What is Dengue? Causes, Symptoms, preventive measures, and Treatment

Updated: Jul 7, 2022

Dengue is the most common mosquito-borne viral disease and has become a leading cause of hospitalization and death among children and adults. It is usually transmitted by mosquitoes which are closely related to the viruses that causes illnesses like West Nile infection and yellow fever. These virus weakens the immune systems and enhances greater risk for developing dengue hemorrhagic fever. The common risk factors for dengue are rainfall, temperature, relative humidity and unplanned rapid urbanization.


Transmission sources


Following are the two key sources:-


A) Mosquito-to-human transmission


Here the infected female mosquitoes; the Aedes aegypti mosquito, bites and transmits the virus to humans.


B) Human-to-mosquito transmission


Mosquitoes can become infected from people whose blood is already infected with a dengue virus (DENV).


Symptoms of Dengue


Symptoms are mild and can be mistaken with flu or other viral infection signs. It usually lasts for 2-7 days, after an incubation period of 4-10 days after the bite from an infected mosquito.


Following are common signs:


· Severe headache and fever

· Pain behind eyes

· Severe muscle and joint pains

· Nausea, fatigue and restlessness

· Persistent vomiting

· Swollen glands

· Severe abdominal pain

· Rapid breathing

· Mild bleeding (nose bleed, gum bleed and easy bruising)

· Skin rashes


Causes of Dengue


Dengue never directly spreads from one person to another, rather it is mostly caused by mosquito bite virus (Genus Aedes) - DENV-1, DENV-2, DENV-3 and DENV- 4. When a dengue infected person is bitten by a mosquito, the virus enters the mosquito. When the infected mosquito bites another person, the virus enters that person's bloodstream and causes the person to get affected by dengue.


Preventive Measure For Dengue


The best way to prevent the disease is to keep the mosquitoes away.


Following tips are beneficial:


i) Use mosquito repellents both indoors and outdoors.

ii) Wear clothes that minimizes skin exposure.

iii) Use air conditioners, if indoors.

iv) Close all windows and doors during the evening.

v) Use mosquito nets while sleeping.

vi) Cover, empty and clean domestic water storage containers on a weekly basis.

vii) Emergency vector control measures such as spraying insecticides in the air during outbreaks may be used by health authorities.

viii) Stay hydrated and drink lots and lots of water.

ix) Maintain good hygiene practice.


Treatment of Dengue


Dengue can be life-threatening and needs to be treated as soon as possible. By including some lifestyle changes and consumption of certain foods can potentially strengthen inner healing and help the body to fight against dengue.
