Dengue Fever: Symptoms, Causes, Treatments and Prevention

Dengue: Symptoms, Causes, Treatments

Dengue fever is transmitted by the bite of a mosquito named ‘Aedes’ infected with a dengue virus. The mosquito becomes infected when it bites a person with dengue virus in their blood. It can’t be spread directly from one person to another person.


Children and teens or many people may experience no signs or symptoms during a mild case of dengue fever. When symptoms do occur, they usually begin 4-7 days after you are bitten by an infected mosquito. Dengue fever causes a high fever with a temperature of 104 F degrees and at least two of the following symptoms:

Severe headaches

Sudden high fever

Pain behind the eyes


Nausea and Vomiting

Severe joint and muscle pain

Skin rash

Mild bleeding (such as nose bleed, bleeding gums, or easy bruising)

Swollen glands

Irritability or restlessness

Difficult or rapid breathing

 Blood in your urine, stools, or Vomit.


In some cases, symptoms become life-threatening. Blood vessels often become damaged and leaky sometimes. And the number of platelets in your bloodstream drops. This can cause a severe-dengue hemorrhagic fever, severe dengue or dengue shock syndrome. Signs and symptoms of dengue hemorrhagic fever or severe dengue can cause a life-threatening emergency.


Dengue fever is caused by any one of four types of dengue viruses spread by mosquitoes that thrive in and near humans. When a mosquito bites a person who has been infected with a dengue virus, the virus enters the mosquito. And then, when the infected mosquito then bites another person, the virus enters that person's bloodstream and infects the person this way.

After you've recovered from dengue fever, you have immunity to the type of virus that infected you — but not to the other three dengue fever virus types. The risk of developing severe dengue fever, also known as dengue hemorrhagic fever, actually increases if you're infected a second, third or fourth time.


If you are living or traveling in tropical areas where dengue fever is common, these tips may help reduce your risk of mosquito bites:

• Stay in air-conditioned or well-screened housing. The mosquitoes that carry the dengue viruses are most active from dawn to dusk and night.

• Wear protective clothing. When you go into mosquito-infested areas, wear a long-sleeved shirt, long pants, socks and shoes which will prevent.

• Use mosquito repellent. Permethrin can be applied to your clothing, shoes, camping gear and bed netting, etc. You can also buy clothing made with permethrin already in it. For your skin, use a repellent containing at least a 10 percent concentration of DEET.

• Reduce mosquito habitat. The mosquitoes that carry the dengue virus typically live in and around houses, breeding in standing water that can collect in such things. You can lower mosquito populations by eliminating habitats where they lay their eggs. At least once a week, empty and clean containers that hold standing water, such as planting containers, animal dishes, and flower vases, etc. Keep standing water containers covered.


There are no specific medications to treat dengue infection. If you think you may have dengue fever, you should use pain relievers with acetaminophen and avoid medicines with aspirin, which could worsen bleeding and cause problems. Also, painkillers, such as Tylenol or paracetamol which can help lower fever and ease the pain.

Preventing dehydration: A high fever and vomiting can dehydrate the body to some extent. And so, the person should drink clean water, ideally bottled rather than tap water. Rehydration drinks can also help replace fluids and minerals. One can include immunity-boosting drinks and hydration drinks. If you still don’t feel fine in the first 24 hours after your fever goes down, you should go to do a hospital visit immediately to be checked for complications. Hospitalization will allow the individual to be properly monitored, in case symptoms get worse.

More severe forms of fever may need:

intravenous (IV) fluid supplementation, or drip, if the person cannot take fluids orally.

blood transfusion, for patients with severe dehydration.
