By the bite of a mosquito carrying one of the dengue viruses, dengue fever is a disease that can get contracted. Dengue hemorrhagic fever, an illness that can be fatal, usually only has mild flu-like symptoms in the beginning. Severe symptoms are more likely to develop if you contract the infection again. You can seek virtual assistant healthcare to get medical assistance. If you’ve had dengue before, you can still receive the vaccination.
What Causes Dengue Fever?
Aedes mosquitoes are widespread in tropical and subtropical regions worldwide and transmit four closely related viruses that cause dengue disease. The Aedes mosquito has the potential – to spread the dengue virus after biting a victim who has contracted it. The individual who gets bitten by this mosquito runs the risk of contracting the dengue virus and developing dengue fever. Direct transmission of the virus is not possible.
Dengue fever can develop into dengue hemorrhagic fever, a more severe illness (DHF). DHF needs to get treated soon away because it may be fatal.
Symptoms of dengue
About 5 to 8 days after contracting the infection – dengue symptoms appear suddenly.
Among the symptoms are:
- a fever or sensation of being hot or shaky
- a terrible headache
- eyesight discomfort
- an ache in muscles and joints
- Having a sick feeling
- an all-over crimson rash
- stomach discomfort and appetite loss
Although you can feel exhausted and slightly ill for a few weeks after, the symptoms usually go away in about a week.
After the initial symptoms, severe dengue might occasionally appear.
Knowing when to seek medical advice
Up to two weeks after visiting a region where the dengue virus is present, consult your doctor or virtual health care assistant if you experience a fever or flu-like symptoms.
Don’t forget to disclose your vacation itinerary to the nurse or doctor.
If you get symptoms while traveling or residing in a dengue-prone area, visit a doctor or hospital.
The method for diagnosing dengue
A blood sample is necessary for each method of diagnosing dengue illness. In the early days following infection, reverse transcriptase-polymerase chain reaction (RT-PCR), the gold standard, can be performed to detect the virus. There are also quick diagnostic tests that look for the NS1 protein generated by the virus. Serological techniques can verify a current infection—within the last three months—or a preexisting infection.
The Treatment for Dengue Fever
There is no particular therapy for dengue fever. Fluid intake in large quantities to avoid dehydration and ample rest are used to treat mild instances. Headaches and pain from dengue fever can be relieved with acetaminophen-containing painkillers. Avoid using painkillers that contain aspirin or ibuprofen since they increase the risk of bleeding.
A week or two is usually enough time for dengue fever to pass without causing any long-term issues. Receive immediate medical attention if someone has severe disease symptoms or if symptoms worsen in the first or second day or two after the fever has subsided. DHF, a medical emergency, could be indicated by this.
In a hospital setting – doctors administer intravenous (IV) fluids and electrolytes (salts) to replenish fluids lost through vomiting or diarrhea. In more severe circumstances, doctors might need to perform a blood transfusion.
