Dengue fever [classical dengue]

What is Dengue fever [classical dengue]?

Dengue fever, also known as classical dengue, is a viral illness spread by the bite of an infected Aedes mosquito. It is a leading cause of illness and death in tropical and subtropical areas around the world, with over 390 million people infected each year, according to the World Health Organization (WHO). Dengue fever can cause severe flu-like symptoms, including high fever, severe headache, and joint pain, and can potentially lead to life-threatening complications.

Causes and Risk Factors

Dengue fever is caused by a virus that is transmitted through the bite of an infected Aedes mosquito. The virus can be spread through the bite of an infected mosquito, and it can also be spread through blood transfusions, organ donations, and from mother to child during pregnancy. People who live in or travel to areas where dengue fever is common are at increased risk of infection. Other risk factors include having a weakened immune system, being under the age of 15, and having a history of previous dengue fever infection.

Signs and Symptoms

The symptoms of dengue fever typically begin within 3-14 days after the bite of an infected mosquito. Early signs of dengue fever include high fever, severe headache, joint pain, and muscle pain. As the illness progresses, patients may experience more severe symptoms, including severe abdominal pain, vomiting blood, and bleeding gums. In some cases, dengue fever can lead to life-threatening complications, such as hemorrhagic fever and shock syndrome.

How is Dengue fever [classical dengue] Diagnosed?

Dengue fever is typically diagnosed through a combination of physical examination, medical history, and laboratory tests. A healthcare provider may perform a physical examination to look for signs of infection, such as fever, rash, and joint pain. Laboratory tests, such as blood tests, may be ordered to confirm the diagnosis and to monitor the patient's condition. According to WHO guidelines, a diagnosis of dengue fever can be made based on a combination of clinical and laboratory criteria, including the presence of fever, headache, joint pain, and a positive laboratory test for dengue virus.

Treatment Options

The treatment of dengue fever typically involves supportive care, including rest, hydration, and pain management. In severe cases, hospitalization may be necessary to provide close monitoring and treatment. According to WHO guidelines, patients with dengue fever should receive supportive care, including oral or intravenous fluids, and should be closely monitored for signs of complications. In some cases, platelet transfusions may be necessary to manage bleeding complications. Medications, such as acetaminophen, may be prescribed to manage fever and pain.

Home Care and Self-Management

There are several steps that patients can take to manage their symptoms and prevent complications at home. These include getting plenty of rest, drinking plenty of fluids, and using over-the-counter pain relievers to manage fever and pain. Patients should also avoid taking aspirin or ibuprofen, as these medications can increase the risk of bleeding complications. According to WHO guidelines, patients with dengue fever should be encouraged to stay hydrated by drinking plenty of fluids, and should be monitored closely for signs of complications.

Prevention Strategies

The best way to prevent dengue fever is to avoid being bitten by infected mosquitoes. This can be done by using insect repellents, wearing protective clothing, and staying in air-conditioned or screened areas. According to WHO guidelines, communities can also take steps to prevent dengue fever by eliminating breeding sites for mosquitoes, such as standing water, and by using insecticides to control mosquito populations.

When to See a Doctor

If you are experiencing symptoms of dengue fever, such as high fever, severe headache, and joint pain, you should seek medical attention immediately. If you are experiencing severe symptoms, such as severe abdominal pain, vomiting blood, or bleeding gums, you should seek emergency medical attention. According to WHO guidelines, patients with dengue fever should be closely monitored for signs of complications, and should seek medical attention immediately if they experience any severe symptoms.
