12. The relationship between climate factors and dengue fever in Vietnam, during the period of 1997 to 2017

Abstract

Dengue fever is an acute infectious disease caused by Dengue virus (DEN). It is horizontally spread with mosquito (genus Aedes) acting as the disease vector. There are four types of Dengue virus found in Vietnam: DEN - 1 and DEN - 2 are predominant; DEN - 3 appeared in late 1990 and caused an outbreak in 1998; while DEN - 4 was discovered between 1999 and 2003. This paper uses Geographic Information System (GIS) method to develop spatial distribution maps of some climate factors and Dengue fever. Hemorrhagic fever has been linked to changes in weather and climate. Research results in the period 1997 - 2017 show that the average annual temperature, rainfall and total evaporation are directly proportional to DEN incidence ratio. 1oC rising in temperaturecorresponds to 30/10 thousand people having DEN. Increase rainfall of 100 mm results in 2 people having DEN in total of ten thousand people. Rising 100 mm of total evaporation leads to 26/10 thousand people having DEN. The dengue fever usually appears from July, the peak of outbreaks is from August to December
