Dengue Symptoms

Introduction 

Finding out the symptoms of Dengue earlier is significant as it helps in the faster treatment and prevents any further complications. The dengue fever early symptoms are commonly seen 4 to 10 days after an infected mosquito bite. The symptoms of Dengue in babies include a sudden high fever (up to 104°F), Irritability, rash, Vomiting or diarrhoea, along with other symptoms such as sleepiness, lack of energy, and reduced appetite. 

To identify the symptoms of Dengue, a medical professional can go through blood tests, like NS1 antigen detection, IgM and IgG antibody tests, and molecular tests (like PCR) to determine the presence of a virus or its components. But, finding out the Dengue symptoms in adults at home is also possible. 

A serum sample is used for dengue testing or to identify the dengue symptoms. Dengue fever is seen in above 100 countries, especially in tropical and subtropical regions, and they have the highest incidence in Southeast Asia, the Western Pacific, Latin America, and Africa. Dengue fever have caused an estimated 20,000 to 36,000 deaths yearly. Thus, it is better to find out the symptoms of Dengue. 

Symptoms of Dengue 

Recognizing dengue fever symptoms is crucial for early diagnosis and management. Typically appearing 4-10 days after an infected mosquito bite, initial signs include a sudden high fever, severe headache, and pain behind the eyes.

Sufferers often experience intense joint and muscle pain, which is why dengue is nicknamed "breakbone fever." A characteristic skin rash may also develop. In severe cases, warning signs like severe abdominal pain, persistent vomiting, and bleeding from the nose or gums can occur.

Prompt medical attention is essential if any of these symptoms appear.

Types of Dengue 

There are four types of Dengue virus types: dengue-1, dengue-2, dengue-3, and dengue-4.

• Dengue virus type 1 (DENV-1) is one of the serotypes of arthropod-borne viruses (arbovirus) that result in Dengue. 
• Dengue virus type 2 (DEN-2) have the ability to result in the dengue hemorrhagic fever, that have been shown belonging to the Southeast (SE) Asian genotype.
• Dengue virus type 3 were isolated from patients in Brazil from 2002 through 2004. These isolates were assigned genotype 1, as per phylogenetic analyses. 
• Dengue virus type 4 is one among the four dengue virus serotypes (DENV-1, DENV-2, DENV-3, and DENV-4) that causes dengue fever. It was first recognised in the Western Hemisphere in 1981.

Causes of Dengue

• Dengue virus is spread by a female Aedes mosquito, which generally bites an infected person in the morning to take a blood meal, and then it spreads the virus any time of the day. 
• Within 2-10 days, the mosquito becomes infected, and the virus spreads to other tissues and is released into saliva. 
• When the mosquito bites an uninfected person, the person becomes infected. The mosquito is generally infected for a lifetime.
• The dengue virus also spreads via blood or organ donation from an infected person.

• Be aware of dengue outbreaks in your area and medical advice provided by the medical staff.

How is Dengue Fever Diagnosed?

Dengue fever is diagnosed through blood tests that determine the virus or antibodies against it, using tests like NS1 antigen detection and serological tests (IgM and IgG).

Conclusion

The dengue fever first symptoms include a sudden high fever, heavy headache, pain behind the eyes, nausea, vomiting, muscle and joint pain, and a rash, that appears 4-10 days after an infected mosquito bite. The dengue fever first symptoms are typically diagnosed using blood tests that detect the virus or antibodies against it. 

The medicines and treatment methods to manage the symptoms help the dengue fever symptoms day by day. The mild dengue symptoms are usually manageable with rest, hydration, and acetaminophen to control fever and pain.
