I am diagnosed with dengue: what should I know?

Dengue is a mosquito-borne viral infection. Fever, headache, muscle aches, joint pain, chills, nausea, and easy bruising can occur, but symptoms vary. Feeling better does not always mean monitoring can stop, because warning signs may appear as the fever settles. Your clinician can explain the expected course, review your examination and any tests, and tell you when reassessment is needed. Read more about dengue fever and the symptoms you are experiencing.

Rest and take frequent fluids as advised; ask about an oral rehydration drink if eating or drinking is difficult. Use only medicines your clinician recommends, and check before taking pain relievers or anti-inflammatory medicines because some may increase bleeding risk in dengue. Avoid mosquito bites while you are ill by using nets, screens, and suitable repellent, which helps reduce spread to others. Keep your follow-up appointment and record temperature, fluid intake, urination, vomiting, bleeding, and changes in alertness.

Seek urgent medical care for severe abdominal pain, repeated vomiting, bleeding from the gums or nose, blood in vomit or stool, unusual sleepiness or restlessness, trouble breathing, fainting, cold or clammy skin, or inability to drink or pass urine. Do not wait for the next appointment if a warning sign develops. Contact your care team promptly if fever returns or symptoms worsen.

Ask which fluids and medicines are suitable, how often you should be reviewed, which warning signs matter most for you, and when blood tests are needed. Also ask how to protect household members from mosquito bites and what to do if you cannot keep fluids down.
