How to safeguard and prevent Dengue Fever and report affected zones

Dengue fever is a mosquito-borne viral infection that has seen a worrying surge in Bengaluru this year. Here's a quick guide to understand the disease and how to stay protected.


Dengue is transmitted through the bite of Aedes mosquitoes, particularly the Aedes aegypti species. These mosquitoes thrive in stagnant water, making Bengaluru's uneven infrastructure a breeding ground during monsoon seasons.


Dengue symptoms can range from mild to severe and typically appear 4-10 days after being bitten. Here are some common signs:

  •  Sudden high fever
  •  Severe headache
  •  Pain behind the eyes
  •  Muscle and joint pains
  •  Nausea and vomiting
  •  Skin rash

Dengue fever can range from a mild illness to a life-threatening condition. While most people experience a flu-like illness with high fever, muscle aches, and a rash, a small percentage develop severe dengue. This is characterized by severe abdominal pain, persistent vomiting, and bleeding from the nose, gums, or even internally.  This can lead to a rapid drop in blood pressure (shock), which can be fatal if not treated promptly.  Early diagnosis and supportive care are crucial to prevent complications and ensure a full recovery

Prevention is Key

With no specific treatment for dengue, prevention is crucial. Here's what you can do:

How to safeguard and prevent Dengue Fever

  • Eliminate mosquito breeding sites:  Be a vigilant inspector around your home and neighborhood. Look for and eliminate stagnant water in:
    •      Discarded tires, even small ones like those used for toys.
    •      Flower pots, including saucers underneath.
    •      Clogged drains and gutters.
    •      Unused coolers and tanks.
    •      Pet bowls that don't get refreshed daily.
    •      Anything else that can hold water after rain or for extended periods.
  •  Use mosquito repellents: Apply repellents containing DEET, picaridin, or IR3535 on exposed skin.
  •  Wear long-sleeved clothing and pants: Cover up, especially during dusk and dawn when mosquitoes are most active.
  •  Install mosquito nets: Use bed nets while sleeping to prevent bites.
  •  Stay informed: Stay updated on fogging schedules in your area and cooperate with fogging initiatives.

Be Alert, Stay Safe

If you experience dengue symptoms, consult a doctor immediately. Early diagnosis and proper hydration are essential for a speedy recovery. By taking these preventive measures and staying informed, you can significantly reduce your risk of contracting dengue.
