Dengue fever diagnosis
Dengue fever is diagnosed based on a combination of symptoms, physical examination, and laboratory tests. A healthcare provider will typically ask about your symptoms and recent travel history, and perform a physical examination to check for signs of dengue fever such as fever, rash, and bleeding.
To confirm the diagnosis, laboratory tests are needed, such as:
- Blood tests: A blood test can detect dengue virus or antibodies to the virus in the blood. The most common test is the RT-PCR (Reverse Transcriptase Polymerase Chain Reaction) test, which detects the genetic material of the virus in the blood.
- Serological tests: A serological test checks for antibodies in the blood that were produced in response to the dengue virus. These tests are used to confirm a diagnosis of dengue fever, but they can’t distinguish between a current infection and a past infection.
It’s important to note that early detection and treatment of dengue fever is crucial to prevent severe complications. If you suspect that you have dengue fever, seek medical attention immediately.

There is no specific medication to treat dengue fever. Treatment primarily involves relieving symptoms and supporting the body’s ability to fight the infection. This may include taking over-the-counter pain relievers, such as acetaminophen or ibuprofen, to reduce fever and pain, as well as getting plenty of rest and drinking fluids to prevent dehydration.
In severe cases, hospitalization may be necessary to provide supportive care, such as fluids and blood transfusions. It is also important to avoid medications that may increase the risk of bleeding, such as aspirin and non-steroidal anti-inflammatory drugs (NSAIDs).
In recent years, some studies have shown that administering the medication “Interferon alpha-2b” as a treatment for dengue fever can help lower the viral load in the blood and shorten the duration of fever, but it is not widely used and not FDA approved for dengue treatment.
It’s important to note that prevention is key when it comes to dengue fever, by avoiding mosquito bites and controlling the mosquito population.

How Dengue infect the human
Dengue virus is primarily transmitted to humans through the bites of infected Aedes mosquitoes. These mosquitoes typically bite during the day, and they are more active in the early morning and late afternoon. The virus can also be transmitted through blood transfusions or organ transplants from infected donors, as well as from mother to baby during childbirth. Once the virus enters the body, it infects cells in the liver and then spreads to the bloodstream, where it can infect other cells, including those in the lymph nodes, spleen, and bone marrow. This results in the symptoms of dengue fever, which can range from mild to severe.
The symptoms of dengue fever can range from mild to severe and typically appear within 3-14 days after infection. They include:
- High fever (over 102°F)
- Severe headache
- Pain behind the eyes
- Joint and muscle pain
- Fatigue
- Nausea and vomiting
- Skin rash, which usually appears 3-4 days after the onset of fever
- Mild bleeding (such as nosebleeds, bleeding gums, or easy bruising)
In severe cases, symptoms may also include:
- Severe abdominal pain
- Persistent vomiting
- Rapid breathing
- Bleeding from the gums or nose
- Fatigue
- Restlessness
- Cold, clammy skin
- Blood in the vomit or stools
It’s important to note that not everyone who is infected with the dengue virus will have symptoms, and in some cases, the symptoms may be so mild that they are mistaken for a cold or flu.
Prevention is key when it comes to dengue fever. The following measures can help reduce the risk of infection:
- Use mosquito repellent: Use an insect repellent containing DEET or picaridin, and reapply it according to the manufacturer’s instructions.
- Wear protective clothing: Wear long-sleeved shirts, long pants, and closed-toe shoes when you are in areas where mosquitoes are prevalent.
- Use screens or bed nets: Use screens on windows and doors, and sleep under a bed net if you are in an area where mosquitoes are prevalent.
- Eliminate standing water: Mosquitoes lay their eggs in standing water, so eliminate any standing water around your home, such as in bird baths, old tires, or flower pots.
- Use mosquito traps: Use mosquito traps, such as mosquito dunks or mosquito magnets, to control the mosquito population around your home.
- Avoid peak mosquito hours: Take extra precautions to avoid being bitten by mosquitoes during the early morning and late afternoon, when they are most active.
- Be aware of outbreak areas: Be aware of dengue fever outbreaks in the areas you are traveling to and take necessary precautions.
- Vaccination: Dengue vaccine is available in some countries, it’s not widely available. Consult your doctor regarding the availability of the vaccine and if it’s appropriate for you.
It’s important to note that taking these precautions can help reduce the risk of infection, but they are not foolproof. If you develop symptoms of dengue fever, seek medical attention immediately.
Dengue fever best antibiotics
Dengue fever is caused by a virus, not by bacteria, so antibiotics are not effective in treating the infection. Antibiotics are only used to treat bacterial infections and they have no effect on viral infections like dengue fever.
Treatment of dengue fever primarily involves relieving symptoms, such as fever and pain, and supporting the body’s ability to fight the infection. This may include taking over-the-counter pain relievers, such as acetaminophen or ibuprofen, to reduce fever and pain, as well as getting plenty of rest and drinking fluids to prevent dehydration.
