Dengue - Symptom, Treatment And Causes

What is Dengue?

Dengue fever is a debilitating and painful viral disease spread by mosquitoes. There are four dengue viruses which may transmit the disease. Most cases of dengue are found in tropical parts or countries in the world. An Aedes mosquito that has been infected by a dengue virus can further transmit it. The mosquito gets infected after biting another person infected with the dengue virus. Direct transmission from one person to another doesn’t take place.

Diagnosis and Treatment :


Blood tests for checking traces of the virus or the antibodies produced in response to it are available. Consult a doctor if you get unwell after visiting a tropical country.


Dengue doesn’t have any specific medicine for treating it. If you suspect dengue fever, then take pain killers having acetaminophen. Don’t take aspirin, as it may make the bleeding worse. Rest along with adequate fluid intake is of utmost importance. Consult your doctor if you don’t feel better even after the fever reduces.


No vaccine has been invented so far for preventing dengue. The best prevention for dengue fever is to avoid getting bitten by mosquitoes, especially when you’re travelling to or living in the tropics. Protection from mosquitoes and attempts to lower the mosquito populace can help in prevention.

Here are a few tips for protecting yourself:

  • Buy and use an effective mosquito repellent, even when you’re indoors.
  • When you’re outdoors, minimize skin exposure. Wear shirts with long sleeves and tuck your pants into socks.
  • If possible, then increase the use of air conditioning.
  • Avoid residential areas that are densely populated.
  • Sleep inside a mosquito net.
  • Ensure that the windows don’t have any holes and the doors and partitions are properly sealed when shut.
  • If you show any of the symptoms for dengue, consult your doctor.

In bringing the mosquito population down, remove or block places which might be breeding grounds for mosquitoes. These may be places where rain water accumulates such as cans, old tires and flower pots. Keep changing the water in coolers and bird baths. If a member of your family gets dengue fever, take extra measures to protect others in the house including yourself from mosquito bites. The infected person in the house may get bitten and that mosquito might transmit the virus to others in the house.

Treatable by medical professional Require medical diagnosis Lab test not required Short-term: resolves within days to weeks Non communicable
High fever that has a sudden onset Severe muscular and joint pain Fever followed by appearance of a skin rash Mild bleeding from the nose and gums

Dengue - How To Prevent Yourself?

General Physician, Delhi
Dengue - How To Prevent Yourself?

Dengue is caused from the bite of the ‘Aedes Aegypti’ mosquito. This mosquito has been known to breed and survive in tropical and subtropical regions. A waterborne disease, it causes extreme discomfort and pain, even death is a possibility. Statistics suggest that each year, the number of people afflicted with dengue is around 390 million. Out of this huge number, 96 million tend to develop severe illnesses wherein hospitalization becomes mandatory.


  1. It is primarily caused due to the bite of the ‘Aedes aegypti’ mosquito.

  2. A mosquito becomes infected with dengue if it bites an already infected person. The disease can be transmitted to any healthy person that this infected mosquito bites next.

  3. Living near a stagnant water body or an open drain makes you the most vulnerable to this disease. Letting water accumulate in open containers or spaces over a period of time makes it the perfect breeding ground for all types of mosquitoes.


On being infected, the symptoms generally last for around 10 days. Some of the common symptoms are:

  1. Excruciating pain behind the eyes

  2. Severe headache

  3. Sudden high fever with chills

  4. Vomiting

  5. Fatigue

  6. Skin rash which generally appears two to five days after you get infected

  7. Nose bleeding, easy bruising and bleeding gums

  8. Severe muscle and joint pain

It should be noted that these symptoms can be easily mistaken for high fever or any other viral infection. Therefore, getting tested as soon as these symptoms start appearing is very important.

If the dengue is left untreated or not treated on time, it can result in dengue haemorrhagic fever. This condition causes nose bleeding (due to damage to the blood vessels), high fever and failure of the circulatory system as well as the enlargement of liver.

