Dengue fever is a viral infection caused by the dengue virus that is transmitted through the bite of the infected Aedes mosquito.
Symptoms of dengue fever include the below:
• sudden onset of fever that lasts 3 to 7 seven days
• a severe headache especially in the back of the eye
• pain experienced in the muscles and joints, especially in knees, ankles, elbows
You may also suffer from an unpleasant taste in the mouth, loss of appetite which is often accompanied by abdominal pain, vomiting and diarrhea.
Other indications may be
• rashes on the arms and the legs,
• severe itchiness leading to peeling of skin and hair loss as well,
• heavy menstrual periods in women, minor bleeding from the nose or the gums
• flushing of the skin on the face and the neck
