what are the symptoms of dengue

Dengue is indeed a possibility considering your friend’s symptoms and recent travel to a tropical area. Dengue can begin with a sudden high fever, accompanied by severe headache and retro-orbital pain (pain behind the eyes). The ‘bone-breaking’ joint and muscle pain your friend described is actually quite characteristic of dengue and it’s often one of the most notable early symptoms. The rash you mentioned, which might look like red spots or blotches, often appears around the third to fifth day of fever and can be itchy or simply present as flat patches. The nausea, vomiting, and fatigue also fit within the classic presentation of dengue. In some cases, especially as the fever begins to diminish, warning signs can emerge indicating severe dengue: these include severe abdominal pain, persistent vomiting, rapid or difficult breathing, bleeding gums or nose, hematemesis (vomiting blood), or melena (black stool indicating gastrointestinal bleeding). Testing typically involves a blood test to check for dengue virus infection and assess platelet count since dengue can cause a drop in platelet levels, increasing bleeding risk. It’s important that your friend sees a healthcare provider promptly. They can confirm the diagnosis with appropriate tests and monitor for any complication signs that may require hospitalization, such as severe abdominal pain or signs of bleeding. While dengue is often self-limited, supportive care such as adequate hydration and fever control is crucial, and your friend should be cautious to avoid medications like aspirin or non-steroidal anti-inflammatory drugs that might increase bleeding risk. Encouraging medical evaluation is essential, especially if you notice any of the more severe or alarming symptoms, as timely intervention can significantly impact outcomes.
