Dengue Fever: Symptoms, Causes and Treatment

A tiny mosquito bite can do enormous damage! Everyone is aware of how critical dengue is. However, being aware a little bit more about dengue fever, its signs, and treatments might protect you and your loved ones.

Dengue fever cannot be overlooked as a simple viral fever. It’s relatively dangerous. Since the initial symptoms are similar, it can be difficult to know in the first instance, exactly what disease you are suffering from.

In this article, we have tried to discuss in detail the symptoms, causes, and remedies of dengue fever. As a result, you can diagnose dengue at the right time and start the right treatment.

What is Dengue Fever?

Dengue (Dengey) fever is a mosquito-borne illness. When a person is stung by a mosquito carrying the dengue virus, he or she becomes infected within four to six days. If a female Aedes mosquito bites those affected persons, that mosquito will now carry the dengue virus.

It's a common disease in tropical and subtropical regions of the world like Bangladesh, and India. Mild dengue fever causes a high fever and flu-like symptoms. However, those who have been infected with dengue fever in the past are at risk, if the disease occurs later.

Types of Dengue Fever

Doctors say there are two types of dengue fever: “classical” and “hemorrhagic”.

Classical dengue fever typically disappears after two to seven days. Hemorrhagic cases appear to be risky. After approximately five to seven days, a person infected with this dengue can become critically ill.

In the hemorrhagic case, the patient bleeds, the blood flow level decreases, and the blood plasma is emptied. Dengue shock syndrome occurs in some cases. Blood pressure drops dangerously.

Occasionally, the affected person bleeds out of the mouth, gums, and nose. Sometimes blood may also come out of the stool. Women with dengue also bleed excessively during menstruation. Some even have internal hemorrhage under the skin due to reduced blood platelets or microcirculation.

The situation becomes more complicated if the patient's hands and feet start getting cold and the blood pressure drops. During this time, the affected person sweats profusely. It also caused him or her to become restless. Some people vomit or become nauseous.

Some patients may experience issues such as low white blood cell counts, electrolyte imbalances, liver problems, or brain bleeding during this time. There is a possibility that they will go into shock. Unfortunately, it can also result in the deaths of a significant number of patients.

Causes of Dengue Fever 

Most importantly, do people get dengue when bitten by Aedes mosquitoes? Doctors disagree on this point. They claim that there is no risk of contracting dengue through the bite of an Aedes unless a virus in the environment is transmitted to it. Female Aedes mosquitos spread viruses. They transferred the virus from infected to healthy individuals.

In simple words, Dengue fever is caused by the Aedes mosquito. When a person is bitten by a mosquito that carries the dengue virus, the person becomes infected with dengue fever within four to six days.

Symptoms of Dengue Fever

Dengue symptoms can appear three to fifteen days after being bitten by an Aedes mosquito carrying the virus. As a result, everyone should be aware of the symptoms of dengue fever. Among these symptoms are:

  • Body temperature can fluctuate between 102 and 105 degrees Fahrenheit.
  • Headache,
  • Vomiting,
  • Pain behind the eyes,
  • Red spots on the skin (rash),
  • Feeling cold in the body,
  • Loss of appetite,
  • Constipation,
  • Taste changes,
  • Decreased heart rate and lower blood pressure
  • Muscle Pain

Dengue Hemorrhagic Fever is the most complicated condition. In addition to the signs and symptoms of classical dengue fever, other problems may occur like bleeding starting from different parts of the body, water in the chest, water in the stomach, etc. may appear. Many times the patient's liver is affected and complications such as jaundice and renal failure due to kidney disease may occur.

The worst form of dengue fever is dengue shock syndrome. Its symptoms include sudden drops in blood pressure; very weak and rapid pulses; cold hands, feet, and other parts of the body, and decreased urine. The patient may suddenly lose consciousness or even die.

Steps and Precautions to Prevent Dengue

Because Aedes mosquitos bite during the day, you must use mosquito nets or coils while sleeping. In dark areas of the house, mosquito repellants or sprays can be used. Wear long-sleeved clothing to be safe during this time.

Aedes mosquitos generally breed in clean water. As a consequence, take precautions to ensure that water does not accumulate in the office, home, or surrounding areas. 

If you notice any water accumulation, change the water every 2-3 days. Many times, water accumulates in places like flower trays, air conditioning, or under the fridge. Keep those places clean during the dengue season.

Instead of panicking, if you have dengue fever, be cautious. If you are aware of some warning signs in this regard, you could perhaps stay alert. 

