Resumo de Dengue Fever Fact

Dengue [DEN-ghee] is a flu-like viral disease spread by the bite of infected mosquitoes. Dengue hemorrhagic fever is a severe, often fatal, complication of dengue. Dengue occurs in most tropical areas of the world. Most U.S. cases occur in travelers returning from abroad, but the dengue risk is increasing for persons living along the Texas-Mexico border and in other parts of the southern United States. There is no specific treatment for dengue. Prevention centers on avoiding mosquito bites in areas where dengue occurs or might occur and eliminating breeding sites. Dengue fever is an infectious disease carried by mosquitoes and caused by any of four related dengue viruses. This disease used to be called ?break-bone? fever because it sometimes causes severe joint and muscle pain that feels like bones are breaking, hence the name. Dengue is a tropical and subtropical disease carried by Aedes mosquitoes, especially A. aegypti. According to the World Health Organization, 2.5 billion people around the world are at risk from dengue. Currently, more than 100 countries have experienced dengue. Each year there are tens of millions of cases, and as many 95% are children. You can get dengue virus infections from the bite of an infected Aedes mosquito. Mosquitoes become infected when they bite infected humans, and later transmit infection to other people they bite. Two main species of mosquito, Aedes aegypti and Aedes albopictus, have been responsible for all cases of dengue transmitted in this country. Dengue is not contagious from person to person. Symptoms of typical uncomplicated (classic) dengue usually start with fever within 5 to 6 days after an infected mosquito has bitten you and include:High fever, up to 105 degrees Fahrenheit Severe headache Retro-orbital (behind the eye) pain Severe joint and muscle pain Nausea and vomiting Rash There is no specific treatment for classic dengue fever, and like most people you will recover completely within 2 weeks. To help with recovery, health care experts recommend:Getting plenty of bed rest Drinking lots of fluids Taking medicine to reduce fever The best way to prevent dengue fever is to take special precautions to avoid contact with mosquitoes. Several dengue vaccines are being developed, but none is likely to be licensed by the Food and Drug Administration in the next few years. When outdoors in an area where dengue fever has been found Use a mosquito repellant containing DEET, picaridin, or oil of lemon eucalyptus Dress in protective clothing-long-sleeved shirts, long pants, socks, and shoes Because Aedes mosquitoes usually bite during the day, be sure to use precautions especially during early morning hours before daybreak and in the late afternoon before dark. Dengue hemorrhagic fever is also on the rise. Persons who have been infected with one or more forms of dengue virus are at greater risk for the more severe disease. With the increase in all types of virus, the occurrence of dengue hemorrhagic fever becomes more likely.
