What is the first phase of dengue characterized by mild hemorrhagic manifestations?

The first phase of dengue characterized by mild hemorrhagic manifestations is the febrile phase. During this initial phase, which typically lasts for about two to seven days, patients experience high fever, severe headaches, pain behind the eyes, joint and muscle pain, and skin rashes. Mild hemorrhagic signs may begin to manifest, such as petechiae (small red or purple spots on the body) and nosebleeds, which are notable features of this phase.

It is important to recognize that the febrile phase sets the stage for the disease's progression, which can lead to more severe forms of the illness if not monitored effectively. Following this, individuals may transition into critical or acute phases, where more severe symptoms can occur. Thus, understanding the febrile phase and its manifestations is crucial for early identification and management of dengue fever.
