From mild fever to severe infections, mosquito-borne diseases can affect people of all age groups. In this blog, the leading internal medicine doctor in Gurgaon provides insight into the 4 most common diseases spread by mosquitoes, their symptoms, and prevention from mosquito-borne diseases
1. Dengue Fever
Dengue is one of the most widespread mosquito-borne diseases in the world, especially in tropical and subtropical regions like India, Southeast Asia, and Latin America.
Causes:
The dengue virus spreads through the bite of an infected Aedes aegypti mosquito, which is most active during daylight hours.
Symptoms:
- Sudden high fever
- Severe headache
- Pain behind the eyes
- Muscle and joint pain
- Skin rash
- Fatigue
- Nausea or vomiting
In severe cases, it can lead to Dengue Hemorrhagic Fever or Dengue Shock Syndrome, which requires immediate medical attention.
Prevention Tips:
- Use mosquito repellents
- Wear long sleeves and pants
- Avoid storing stagnant water in containers, flowerpots, and coolers
- Use mosquito nets while sleeping
2. Malaria
Malaria is another common mosquito-borne disease and is considered one of the deadliest.
Cause:
It is caused by Plasmodium parasites and transmitted through the bite of infected female Anopheles mosquitoes.
Symptoms:
- High fever with chills
- Sweating
- Headache
- Vomiting
- Muscle pain
- Weakness
If left untreated, malaria can lead to severe complications such as anemia, organ failure, or even death, especially in children and pregnant women.
Prevention Tips:
- Take anti-malarial medications if traveling to a high-risk area

- Drain out standing water
- Keep your surroundings clean
3. Chikungunya
Chikungunya is another mosquito-borne disease that leads to high fever and intense joint pain, often affecting multiple areas of the body.
Cause:
It is transmitted by the same Aedes mosquitoes that spread dengue, especially Aedes aegypti and Aedes albopictus.
Symptoms:

4. Zika Virus
Zika virus may not be as common in India as the others, but it is still a serious concern, especially for pregnant women.

Zika is also spread by Aedes mosquitoes, the same ones that transmit dengue and chikungunya.
Symptoms:
- Mild fever
- Rash
- Joint pain

The scary part is that the Zika virus can pass from a pregnant woman to her baby and may cause a birth defect called microcephaly.
