Dengue

Also called breakbone fever. Mosquito-borne viral disease with fever, headache, muscle and joint pain.Encyclopedia Entry for Dengue :Dengue - Break Bone fever- dengue fever - dengue virus (Flavivirus)Encyclopedia Entry for Dengue :Dengue fever. Dengue fever is caused by 1 of 4 different but related viruses. It is spread by the bite of mosquitoes, most commonly the mosquito Aedes aegypti , which is found in tropic and subtropic regions. This area includes parts of: Indonesian archipelago into northeastern Australia South and Central America Southeast Asia Sub-Saharan Africa Some parts of the Caribbean (including Puerto Rico and US Virgin Islands) Dengue fever is rare in the US mainland. Dengue fever should not be confused with dengue hemorrhagic fever, which is a separate disease caused by the same type of virus, but has much more severe symptoms.Dengue fever begins with a sudden high fever, often as high as 105 F (40.5 C), 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) Joint aches (often severe) Muscle aches (often severe) Nausea and vomiting Swollen lymph nodes Cough Sore throat Nasal stuffiness.Tests that may be done to diagnose this condition include: Antibody titer for dengue virus types Complete blood count ( CBC ) Polymerase chain reaction (PCR) test for dengue virus types Liver function tests.There is no specific treatment for dengue fever. Fluids are given if there are signs of dehydration. Acetaminophen (Tylenol) is used to treat a high fever. Avoid taking aspirin, ibuprofen (Advil, Motrin), and naproxen (Aleve). They may increase bleeding problems.The condition generally lasts a week or more. Although uncomfortable, dengue fever is not deadly. People with the condition should fully recover.Untreated, dengue fever may cause the following health problems: Febrile convulsions Severe dehydration.Call your health care provider if you have traveled in an area where dengue fever is known to occur and you have symptoms of the disease.Clothing, mosquito repellent, and netting can help reduce the risk for mosquito bites that can spread dengue fever and other infections. Limit outdoor activity during mosquito season, especially when they are most active, at dawn and dusk.O'nyong-nyong fever; Dengue-like disease; Breakbone fever.Mosquito, adult feeding on the skin Mosquito, adult feeding on the skin Dengue fever Dengue fever Mosquito, adult Mosquito, adult Mosquito egg raft Mosquito, egg raft Mosquito, larvae Mosquito, larvae Mosquito, pupa Mosquito, pupa Antibodies Antibodies.Centers for Disease Control and Prevention website.

It is spread through the bite of the Aedes aegypti mosquito. Recent years have seen dengue outbreaks all over Asia and Africa. Dengue fever can be mild to moderate, and occasionally severe, though it is rarely fatal. Mild cases, which usually affect infants and young children, involve a nonspecific febrile illness, while moderate cases, seen in older children and adults, display high fever, severe headaches, muscle and joint pains, and rash. Severe cases develop into dengue hemorrhagic fever, which involves high fever, hemorrhaging, and sometimes circulatory failure.Encyclopedia Entry for Dengue :Dengue virus. Flavivirus.
