symptoms of dengue fever: Dengue (pronounced DENgee) fever is a painful, debilitating mosquito-borne disease characterized by dengue virus closely related to anyone. These viruses are related to viruses that cause West Nile infection and yellow fever.
symptoms of dengue fever: An estimated 400 million dengue infections occur worldwide each year, with approximately 96 million resulting from the disease. Most cases occur in tropical regions of the world, with the greatest risk being:
Caribbean (excluding Cuba and Cayman Islands)
Central and South America (except Chile, Paraguay, and Argentina)
Most cases in the United States occur in people who contracted the infection while traveling abroad. But there is an increased risk for people living along the Texas – Mexico border and in other parts of the southern United States. In 2014, dengue fever outbreaks in Hawaii were identified in 2013, along with other outbreaks in Brownsville, Texas, and Key West, Fla.
Dengue fever is spread by a dengue virus-infected Aedes mosquito bite. The mosquito becomes infected when it bites a person with dengue virus in its blood. It cannot be spread directly from one person to another.
Symptoms of Dengue fever
Symptoms, which usually begin four to six days after infection and last up to 10 days, may include
Sudden high fever
Pain behind the eyes
Severe joint and muscle pain
Skin redness, which appears two to five days after the onset of fever
Mild bleeding (such as bleeding from the nose, bleeding from the gums, or easy sores)
Sometimes, the symptoms are mild and can be mistaken for flu or any other viral infection. Younger children and those who had never had an infection before had higher milk cases than older children and adults. However, serious problems can develop. These include dengue hemorrhagic fever, a rare complication of high fever, damage to lymph and blood vessels, bleeding from nose and gums, enlargement of liver and failure of the circulatory system. Symptoms can lead to massive bleeding, trauma, and death. This is called dengue shock syndrome (DSS).
People with a weakened immune system, as well as people with second or subsequent dengue infection, are considered at greater risk for developing dengue hemorrhagic fever.
Diagnosis of dengue fever
Doctors can diagnose dengue infection with blood tests to check for viruses or antibodies. If you become ill after a trip to a tropical region, tell your doctor. This will allow your doctor to evaluate the possibility that your symptoms were caused by a dengue infection.
Treatment of dengue fever
There is no specific medicine to treat dengue infection. If you think you may have dengue fever, you should use a pain reliever with acetaminophen and avoid medications with aspirin, which can worsen bleeding. You should rest, drink lots of fluids, and see your doctor. If you start feeling bad in the first 24 hours after the fever subsides, you should immediately go to the hospital for complications.
Prevent dengue fever
The best way to prevent the disease is to prevent bites by infected mosquitoes, especially if you are living or traveling in a tropical region. This includes protecting themselves and making efforts to keep mosquito populations down. In 2019, the FDA approved a vaccine called Dengvaxia to help prevent the disease in adolescents aged 9 to 16 who have already been infected with dengue. However, at present there is no vaccine to protect the general population from its contractions.
To protect yourself:
Use mosquito repellent indoors as well.
When going out, wear a long-sleeved shirt and long pants that rest in stockings.
When indoors, use air conditioning if available.
Make sure the window and door screens are safe and free of holes. If sleeping areas are not checked or air-conditioned, use a mosquito net.
If you have symptoms of dengue, talk to your doctor.
To reduce the mosquito population, get rid of the places where mosquitoes can breed. These include old tires, cans or flower pots that collect rain. Change water regularly in outdoor bird baths and pet water dishes.
If someone in your home gets dengue fever, be especially vigilant about efforts to protect yourself and other family members from mosquitoes. Mosquitoes that bite an infected family member can spread the infection to your home.
