Global Prevalence of Dengue Viral Infection, Its Pathogenesis Diagnostic and Preventive Approaches

Abstract

Dengue viral infection (DVI) is amongst a big Global health challenges. The clinical manifestations of disease ranges from subclinical Dengue fever (DF) to the complicated dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS). Reason behind this is the absence of specific tetravalent vaccine and the anti virals. The mortality rate with the infection might exceed upto 5%. Therefore, there is a dire need to emphasize the adoption of preventive strategies and to control the vector Aedesaegypti mosquito population. Moreover, the regular cross sectional, age stratified, serological surveys are the surveillance tools for monitoring the impact of Dengue prevention/ control and a better way to plan for potential epidemics.
