Education and Training Intervention for Prevention and Control of Mosquito Larva and Dengue Feverin Banleuam Sub-District, Muang District, Udonthani Province

Abstract

This study implemented an education and training in tervention to reduce the
incidence of dengue fever by controlling and preventing Aedesaegypti larva. The
intervention was conducted in Toongsawan-Sripanya community and compared to acontrol
community (Suwannachard community), located in Banleuam Sub-District, Muang District,
Udonthani Province. Education and training was provided twice per month between August
and December 2013. Aedesaegypti larva were surveyed in the communities once a month
during the same period. Baseline larva measurements in Toonsawan-Sripanya community
showed Housing Index (H.I.), Container Index (C.I.), and Breteau Index (B.I.) of 21.8%, 16.9%,
and 54.6, respectively. Baseline measurements in the control community were similar (H.I.,
C.I., B.I.=20.0%, 19.0%, 40.0).Pre-intervention incidence of dengue fever in Toonsawan-
Sripanya community and control community were21.89 and 16.4 per 100,000 population,
respectively.
The results showed that after providing education and training, time-averaged H.I.
(6.2 %), C.I. (1.4 %), andB.I. (6.9%) decreased several magnitudes in the experimental
community. Incidence (11.0 per 100,000 population) also decreased two-foldCompared to
the control community, a statistically significant differences in all indexes of Aedesaegypti
larva were observed (p-value < 0.001).
This study demonstratedthat this education and training intervention may be
effective in reducingaegyptilarva, which in turnreduces the incidence of dengue fever.
