Frequent dengue outbreaks in South Asian countries: analysis of associated risk factors and possible preventive measures

Abstract

Dengue, a mosquito borne viral disease has now become one of the most alarming threats of the world. Each year approximately 400 million people are affected by dengue globally. Among them 100 million people get sick by the dengue virus along with 40,000 deaths. Asia pacific region is the most favorable place for dengue borne mosquitoes to raise their descendants due to the hot and humid environment and heavy rainfall. The objective of my project is to find out the reasons of high dengue viral fever spreading in South Asian regions, the associated risk factor that is cause by dengue and the possible preventive method to stay safe from dengue. The data and information of the project were taken, reviewed and analyzed from different verified data source which includes Scopus, PubMed, ScienceDirect and Google Scholar. Throughout my project I find out few points that trigger the high dengue cases in south east Asia. The large population, unplanned urbanization, low per capita income, low quality of life, poor economic structure makes it more difficult to control the outbreak of dengue in the Asia pacific region. Dengue severity mainly lasts for two to three months. So, if this time frame can be monitored effectively, the severity should be lessened to a greater extent. Severe dengue requires immediate supportive care to save the affected patient's life. Doctor counseling is mandatory for them to get rid of fetal severity. Few vaccines showing promising result in market along with few upcoming vaccines that are in clinical trial phase.