Consult a doctor immediately if you experience unusual weakness, incoherent speech, persistent vomiting, severe abdominal pain, red rash, shortness of breath, cold hands and feet, blood in the urine, reduced urine output, anus, or excessive bleeding during menstrual cycles.

Who is at Great Risk?

Dengue fever is more common among kids under one year old as well as in those over the age of 65. Pregnant women, people who are overweight, people with diabetes, high blood pressure, heart problems, or people who take dialysis regularly are advised to stay in the hospital from the beginning of dengue fever.

Apart from this, be careful of dengue fever. If you have a fever during this time, you should first consult an experienced MBBS doctor. You can take this advice on video calls from home on the DocTime app. You can communicate with the doctor via video calls at any time. Complications can be prevented if the doctor's advice is followed at an early stage.

Doctors recommend getting an NS1 dengue test within the first 5 days of the onset of fever. There is also advice for the CBC, SGPT, and SGOT tests.

All of these tests can be accomplished at home by using the DocTime app. Qualified lab technicians will collect test samples from your home. The report will also be mailed to you within 24 hours.

Treatment for Dengue Fever

If you have any symptoms, you should consult a doctor. Taking medicine without a doctor's advice or taking any action on your own can lead to serious consequences. 

To protect yourself after infecting dengue fever, it’s best to start home care and treatment as per a doctor's advice.

What to do to Get Cured of Dengue Fever?

To reduce fever, only Paracetamol can be used. This medicine should be taken every 6 to 8 hours, depending on the level of fever.

Doctors recommend no more than 4 tablets per day. Taking more than this amount can result in various complications, including liver problems.

Doctors strictly prohibit using aspirin or non-steroidal anti-inflammatory drug (NSAID) group analgesics to diagnose dengue cases.

To reduce fever, wipe your body, or take a bath with lukewarm water. Because dengue patients are often tired, they need to get enough rest. Heavy work or overexertion is prohibited for 7 to 10 days after the onset of symptoms. However, simply sitting or lying down is not permitted. Normal daily activities, such as walking, should be continued. It is best to stay indoors at this time.

What to Eat If You Have Dengue Fever?

Water replacement is the most important part of treatment for dengue. During this time, two and a half to three liters of water per day should be consumed to keep the body hydrated.

Besides that, fluids such as saline, soup, water, fruit juice, and milk should be consumed in large quantities. Apart from this, you should eat a lot of protein and iron foods. Fish, chicken meat, lean red meat, eggs, milk, and dairy products are high in protein, so these foods should be eaten more at this time. These foods help in boosting immunity.

Awareness is a crucial way to prevent dengue fever. Be aware that Aedes mosquitoes cannot breed, and beware of Aedes mosquito bites during the day. It is possible to build resistance against dengue fever only through awareness.

Frequently Asked Questions about Dengue Fever

How to recognize an Aedes mosquito?

Anyone with a keen eye can notice the Aedes mosquito that transmits the dengue virus. This medium-sized black-and-white striped mosquito has hairy trunks. They also have a white spot on the back of their heads, which differentiates them from common mosquitoes.

When do Aedes mosquitoes sting?

Dengue fever is more common from July to October due to the proliferation of Aedes mosquitoes. Almost everyone is aware that the Aedes mosquito only bites during the day. However, the day does not begin in the morning. They bite from dawn to dusk, just before sunset. 

Aedes mosquitoes, in particular, are most active in the early morning and just before dusk. According to doctors, they don’t bite at night. After lunchtime, a lot of people like to take a nap. You should also exercise caution when sleeping at that time. Children, in particular, cannot be neglected.

Where does the Aedes mosquito sting?

Many people believe that the Aedes mosquito only bites the legs. This is also a misquotation. Because the legs are more open than other parts of the body, mosquitoes prefer to bite there. However, if given an opportunity, this dreadful mosquito can bite any part of the body! Because of that, it would be a mistake to classify any fever as common during this season!

How many days after a mosquito bite is infected with dengue? 

Dengue symptoms appear three to fifteen days after being bitten by an Aedes mosquito. 

When (time) do Aedes Mosquitoes Bite More Frequently? 

Aedes mosquitoes are usually active in the early morning and just before dusk. 

Is Dengue a Contagious Disease?

Dengue fever is not spreadable. There is no risk of spreading the disease to others by touching and sleeping in the same bed or using anything used by a person with dengue fever. As a result, there is no reason to avoid contact with a dengue patient, nor is there any reason to isolate him or her.
