Dengue is a disease caused due to the virus transmitted by mosquitoes. Dengue infection can be observed if the ‘dengue triad’ i.e. fever, rash, and headache can be spotted. The Dengue fever is characterized in two phases namely acute and convalescent. The initial muscle pain and fever symptoms fall in acute phase which lasts for 4-5 days. Once the fever subsides the convalescent phase begins and can last upto 7 days. Dengue Virus (DENV) level is higher in blood during first phase and, therefore, real time PCR test is carried out to detect this virus so that it can be treated in its initial stages itself.
