Abstract
BACKGROUND: At the verge of elimination of malaria in Bhutan, this study was
carried out to analyse the trend of malaria in the endemic districts of Bhutan
and to identify malaria clusters at the sub-districts. The findings would aid in
implementing the control activities. Poisson regression was performed to study
the trend of malaria incidences at district level from 1994 to 2008. Spatial
Empirical Bayesian smoothing was deployed to identify clusters of malaria at the
sub-district level from 2004 to 2008.
RESULTS: Trend of the overall districts and most of the endemic districts have
decreased except Pemagatshel, which has an increase in the trend. Spatial
cluster-outlier analysis showed that malaria clusters were mostly concentrated in
the central and eastern Bhutan in three districts of Dagana, Samdrup Jongkhar and
Sarpang. The disease clusters were reported throughout the year. Clusters
extended to the non-transmission areas in the eastern Bhutan.
CONCLUSIONS: There is significant decrease in the trend of malaria with the
elimination at the sight. The decrease in the trend can be attributed to the
success of the control and preventive measures. In order to realize the target of
elimination of malaria, the control measure needs to be prioritized in these
high-risk clusters of malaria.
