Influence of Meteorological, Entomological and Environmental Parameters with Dengue Incidence in Kota Kinabalu, Sabah
Main Article Content
Abstract
Dengue fever represents a significant challenge to public health, affecting 3.9 billion individuals residing in 129 dengue endemic countries. Local dengue incidence is influence by environmental factors, including rainfall, temperature, humidity, and wind speed. This study aimed to determine the relationship between meteorological, entomological, and environmental parameters and dengue cases in Kota Kinabalu, Sabah. Materials and methods: An ecological study was conducted from 2016 to 2021 using the dengue database and meteorological data. Pearson's correlation coefficient was used to examine the correlation between the predictor variables and number of dengue cases in Kota Kinabalu. Results:A significant negative linear correlation (r=-0.28, p < 0.01) was observed between the weekly maximum temperature and weekly number of dengue cases. There was a significant negative linear correlation (r=-0.22, p < 0.01) between the weekly minimum temperature and weekly number of dengue cases. A strong positive correlation was observed between the weekly number of Aedes albopictus (r=0.65, p < 0.01) and the Aedes index (r=0.64, p < 0.01) and the weekly number of dengue cases. A significant positive linear correlation was found (r=0.39, p < 0.01) between the weekly number of vacant lots and weekly number of dengue cases. Conclusion: This clearly shows that temperature, entomological factors, and the presence of vacant lots play crucial roles in dengue occurrence in Kota Kinabalu, Sabah. Comprehensive dengue control strategies that consider environmental management, efficient vector control, and community engagement should not be overlooked.
