Dengue is an infection caused by a virus. Dengue does not spread from person to person. It is common in warm, wet areas of the world. Outbreaks occur in the rainy season. It also known as breakbone fever that causes a severe flu-like illness.Dengue can vary from mild to severe; the more severe forms include dengue shock syndrome and dengue hemorrhagic fever (DHF). Patients who develop the more serious forms of dengue fever usually need to be hospitalized.
Dengue fever begins with a sudden high fever, often as high as 104 - 105 degrees Fahrenheit, 4 to 7 days after the infection. A flat, red rash may appear over most of the body 2 to 5 days after the fever starts. A second rash, which looks like the measles, appears later in the disease. Infected people may have increased skin sensitivity and are very uncomfortable. Other symptoms include fatigue, headache (especially behind the eyes), pain behind your eyes and muscle, bone and joint pain.
You might also experience nausea and vomiting, minor bleeding from your gums or nose and widespread rash. Most people recover within a week or so. In some cases, however, symptoms worsen and can become life-threatening. Blood vessels often become damaged and leaky, and the number of clot-forming cells in your bloodstream falls. This can cause bleeding from the nose and mouth, severe abdominal pain, persistent vomiting, bleeding under the skin, which may look like bruising and problems with your lungs, liver and heart. If severe, dengue fever can damage the lungs, liver or heart. Blood pressure can drop to dangerous levels, causing shock and, in some cases, death.
Dengue fever is caused by any one of four dengue viruses spread by mosquitoes that thrive in and near human lodgings. When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito. When the infected mosquito then bites another person, the virus enters that person's bloodstream. After you've recovered from dengue fever, you have immunity to the virus that infected you but not to the other three dengue fever viruses. 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.
Factors that put you at greater risk of developing dengue fever or a more severe form of the disease include living or traveling in tropical areas. Being in tropical and subtropical areas around the world especially in high-risk areas, such as Southeast Asia, Latin America and the Caribbean increases your risk of exposure to the virus that causes dengue fever.No specific treatment for dengue fever exists. Your doctor may recommend that you drink plenty of fluids to avoid dehydration from vomiting and high fever. If you have severe dengue fever, you may need supportive care in a hospital, blood pressure monitoring, and transfusion to replace blood loss.
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. It's particularly important to keep mosquitoes out at night.Second, seschedule outdoor activities. Avoid being outdoors at dawn, dusk and early evening, when more mosquitoes are out. Third, wear protective clothing. When you go into mosquito-infested areas, wear a long-sleeved shirt, long pants, socks and shoes. Fourth, use mosquito repellent. Permethrin can be applied to your clothing, shoes, camping gear and bed netting. You can also buy clothing made with permethrin already in it. Lastly, 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 as used automobile tires. Reduce the breeding habitat to lower mosquito populations.