In severe cases, hospitalization may be necessary to provide supportive care, such as fluids and blood transfusions. It is also important to avoid medications that may increase the risk of bleeding, such as aspirin and non-steroidal anti-inflammatory drugs (NSAIDs).
It’s important to note that there is no specific medication or treatment for dengue fever, and the best way to prevent and manage the disease is through avoiding mosquito bites and controlling the mosquito population, as well as seeking medical attention if you suspect you have dengue fever
Dengue fever prevention food
There is no specific food that can prevent dengue fever. However, maintaining a healthy diet and lifestyle may help boost your immune system and potentially reduce your risk of infection.
- Eating a balanced diet rich in fruits and vegetables can provide your body with essential vitamins and minerals that help boost your immune system.
- Consuming foods high in Vitamin C, such as oranges, kiwi, papaya, and berries, may help boost the immune system and reduce the risk of infection.
- Garlic and ginger are also believed to have antiviral properties and may help boost the immune system.
- Drinking enough water and staying hydrated is important to prevent dehydration.
- Incorporating probiotics in the diet can help to improve gut health and boost the immune system.
- Eating foods that help to boost the immune system is important, but it’s not a substitute for the preventive measures mentioned before: use mosquito repellent, wear protective clothing, eliminate standing water, use mosquito traps, avoid peak mosquito hours, be aware of outbreak areas, and consult your doctor about the availability of the vaccine.
It’s also important to note that dengue fever is caused by a virus that is transmitted by mosquitoes, not by food, so it’s important to take the necessary precautions to avoid mosquito bites.
Dengue fever best food
There is no specific food that is considered the “best” for people with dengue fever. However, maintaining a healthy and balanced diet can help support the body’s ability to fight the infection and manage symptoms.
- Eating a diet rich in fruits and vegetables can provide your body with essential vitamins and minerals that help boost your immune system.
- Consuming foods high in Vitamin C, such as oranges, kiwi, papaya, and berries, may help boost the immune system and reduce the risk of infection.
- Garlic and ginger are also believed to have antiviral properties and may help boost the immune system.
- Drinking enough water and staying hydrated is important to prevent dehydration, which is common in dengue fever.
- Incorporating probiotics in the diet can help to improve gut health and boost the immune system.
- Eating a balanced diet, with a variety of nutrient-dense foods, is important to provide the body with the necessary fuel it needs to fight the infection.
It’s important to note that when you have dengue fever, you need to maintain a balanced diet, but you don’t need to eat specific food to treat the disease. Dengue fever is caused by a virus that is transmitted by mosquitoes, not by food, so it’s important to take the necessary precautions to avoid mosquito bites and if you develop symptoms, seek medical attention immediately.
Dengue Fever Pattern in Adults
Dengue fever typically follows a specific pattern of symptoms. After a person is infected with the dengue virus, symptoms typically appear within 3-14 days. The following is a general pattern of symptoms:
- Phase 1 (Fever): The first symptom is usually a high fever (over 102°F) which can last for 2-7 days. Other symptoms that may occur during this phase include headache, muscle and joint pain, and fatigue.
- Phase 2 (Defervescence): The fever typically subsides and other symptoms may improve. However, some people may develop a rash and have a red or pink color of skin on the face and chest, this phase is called “break bone fever” due to the intense bone and joint pain.
- Phase 3 (Critical): In some cases, particularly in people who have had dengue fever before, the fever may return and the person may develop severe symptoms such as abdominal pain, vomiting, and bleeding. This is the most critical stage of the disease, known as Dengue Hemorrhagic Fever (DHF) and it can be fatal if not treated promptly.
It’s important to note that not everyone who is infected with the dengue virus will develop severe symptoms and not everyone will have the same symptoms. In some cases, the symptoms may be so mild that they are mistaken for a cold or flu. If you suspect that you have dengue fever, seek medical attention immediately.
Dengue Fever Pattern in Child
In children, the symptoms of dengue fever may be similar to those in adults, but they can also vary. Children may have a higher fever, and symptoms may be more severe than in adults. The following is a general pattern of symptoms in children:
- Phase 1 (Fever): The first symptom is usually a high fever (over 102°F) which can last for 2-7 days. Other symptoms that may occur during this phase include headache, muscle and joint pain, and fatigue. Children may also have a loss of appetite, abdominal pain and vomiting.
- Phase 2 (Defervescence): The fever typically subsides and other symptoms may improve. However, some children may develop a rash and have a red or pink color of skin on the face and chest.
- Phase 3 (Critical): In some cases, particularly in children who have had dengue fever before, the fever may return and the child may develop severe symptoms such as abdominal pain, vomiting, and bleeding. This is the most critical stage of the disease, known as Dengue Hemorrhagic Fever (DHF) and it can be fatal if not treated promptly.
It’s important to note that not every child who is infected with the dengue virus will develop severe symptoms, and not every child will have the same symptoms. If you suspect that your child has dengue fever, seek medical attention immediately.
It’s also important to take precautions to prevent dengue fever in children, such as using mosquito repellent, wearing protective clothing, and eliminating standing water.
