What is the first sign of dengue fever?

The first signs of dengue fever typically appear within 3-14 days after a person is bitten by an infected mosquito. Some common early signs of dengue include:

  1. High fever: A sudden and high fever is often the first sign of dengue fever. The fever can be as high as 104-105°F and may last for 2-7 days.
  2. Headache: A severe headache, especially behind the eyes, is a common early symptom of dengue fever.
  3. Muscle and joint pain: Dengue fever can cause muscle and joint pain, which can be severe and long-lasting.
  4. Rash: A rash may appear on the skin, usually 2-5 days after the onset of fever.
  5. Nausea and vomiting: Nausea and vomiting are common symptoms of dengue fever.
  6. Loss of appetite: People with dengue fever may experience a loss of appetite, which can result in weight loss and fatigue.
  7. Fatigue: Fatigue and weakness are common symptoms of dengue fever, and can persist even after the fever subsides.

It is important to seek medical attention if you suspect that you have dengue fever, as the disease can progress to a more severe form called dengue hemorrhagic fever, which can be life-threatening. Early treatment can help to manage the symptoms and reduce the risk of complications.
