Dengue hemorrhagic fever

Dengue Hemorrhagic Fever (DHF) is a severe, potentially deadly infection spread by certain species of mosquitoes (primarily Aedes aegypti).

Overview

DHF is caused by infection with the same viruses that cause Dengue fever. Dengue is common in more than 100 countries around the world. Forty percent of the world's population, about 2.5 billion people, live in areas where there is a risk of dengue transmission. Dengue is often a leading cause of illness in areas with risk.

Symptoms

The symptoms of DHF, which are similar to those of dengue fever, include headache, fever, skin rash, and severe joint and muscle pain. These symptoms begin four to seven days after the bite of an infected mosquito. The skin rash that occurs is characteristic of DHF because it appears first on the lower limbs and the chest; in some patients, it spreads to cover most of the body. There may also be severe stomach pain, and vomiting.

Diagnosis

DHF is diagnosed by a blood test. The test can show the presence of the virus or antibodies made in response to the virus. It is important to see a healthcare provider if you have recently traveled to an area where dengue is common and you have symptoms of dengue.

Treatment

There is no specific treatment for DHF. Treatment is aimed at relieving the symptoms. This may include rest, fluids to prevent dehydration, and medication to reduce fever and pain. Hospitalization may be necessary.

Prevention

Prevention of DHF involves avoiding mosquito bites in areas where dengue is common. This can involve wearing protective clothing, using mosquito repellent, and staying in air-conditioned or well-screened rooms.
