Diagnosis
To diagnose dengue fever, your healthcare professional asks about your medical and travel history. Be sure to give details about trips abroad. Include the countries you visited and the dates. Also note any contact you may have had with mosquitoes.
Your healthcare professional may draw a sample of blood to be tested in a lab to see if you've been infected with one of the dengue viruses.
Treatment
There is no treatment for dengue fever, but there are ways to ease symptoms.
While recovering from dengue fever, rest and drink plenty of fluids. Call your healthcare professional right away if you get symptoms of severe dengue fever.
Also call your healthcare professional if you get any of the following symptoms. They could mean you've lost too much body fluid. This is a condition called dehydration.
- Less urinating.
- Few or no tears.
- Dry mouth or lips.
- Lack of energy or feeling confused.
- Cold or clammy hands and feet.
You can take acetaminophen (Tylenol, others) that you can get without a prescription to help lessen muscle pain and fever. But for dengue fever, don't take other pain relievers, including aspirin, ibuprofen (Advil, Motrin IB, others) and naproxen sodium (Aleve). These medicines can raise the risk of bleeding from dengue fever.
If you have severe dengue fever, you may need to go to a hospital for:
- Fluid and electrolyte replacement through a vein.
- Checking blood pressure and platelet count.
- Getting donor blood to replace blood loss.
