Abstract
There are over 60 countries where dengue fever is endemic, and 2.5 billion
people could get sick from it. An RNA virus belonging to the Flaviviridae family that
causes acute viral disease dengue is transmitted by Aedes mosquitoes. The presenting
signs may be asymptomatic fever with severe implications such as hemorrhagic fever
and shock. The most common symptoms are acute-onset high fever, cutaneous rash,
hemorrhagic episodes, myalgia and circulatory shock. Although oral symptoms are
seldom the primary presenting sign of dengue infection, they may occur in certain
cases. Early and precise diagnosis is necessary for lowering mortality. Dengue virus
infections are typically self-limiting, but in tropical and subtropical countries, dengue
infection has become a public health threat. A detailed explanation of dengue virus
infections, clinical symptoms, diagnostic techniques, and preventative measures are all
included in this book chapter.