Ways to prevent dengue include

  1. Avoid storing water in containers

  2. Wear clothes that cover your whole body, if possible

  3. Maintain hygiene and clean your immediate surrounding frequently

  4. Use mosquito repellent

  5. Use a mosquito net around your bed

In worst case scenarios, death is a possibility as a result of dengue haemorrhagic fever or dengue shock. Many countries consider dengue to be an epidemic. You need to be on complete bed rest while drinking adequate amounts of fluids if you need to recuperate from dengue.


There is no specific antiviral medication that is available for the treatment of dengue. In general, Acetaminophen (paracetamol) is usually recommended for treating fever and pain associated with dengue. Medications such as Aspirin, other salicylates, and nonsteroidal anti-inflammatory drugs (NSAIDs) must be avoided.

Dengue Fever - 6 Ways You Can Protect Yourself!

Dengue fever is a disease caused by mosquitoes which mostly occurs in tropical climates. Dengue hemorrhagic fever is a type of dengue fever that may lead to decrease in blood pressure and severe bleeding. Dengue may lead to death if the symptoms of this disease are not treated at the right time. The symptoms of this disease are high fever, muscle ache, pain in the eyes, pain in the abdomen and nausea. It may also lead to respiratory problems such as breathing difficulties. Presence of blood in the stool and blood spots around the skin are some other symptoms of dengue.

The symptoms of this disease start after 5 - 9 days after being bitten by the mosquito. The disease usually lasts about 7-8 days. In case the symptoms worsen, the disease may become life threatening. 

The various methods you can employ to protect yourself from dengue are:

  1. Maintain cleanliness around your surroundings: Make sure you keep your surroundings clean so that mosquito infestations do not occur. Keep your surroundings clean and dry as mosquitoes thrive in moist and humid surroundings.
  2. Mosquito repellents: Spray mosquito repellents to keep your home free from mosquitoes. Spray them keeping the room locked to make it more effective. There are multiple types of repellents available such as liquid or gas repellents.
  3. Clothes: You should preferably wear full sleeved clothes so that your skin is not exposed. It provides additional protection from mosquito bites.
  4. Mosquito nets: Use mosquito nets to protect yourself from mosquitoes when you go to sleep at night. They also provide protection from other insects that may cause infections. 
  5. Don't store waste: Don't store your waste products for long durations as they may turn into a breeding ground for mosquitoes. Clean it regularly and make sure to keep the area dry.
  6. Using natural remedies: You may use natural remedies such as burning camphor as it repels mosquitoes. Take camphor and burn it for 20 minutes in a closed room to get rid of the mosquitoes.

Dengue is mostly widespread in tropical regions such as India, South-East Asia, Central and South America, South China, Taiwan and Africa among others. There are 4 distinct types of dengue virus and the symptoms can appear within 3-14 days of the bite.


If you have a weak immune system or have suffered from this disease previously, you could be at increased risks of it. Common symptoms include:

Dengue is not a contagious disease. It can only spread through the bite of an infected Aedes mosquito.

How it can be treated?
1. If you suspect dengue, you must rush to the doctors and get the diagnosis done. Timely start of therapy is essential to tackle the Dengue Shock Syndrome and internal bleeding.
2. Complete bed rest and sufficient intake of fluids is advised
3. Pain relievers can be administered along with Acetaminophen but Aspirin should be strictly avoided
4. If you are unable to eat normally, intravenous fluids will be administered to prevent dehydration
5. A platelet transfusion may also be considered

Dengue - 5 Ways You Can Prevent Yourself Against It!

Dengue - 5 Ways You Can Prevent Yourself Against It!

The monsoons cool the air down but also provides an ideal breeding ground for mosquitoes. A mosquito bite is universally abhorred. A sting that turns into dengue is even more disliked. Dengue is a mosquito borne disease that causes high fever, rashes and pain in joints and muscles. Since there is no vaccine that can completely eradicate dengue, it becomes important to take preventive measures to reduce mosquitoes and keep the disease at bay.

