Microclimatic effect on dengue fever outbreak / Nor Syazwani Jamaluddin

Dengue fever has escalates around the world in recent decades and the number of cases
rise up year by year. Vegetation and temperature could be the possible factors of the
dengue transmission due to microclimatic effects. Remote Sensing technique with the
indices technique is found capable to monitor the dengue due to microclimatic effects.
Another factor that may contribute to the growth of dengue fever outbreaks is
urbanization. Urbanization provided the ideal ecology for these mosquitoes referring to
the increased density of populations as people flock to cities in search of employment.
Thus, the aim of this study is to determine microclimatic effect on dengue fever outbreak
based on the relationship between vegetation (NDVI), Land Surface Temperature (LST)
of Remote Sensing satellite image and dengue at Kedah and Penang from year 2010 to
2014 during North-East Monsoon. The objectives are to identify vegetation changes
based on NDVI, to quantify temperature based on LST and to determine relationship
between NDVI, LST and dengue fever outbreak. The strong relationship found
between number of dengue eases and climatic factors which are NDVI and LST. It can he
concluded that climatic conditions have a strong influence on dengue outbreak.
