Dengue Hemorrhagic Fever (DHF): Symptoms and Prevention

Dengue Hemorrhagic Fever (DHF): Symptoms and Prevention

Dengue cases are on the rise in India, with reported deaths in several states. While dengue is a common illness, it is important to be aware of its severe form called Dengue Hemorrhagic Fever (DHF). DHF is a potentially life-threatening condition characterized by bleeding tendencies, a drop in platelet count, and plasma leakage that can lead to organ failure and shock if not treated promptly.

DHF is caused by infection with the dengue virus, which is primarily transmitted to humans through the bite of infected female Aedes mosquitoes, particularly the Aedes aegypti mosquito. After entering the body, the virus multiplies and spreads throughout the body over a period of 4 to 10 days.

DHF is more commonly associated with secondary dengue infections. This means that individuals who have been previously infected with one subtype of the dengue virus are at a higher risk of developing DHF if they are infected with a different subtype. It is important to note that there are four known serotypes of the dengue virus (DENV-1, DENV-2, DENV-3, and DENV-4).

Symptoms of DHF include high fever, intense headaches, severe joint and muscle pain, nosebleeds, gum bleeding, gastrointestinal bleeding, excessive abdominal pain and vomiting, restlessness, and irritability.

DHF is a medical emergency, and early diagnosis and proper treatment are crucial in preventing severe complications. It is essential to seek medical attention if you experience these symptoms, especially if you have previously been infected with dengue.

In order to prevent dengue and DHF, it is important to take measures to reduce mosquito breeding, such as getting rid of stagnant water around your home, using mosquito repellents, and wearing protective clothing.

Remember, being aware of the symptoms of DHF and taking preventive measures can help protect yourself and your loved ones from this potentially dangerous infection.
