Dengue Fever: Causes, Symptoms & Treatment
Introduction
As the climate changes, there are various illness that start occurring. From cold and cough to dengue, everything disrupts our daily lives. But there is one disease that is a growing concern. It is impacting millions of people globally. It is dengue fever.
It is a common fever now but requires quick treatment. In April 2024, WHO confirmed that there are more than 7.6 million cases of dengue. Thats not it! There were 16,000 severe cases. It also led to 3,000 deaths.
This is an alarming situation. With so many people at risk, it becomes important to understand what this fever is. How it is caused and how it can be avoided. Well, this might sound a bit challenging but with the right information, you can avoid this greatly.
So, let us get started here.
What is Dengue Fever?
Dengue is a mosquito-borne viral fever. It is caused by Aedes aegypti mosquito. It can be asymptomatic to severe in nature. The symptoms usually appear within 3 to 14 days of infection.
Dengue is usually mild. But at times, it can get serious. In severe conditions, patients can face serious complications such as;
Bleeding
Low platelet counts
Plasma leakage
This can lead be fatal and can lead to conditions like shock and organ failure.
Today, millions of people are impacted by this dengue virus. This is now transformed to a fatal disease at certain tropical and subtropical regions particularly in Southeast Asia, Latin America, and parts of Africa.
Hence, educating people about it becomes important than ever.
Causes of Dengue Fever
You all must have heard of dengue fever during monsoon. It is caused by the dengue virus which is a member of the Flavivirus genus. There are four distinct serotypes of the virus:
DENV-1
DENV-2
DENV-3
DENV-4.
The disease is transmitted by mosquito bites which are active in daytime. The key points that you must know for its causes are as follows:
Transmission
A person gets this virus when an infected mosquito bites. This is also the primary source of transmission.
Infection Cycle
The incubation period is 3-14 days. The virus starts spreading through the bloodstream. This spread the infection which can lead to severe condition, if not treated.
Secondary Transmission
A mosquito bite is the primary cause of transmission. But there are other reasons, too. Some of them are:
Infected blood products or organ donations.
Rare cases of vertical transmission from mother to child during pregnancy or childbirth.
Environmental Factor
High-risk factors for dengue infection include living in or traveling to endemic areas where:
There is poor sanitation.
There are standing water bodies. This serve as breeding sites for mosquitoes.
Symptoms of Dengue Fever
When it comes to symptoms, initially it appears like normal fever. But gradually symptoms start developing and it can be confirmed from blood test.
The common symptoms are:
Abrupt onset of high fever
Severe frontal headache
Pain behind the eyes, which worsens with eye movement
Muscle and joint pains
Loss of sense of taste and appetite
Measles-like rash over the chest and upper limbs
Nausea and vomiting
In cases of severe dengue, additional symptoms may arise, such as:
Frequent vomiting (with or without blood)
Bleeding from the nose, mouth, or gums
Skin rashes
Sleepiness and restlessness
Thirst and dry mouth
Rapid weak pulse
Difficulty in breathing
In case of serious condition, consult the doctor at the earliest.
Treatment for Dengue Fever
This is very important to know. As of today, no specific treatment is there. Supportive care is the main treatment provided. The idea is to manage the symptoms and avoid case from worsening. So, here are the common treatment choices as follows:
1. Hydration
Dehydration is common when you are ill. And if you have fever and vomiting, its chances it increases. This can lead to multiple complications. So, its important that you take care of it on time. This is how you can ensure hydration:
Drink plenty of fluids like water
Consume oral rehydration solutions
Include natural drinks like coconut water and herbal teas
Go for electrolyte-rich beverages
Avoid beverages like tea, coffee, alcohol, and sugary soft drinks
Good nutrition is important as well.
2. Rest
Rest is essential for recovery from dengue fever. Adequate rest helps the body heal and can improve overall comfort. To promote effective recovery:
Prioritize bed rest to facilitate healing
Limit physical activity to reduce fatigue
Avoid stress and anxiety to promote relaxation
Sleep for at least 8-10 hours per night
Sleep and recovery are too connected, so focus on it
3. Monitoring Symptoms
Your symptoms can change over time. Hence, you need to track them constantly. To stay vigilant:
Track symptoms regularly and note any changes
Seek medical attention if severe manifestations occur, such as persistent vomiting or severe abdominal pain
