What Is Dengue Fever?
A virus spread by mosquitoes that can be lethal and produces severe flu-like symptoms is called dengue fever. This article helps you understand Dengue Fever, Symptoms, Causes, Prevention, Diagnosis, and Treatments.
In 2018, the monsoon is expected to be very high.The World Health Organization (WHO) reports an increase in dengue cases over the past few years.
Dengue viruses, of which there are four known serotypes that can infect people, are the source of dengue fever.
Serotypes are extremely closely related groups of bacteria that can be distinguished from one another by minute differences in antigens foreign substances that cause the body to create antibodies or in the way the body reacts to the antigen.
There are four distinct serotypes of dengue viruses that are known to infect people, and these viruses cause dengue fever.

- Skin rashes
- Vomit three or more times per day
Dengue Fever Transmission
- Dengue virus is transmitted primarily by female Aedes mosquitoes, which bite during the daytime.
- These mosquitoes breed in wet areas, typically within 200 meters of their breeding site, and do not breed in creeks, swamps, or pools or other bodies of water.
- Humans are the primary source of viral transmission. Female mosquitoes ingest the dengue virus from the blood of infected individuals.
- After infecting the mosquito's midgut, the virus spreads throughout its body over eight to twelve days.
- The mosquito remains infective for life and can transmit the virus to other humans through bites.
- Environmental conditions, especially temperature, affect the virus's incubation period in mosquitoes.
Diagnosis of Dengue Fever
Blood tests are used by doctors to detect viral antibodies or infection. If you get dengue symptoms after visiting outside the nation, consult a doctor to see if you are infected.
Severe Dengue Fever
Severe dengue fever is considered if the patient is from dengue risk presenting with fever from over 2 to 7 days with the following features:
- Evidence of plasma leakage, such as:
- High or progressively rising haematocrit
- Pleural effusions or ascites
- Circulatory compromise or shock (cold and clammy extremities, weak or undetectable pulse, narrow pulse pressure, un-recordable blood pressure)
- Significant bleeding
- An altered level of consciousness (restlessness, coma)
- Severe gastrointestinal involvement (persistent vomiting, increasing or intense abdominal pain, jaundice)
- Severe organ impairment (acute liver failure, acute renal failure) or other unusual manifestations
Treatment of Dengue Fever
Looking at how severe the dengue fever is, the doctors recommend some of the following tips and procedures to recover from dengue fever.
- Increasing fluid intake and using paracetamol rather than aspirin to treat fever and pain (aspirin may cause bleeding)
- Aspirin should not be given to children under 12 years of age unless recommended by a doctor
- Transferring blood under doctor diagnosis
- Special care at the hospital
- continuous Observation
However, watching out for some signs and symptoms of Dengue fever while recovering is important. Call your doctor if you find below severe dengue symptoms or consult a doctor immediately.
- Decreased urination
- Few or no tears
- Lethargy or confusion
- Dry mouth or lips
- Cold or clammy extremities

Book an AppointmentPrevention of Dengue Fever
- It's normally not necessary to keep someone with dengue fever out of daycare, preschool, school, or the workplace, but they shouldn't go somewhere where they could get bitten by mosquitoes. If this is not feasible, kids should remain at home for three to five days, or until they have lowered their temperature and are no longer contagious.
- There isn't a vaccination to shield people against this virus.
- Preventing sickness requires both personal protection and controlling mosquito populations in the environment.
- Keep mosquitoes from getting near an infected person who is feverish.
- In dengue-affected locations, take precautions against mosquito bites at all times.
Frequently Asked Questions
Mild dengue fever is characterised by a high fever and flu-like symptoms. Dengue hemorrhagic fever, also known as severe dengue fever, can result in severe bleeding, a sudden drop in blood pressure (shock), and death.
Dengue fever symptoms typically last 2–7 days. Most people will recover within a week.
Dengue fever is characterised by an abrupt onset of high fever, headache, myalgias, arthralgias, and generalised lymphadenopathy, followed by a rash that appears with a second temperature rise following an afebrile period. Cough, sore throat, and rhinorrhea are examples of respiratory symptoms.
According to doctors, the majority of dengue cases can be treated in hospital outpatient departments, with only the most severe cases requiring hospitalisation. The World Health Organization (WHO) has issued an advisory on the symptoms that should lead to hospitalisation in patients.