Here are a few tips that can reduce your risk of being bitten by mosquitoes:

  1. Do not allow water to accumulate: Mosquitoes breed in standing water. To prevent this do not allow rainwater to collect in pots or stagnate in your garden. Ensure that your water tanks are kept covered always. Keep buckets turned over when not in use. Coolers are generally ineffective in the monsoons so empty them out and keep the trays dry. It is also a good idea to empty and dry swimming pools and ornamental fountains during the monsoons.
  2. Use mosquito repellant: Dengue mosquitoes typically bite a person during the day. Hence, make it a habit to put on a mosquito repellant along with your sunscreen every time you step out. Mosquito repellants should be used on all the exposed areas of your skin including your ears. Using a mosquito net around your bed at night is the best way to ensure safety against mosquitoes. You could also attach mosquito repellant patches on your infant's clothes.
  3. Do not allow mosquitoes indoors: Install mesh shutters on your doors and windows. This will allow air in but will keep mosquitoes out. Take a close look at your doors and windows for holes through which mosquitoes could come in. Also look at their joints and edges to ensure that there are no gaps. Burning camphor and lavender or tea tree aromatics can also help keep mosquitoes away.
  4. Grow mosquito repellant plants: Citronella and tulsi are two plants that are well known for their mosquito repelling properties. Grow these plants near your window and the entrance of your house to naturally repel mosquitoes.
  5. Avoid outdoor activities at dawn and dusk: Sunrise and sunset are when mosquitoes are most active. Hence avoid being outdoors at this time. If you must be out, wear protective clothes that minimize the amount of skin exposed. Wearing light colours instead of dark colours can also help as mosquitoes are attracted to dark colours.

Dengue Fever
My name is Dr Tarun Jhamb and I m an MD Medince. I am practising for last fifteen years. I am connected to Lybrate. I m also practising at Columbia Asia Hospital and we will discuss the health topic one of which is Dengue Fever. We know for the next three months, there is a possibility of Dengue Fever in the rainy season. Dengue is a mosquito borne viral fever and it just spreads from the bite of the mosquito and spreads person to person. Most of the times it is self-treatable and it s a preventable disease but there are a few cases which have gone into complications which are known as Dengue Shock Syndrome or Dengue haemorrhaging Fever.

Common symptoms of the Dengue Fever is the high-grade fever, 104- 105 temperature with body ache, joint pain, muscle pain, rashes all over the body, and severe weakness. A person becomes very dilapidated within one or two days and feels very uncomfortable and he becomes sick. It is a treatable disease. Lots of liquids and electrolytes are required.

What are the dos and don ts for this disease?

Do is, we have to take care of not getting stagnant water in coolers or in and around the home. We should take care of using the mosquito repellent, material or the jellies. We can use the net to avoid the mosquito bite. We should intake a lot of water and electrolyte supplements. We should take bed rest for few days. We need to see the doctor as soon as we see the symptoms of dengue fever.

Things we don t have to do, do not use disprin or the voveran tablet during the fever because these are the blood thinners. Do not avoid or delay the treatment. As we see the symptoms like bleeding from anywhere on the sight and black stool, continuous vomiting and severe weakness and continuous fever which leads to fainting.

These are the serious symptoms which should be immediately taken care of and we should seek the help of the doctor. It is a preventable disease. We should take care of the blood testing where we find the dengue test at initial four to five days, likely to be positive and antibody test after four to five days, is likely to be positive. Platelets are falling after four to five days and remain for the next three to four days and then it automatically starts. Some people require hospitalization as well as the platelet transfusion. The upper limit of the platelet is up to ten to fifteen thousand where we can prevent or avoid the platelet transfusion. But if it is going down lower or there is any sign of bleeding up to forty thousand then we have to give the platelet transfusion request.

If you need any of my help, I am available at Lybrate. My home clinic is Naman Medicare at Gurgaon, Sector IV.

Thank you
