Dengue fever

What to know about Dengue fever


Dengue fever’s symptoms are similar to those of other illnesses, making diagnosis challenging. These include chikungunya, Zika virus, malaria, and typhoid.

You might expect questions regarding both your health and your recent travels from your doctor. Please include specifics about your overseas travels, such as the countries you visited, the dates of your travels, and any mosquito encounters you may have had.

There is also the possibility that your doctor may take a blood sample to check for dengue virus infection.

Dengue’s mild symptoms are shared by a wide variety of different diseases that manifest themselves with a high body temperature, joint discomfort, and/or a rash.

Dengue is characterized by a high temperature accompanied by any of the following symptoms:

  • Feeling sick to one’s stomach and throwing up
  • Rash
  • Discomforts and pains (eye pain, typically behind the eyes, muscle, joint, or bone pain)
  • An indicator of danger

The duration of dengue fever is usually between two and seven days. Within a week, most individuals will feel better.


This article will discuss four viruses.

Dengue fever may be spread through a Reliable Source. All of these diseases are spread by the Aedes aegypti mosquito or, less often, the Aedes albopictus mosquito.

These mosquitoes are found in both tropical and subtropical regions, including certain locations of the United States (Trusted Source). Infection rates have risen during the last several decades, particularly in densely populated cities.

When a mosquito infected with the virus bites a person, the infection is transmitted. Another mosquito will get infected with the disease if it bites a person who already has it. After then, the mosquito will infect the next person it bites.

Multiple episodes of dengue fever are possible. The individual will develop immunity to the causative virus but will continue to be susceptible to the other three.


Dengue fever currently has no cure.

Stay hydrated while you work to overcome dengue fever. If you experience any of the following symptoms of dehydration, you should seek medical attention immediately:

  • Decreased need to go to the bathroom
  • With little to no crying
  • The sensation of dryness in the mouth or lips.
  • Inertia or haziness
  • Painful, numbing, or icy fingers or toes

Muscle discomfort and fever may be alleviated with the aid of acetaminophen, which is available without a prescription as Tylenol and other brands. In contrast, aspirin, ibuprofen (Advil, Motrin IB, and others), and naproxen sodium are not recommended for use by those with dengue fever (Aleve). The risk of bleeding problems from dengue fever may be increased by the use of certain pain medications.

Severe cases of dengue fever may require:

  • Hospital-based palliative care
  • Sustaining fluid and electrolyte balance using intravenous (IV) therapy
  • Checking the blood pressure
  • To replenish lost blood, a transfusion is performed.


The virus that causes dengue fever is transmitted through mosquito bites. Symptoms are seldom experienced by the general population. If they do, however, the effects are often minor. Dengue fever has the potential to be fatal in certain people.

In addition to a rash, fever, and other aches and pains are also common. Extreme cases may cause the patient to vomit repeatedly or to bleed from the gums or nostrils. When dengue fever becomes severe, it is time to see a doctor.
