Dengue Fever: Symptoms, Causes, Cure, and Prevention

30 September, 2021 Anuja Sahi

Dengue fever (DENG-gey) is a mosquito-borne sickness that primarily affects tropical and subtropical regions of the world. Dengue fever is characterized by a high fever and flu-like symptoms. Dengue hemorrhagic fever, a severe form of dengue fever, can result in major bleeding, a drop in blood pressure (shock), and death. Dengue fever is also known as break-bone fever.

Dengue fever affects millions of people each year throughout the world. Southeast Asia, the western Pacific islands, Latin America, and Africa are the most prevalent dengue fever hotspots. However, the disease has spread to new locations, including isolated outbreaks in Europe and the United States’ southern parts.

Symptoms of Dengue fever

High fever followed by headaches, joint and muscular discomfort, vomiting, and a rash is all symptoms of dengue fever. Dengue hemorrhagic fever is a type of dengue that produces bleeding from the nose, gums, and under the skin. Dengue fever can also progress to dengue shock syndrome, which results in severe bleeding and shock. The fever can also be fatal in certain cases.

Causes and consequences of Dengue fever

Humans develop dengue fever after being bitten by infected female mosquitoes. The principal vectors are Aedes mosquitos. An infected mosquito can spread the virus for the remainder of its life after the virus has been incubated.

Mosquitoes like this can be found in tropical and subtropical areas all over the world. They like to breed in man-made containers (such as buckets of water, potted plants, and so on) and reside in metropolitan areas.

Dengue is a disease that affects a wide range of people. This can range from asymptomatic infection (when people are unaware they are infected) to severe flu-like symptoms in those who are affected. Although rare, some persons get severe dengue, which can result in a variety of consequences including severe bleeding, organ damage, and plasma leakage. When severe dengue is not treated properly, there is an increased chance of mortality.

Warning signs of Dengue fever

Immediately rush to your doctor or clinic if you find any of the given below symptoms of dengue:

  • Abdominal pain
  • Tenderness
  • Bleeding from the nose or gums
  • Headaches
  • High fever
  • Feeling tired, or irritable

Cure of dengue

Despite taking medicines and consulting a doctor, there are some other ways in which dengue can be cured:

  • Drink plenty of fluids
  • Rest as much as possible
  • Take paracetamol as advised by your doctor
  • In case of severe symptoms or if the condition worsens, consult your doctor and get admitted to the hospital

There is no specific treatment for this condition. Dengue fever usually passes in two weeks for the majority of persons. Until then, staying hydrated, relaxing, and using non-aspirin fever-reducing medications may be beneficial. The most severe varieties of dengue usually necessitate a trip to the hospital for fluids.

What is the best time to consult a doctor if you have signs of dengue?

Dengue fever is a medical emergency that can be fatal. If you have recently visited a region where dengue fever is known to occur, you have had a fever, and you have developed any of the warning signs, seek medical help right away. Severe stomach discomfort, vomiting, difficulty breathing, or blood in your nostrils, gums, vomit, or feces are all warning indications.

How transmission of dengue fever takes place?

Infected female mosquitoes, typically the Aedes aegypti mosquito, transmit the virus to people through bites. Other Aedes species can also operate as vectors, although their role is secondary to that of Aedes aegypti.

The virus replicates in the mosquito midgut after it feeds on a DENV-infected person before spreading to secondary tissues, such as the salivary glands. The extrinsic incubation period is the time between swallowing the virus and transmitting it to a new host (EIP). When the ambient temperature is between 25 and 28°C the EIP takes about 8-12 days. Extrinsic incubation period variations are impacted by a number of parameters including the magnitude of daily temperature fluctuations virus genotype and initial viral concentration, among others. Now the mosquito is capable of transmitting viruses for the rest of its life.
