Delivering toChennai
Dengue fever is a mosquito-borne viral infection that has become a major public health concern, especially during the monsoon season. In recent weeks, dengue cases in Chennai have been increasing, making it essential to understand its symptoms, causes, and available treatments.
At Medizinhub , we aim to spread awareness and provide timely dengue testing and fever consultations for early detection and better care.
Dengue is caused by the Dengue virus (DENV), which spreads through the bite of an infected Aedes aegypti mosquito.
These mosquitoes are active during the daytime, especially early morning and late afternoon.
Dengue is not contagious — it does not spread directly from person to person, but only through mosquito bites.
Recognizing the signs early is crucial for faster recovery.
Common symptoms of dengue fever include:
Sudden high fever (up to 104°F or 40°C)
Severe headache and pain behind the eyes
Muscle, bone, and joint pain (often called “breakbone fever”)
Nausea, vomiting, or loss of appetite
Mild bleeding (nosebleeds, gum bleeding, easy bruising)
Skin rash appearing a few days after fever begins
If any of these symptoms last more than two days, get a dengue test near you immediately.
Dengue fever is caused by the Dengue virus (DENV), which has four distinct variants — DENV-I, DENV-II, DENV-III, and DENV-IV.
These are known as serotypes, and each can cause infection.
When infected with one serotype, the body develops lifelong immunity against that specific variant.
However, this protection does not extend to the other three types.
If reinfected by a different dengue variant, the immune system may overreact — a process known as antibody-dependent enhancement (ADE).
This can lead to more severe forms of dengue:
Dengue Hemorrhagic Fever (DHF): Characterized by bleeding, low platelet count, and plasma leakage.
Dengue Shock Syndrome (DSS): A life-threatening condition causing dangerously low blood pressure and organ failure.
Dengue has four virus variants (DENV-I to DENV-IV).
Primary infection gives lifelong immunity only to that type.
Secondary infection with another variant increases the risk of severe disease.
Warning signs like persistent vomiting, abdominal pain, bleeding gums, or sudden fatigue need immediate medical care.
No specific cure exists — prevention and early diagnosis remain the best ways to protect yourself.
Severe dengue can be life-threatening if not treated promptly.
Watch for these warning signs:
Severe abdominal pain
Persistent vomiting
Bleeding gums or nose
Blood in vomit or stool
Fatigue or restlessness
Rapid breathing
Sudden drop in platelet count
If you notice these symptoms, seek immediate medical attention at your nearest Clinic or hospital.
There is no specific antiviral medicine for dengue, but supportive care helps manage symptoms and prevent complications.
