Dengue fever Symptoms, Causes, Treatment and More

Dengue fever is a viral illness transmitted by the Aedes mosquito species, predominantly Aedes aegypti. This mosquito-borne disease found predominantly in tropical and sub-tropical climates worldwide, often in urban and semi-urban areas. The symptoms range from mild fever to severe complications, such as dengue hemorrhagic fever. This document provides an overview of the causes, symptoms, and treatment options for dengue fever.

What is Dengue fever?

Dengue fever a viral infection caused by one of four closely related viruses, known as serotypes: DEN-1, DEN-2, DEN-3, and DEN-4. The virus is primarily spread through the bite of infected Aedes mosquitoes, which become carriers of the virus after biting an infected human or primate. Dengue fever cannot spread directly from person to person, but rather through the bite of an infected mosquito.

The symptoms of dengue fever can vary from person to person and may appear 4-7 days after being bitten by an infected mosquito. Some common symptoms include:

In certain cases, dengue fever has the potential to give rise to more severe symptoms, including dengue hemorrhagic fever or dengue shock syndrome. These complications can pose a life-threatening risk and necessitate prompt medical intervention.


Dengue fever caused by one of the four dengue viruses, which transmitted through the bite of infected Aedes mosquitoes. These mosquitoes can become infected with the virus after biting a person who is already infected. The virus then multiplies in the mosquito’s body and can pass on to other humans when it bites again.


Currently, there is no specific medication or treatment for dengue fever. Treatment focuses on relieving symptoms and preventing dehydration. If you are experiencing dengue fever symptoms, it is important to seek medical attention immediately. Your doctor may recommend the following:

  • Rest and plenty of fluids to prevent dehydration
  • Medications such as acetaminophen (Tylenol) to reduce fever and pain
  • Close monitoring of symptoms and fluid intake
  • Hospitalization for severe cases or complications


Treatment for dengue fever primarily focuses on managing the symptoms of pain. Acetaminophen (paracetamol) commonly used for pain control, while nonsteroidal anti-inflammatory drugs like ibuprofen and aspirin avoid due to their potential to increase the risk of bleeding.

In terms of preventive measures, there is a vaccine called Dengvaxia available for individuals who have previously experienced dengue fever and reside in areas where the disease is prevalent.

For individuals with severe dengue fever, hospitalization is typically require in the majority of cases.


The best way to prevent dengue fever is to avoid being bitten by infected mosquitoes. You can do this by taking the following precautions:

  • Use insect repellent containing DEET when spending time outdoors, especially in tropical and sub-tropical areas
  • Wear long-sleeved shirts and pants when possible
  • Use mosquito nets while sleeping in areas where dengue fever is prevalent
  • Eliminate standing water sources around your home, as these are breeding grounds for mosquitoes

It is also important to stay informed about any outbreaks or cases of dengue fever in your area and take necessary precautions. If you have previously had dengue fever, it is important to take extra precautions to avoid getting re-infected with a different serotype, as this can lead to more severe symptoms.

Frequently Asked Questions

Is dengue fever contagious?

No, dengue fever is not directly contagious from person to person. It can only transmitted through the bite of an infected mosquito.

Can you get dengue fever more than once?

Yes, it is possible to get dengue fever multiple times. However, developing immunity to one serotype does not protect against the other three serotypes, so it is still possible to get dengue fever again with a different serotype.

Is there a cure for dengue fever?

Currently, there is no specific cure for dengue fever. Treatment focuses on managing symptoms and preventing complications.


Dengue fever is a viral illness that can range from mild to severe, with potentially life-threatening complications. It is spread by infected Aedes mosquitoes and there is currently no specific medication or treatment for the disease. The best way to prevent dengue fever is to avoid being bitten by infected mosquitoes and stay informed about any outbreaks in your area. If you experience symptoms of dengue fever, seek medical attention immediately. So, it is important to take necessary precautions and stay informed about the disease to protect yourself and others from this potentially dangerous illness. Stay safe!
