Dengue Fever
Dengue is a febrile viral illness transmitted through mosquitos and is transmitted by blood, organ, and tissue (bone marrow) of an infected person, or from mother to infant if mother infected close to time of birth, and through breast milk.
Occurs in subtropic and tropic areas in more than 100 countries in the world. It occurs in similar areas as malaria, but tends to occur in urban and residential areas more than malaria.
Up to 5% of infected people have life threatening disease. 75% of people infected may not have symptoms. The fever lasts 2-7 days. Other symptoms include severe headache, pain behind the eyes, muscle, joint and bone pain, rash, bruising, nose bleeds, and bleeding gums. Warning signs of worsening disease include nausea, severe abdominal pain, difficulty breathing, and signs of shock.
There is no specific antiviral mediations to treat Dengue Fever. Aim is at supportive treatment with fluids, rest, avoiding aspirin, and NSAIDS. Fever is controlled with tylenol and tepid baths. Those with fever should be monitored closely and may need intensive care. Infected people should avoid mosquito bites to prevent further transmission to others.
There is no vaccine for Dengue Fever. Recent studies showed experimental vaccine was not to be used for individuals who have not had Dengue Fever before.
Prevention is aimed at avoiding mosquito bites. Sleep were there are well screened windows, or air conditioning. Often found
in dark, cool places. Wear clothing that covers your arms and legs during early morning and late afternoon when risk of biting is highest.
Use insect repellents with DEET, pricadin, or permethrin.
Empty and clean areas that have standing water.
