be selected by MOH/

PHI; if the health staff needs to select more than

one school in a certain PHI area, those schools

can also be included in the competition.

Public health staff is responsible for making the

school principals, teachers and students in

respective areas aware on this activity. The panel of judges at MOH level will include

the MOH, SPHI, Divisional/ Zonal Education

Officer, Divisional Environmental Officer,

member of Environment Police and

representative from Local Government . There

will be three visits by the panel of judges to each

school and a format has been developed to

allocate marks under six themes as follows. The

average score of the three visits will be

considered at the final evaluation.

Usage of the inspection card by school children in schools and their residences

for checking breeding places

Measures taken to destroy potential breeding sites regularly

Conduct of awareness raising programmes in the school

Participation of school children to inspect the mosquito breeding places at their own

residences.

Measures taken to prevent mosquito breeding during school vacation and at

the end of special functions

Any special activities carried out by the school staff and students

The final evaluation for the selection of model

school should be completed by the panel at MOH

level by 30th of September 2015.

The winners at MOH level will compete for the

district level competition; Panel of judges will be

nominated by the RDHS and should be

completed before 30th of November. This activity is aimed at promoting schools to

adapt a system of regular removal of mosquito

breeding sites. Further, empowerment of the

children is an effective way to communicate

messages to the society to bring forth the desired

behavioural change.
