Study on the relationship between dengue hemorrhagic fever distribution and microclimate factors in Khanh Hoa province in an 11 year period (2004-2014)

Abstract

     Appearance and distribution of Dengue Hemorrhagic Fever (DHF) has been documented to be associated with microclimate factors. Studies on the distribution pattern and its connection with microclimate factors in Khanh Hoa province, which has been considered a DHF epidemic, would be helpful in preventing outbreaks in the region. Using statistics of DHF cases and a linear regression approach from  2004 to 2014, the study showed that the model of three independent variables: average temperature, average humidity and average rainfall varied, it explains 20% of DHF cases in the city of Nha Trang  and 30% in the city of Cam Ranh y. There existed a similarity in DHF distribuition between Nha Trang and Ninh Hoa; between Van Ninh and Dien Khanh; and between Cam Ranh and Cam Lam.
