How Dengue Fever Is Diagnosed: Tests and Procedures to Identify the Virus

Dengue Fever is a common mosquito-borne disease found in many tropical regions. It can cause mild to severe illness. In recent years, Dengue Fever cases have increased worldwide. Because of this, knowing the symptoms, causes, diagnosis, treatment, and prevention is important. Early action can help reduce the risk of serious problems.

What is Dengue Fever?

Dengue Fever is an illness caused by the dengue virus. The virus spreads through the bite of infected Aedes mosquitoes. These mosquitoes are active during the day. Dengue Fever can affect people of all ages. Most cases happen in warm, humid places. Although many people recover, some can develop severe forms of the disease.

Symptoms of Dengue Fever

Dengue symptoms usually appear 4 to 10 days after a mosquito bite. While some people have mild symptoms, others may feel very sick. Common symptoms include:

  • High fever (often sudden)
  • Severe headache
  • Pain behind the eyes
  • Muscle and joint pain
  • Nausea and vomiting
  • Skin rash (may appear a few days after fever starts)
  • Mild bleeding (such as nosebleeds or gum bleeding)
  • Sometimes, Dengue Fever can become severe. Warning signs of severe dengue include:

  • Severe stomach pain
  • Continuous vomiting
  • Bleeding from the nose or gums
  • Blood in vomit or stool
  • Extreme tiredness or restlessness
  • Causes and Transmission

    Dengue Fever is caused by four types of dengue viruses. These viruses spread mainly through the bite of Aedes aegypti and Aedes albopictus mosquitoes. These mosquitoes breed in standing water, like buckets, flower pots, or old tires. They bite during the day, especially in the early morning and late afternoon. Importantly, Dengue Fever does not spread directly from person to person. However, if a mosquito bites an infected person, it can carry the virus and infect others.

    Diagnosis

    Doctors diagnose Dengue Fever by checking symptoms and doing blood tests. If you have a high fever and live in or have traveled to a dengue-prone area, see a doctor. Blood tests can confirm the presence of the dengue virus or antibodies. Early diagnosis helps prevent complications. If you notice warning signs like severe pain or bleeding, seek medical help right away.

    Treatment Options

    There is no specific medicine to cure Dengue Fever. Most people recover with supportive care. Treatment focuses on relieving symptoms and preventing dehydration. Doctors may recommend:

  • Plenty of fluids to avoid dehydration
  • Rest to help the body recover
  • Pain relievers like acetaminophen (paracetamol)
  • However, avoid medicines like aspirin or ibuprofen. These can increase the risk of bleeding. In severe cases, hospital care may be needed. Doctors will monitor fluids and treat any complications.

    Prevention Tips

    Preventing Dengue Fever is possible with simple steps. Because mosquitoes spread the virus, reducing bites is key. Try these tips:

  • Use mosquito repellents on skin and clothing
  • Wear long-sleeved shirts and long pants
  • Sleep under mosquito nets, especially during the day
  • Keep windows and doors closed or use screens
  • Remove standing water from containers around your home
  • Change water in flower vases and pet bowls often
  • In some countries, a dengue vaccine is available for people in high-risk areas. Ask your doctor if this is right for you.

    When to See a Doctor

    If you have a high fever and live in or have visited a dengue-prone area, see a doctor. Seek medical help right away if you notice:

  • Severe stomach pain
  • Continuous vomiting
  • Bleeding from the nose or gums
  • Blood in vomit or stool
  • Extreme tiredness or confusion
  • Early treatment can prevent serious problems. Never ignore warning signs.

    Consult a healthcare professional for personalized advice and early diagnosis if you suspect Dengue Fever.
