Dengue is caused by which Mosquito: Introduction
As we are heading towards the pre-monsoon season, the threat of Dengue is also looming large. With the onset of rains, stagnant water accumulates in various containers, providing breeding grounds for Aedes mosquitoes, the carriers of the Dengue virus. This time of the year poses a heightened risk of Dengue outbreaks, especially in regions with inadequate sanitation and mosquito control measures.
Because of its crippling effects, the name “Dengue fever” evokes anxiety in areas where tropical climates are prevalent. But what precisely is the cause of this common illness? When we examine the complexities of dengue, we find that the mosquito—a small but mighty creature—plays a crucial role. The purpose of this page is to clarify the relationship between dengue and its main carrier by illuminating important details about symptoms, prevention, treatment, and transmission.
Dengue is caused by which Mosquito: Understanding Aedes Aegypti mosquito
Let’s learn the scientific term for the aggressor of this crippling disease: The Aedes Aegypti mosquito.
The dengue virus, which is a member of the Flaviviridae family, is what causes dengue fever. The virus has four different serotypes that might cause the illness: DEN-1, DEN-2, DEN-3, and DEN-4. After contracting the infection, a person may have a variety of symptoms, such as a high temperature, excruciating headaches, rash, discomfort in the joints and muscles, and, in extreme situations, bleeding and organ failure. If treated slowly, dengue hemorrhagic fever and dengue shock syndrome—which are marked by bleeding, low platelet counts, and plasma leakage—can be fatal.
Aedes Aegypti and Dengue
Now that we know, the main vector that spreads the dengue virus to people is the Aedes aegypti mosquito.
This type of mosquito is ideally suited to life in cities; it thrives in places where there is standing water, like flowerpots, abandoned tires, and exposed water storage containers. Because female Aedes mosquitoes need blood meals to grow and produce eggs, they are effective vectors for spreading the dengue virus from sick people to healthy people while they are feeding.

Characteristics of the Dengue mosquito
When trying to prevent dengue, it can be crucial to identify the Aedes aegypti mosquito. The following are some of this species’ most important traits:
Unique Look: Aedes aegypti mosquitoes are petite, dark-colored insects with a lyre-shaped pattern on their thorax and characteristic white markings on their legs.
Daytime Feeding Habits: Aedes aegypti mosquitoes are active day feeders, preferring to bite in the early morning and late afternoon, in contrast to other mosquito species that feed mostly at dawn and nightfall.
Urban Adaptation: Aedes aegypti mosquitoes have adapted well to living in urban settings; they can be found flourishing in places with poor access to sanitary facilities and clean water.
Breeding Sites: It is imperative to get rid of flowerpots, abandoned tires, and water storage containers since these mosquitoes deposit their eggs in these and other containers that hold stagnant water.

Dengue Fever Symptoms
The mentioned symptoms can vary from person to person. But the following are some of the common points:
- High fever, often reaching up to 104°F (40°C)
- Severe headache, typically located behind the eyes
- Muscle and joint pain, often described as “breakbone fever”
- Nausea and vomiting
- Skin rash, characterized by small red spots
- Mild bleeding, such as nosebleeds or gum bleeding
- Fatigue and weakness
- Abdominal pain or discomfort
- Swollen lymph nodes
It is important to remember that the severity of dengue symptoms might vary from person to person. Serious cases of dengue fever might result in complications like dengue shock syndrome or dengue hemorrhagic fever, which require emergency care. Seek medical attention immediately if you or someone you know has any of these symptoms, particularly before, during, or after visiting regions where dengue is widespread.
What are the preventive measures against Dengue?
To reduce the risk of dengue, the following are some important points:
- Eradicate stagnant water: Make sure that you cover the lid of the buckets, and empty the containers that can collect water, such as flower pots, tires, and buckets, to prevent mosquito breeding.
- Use repellents: Make sure that you apply mosquito repellent before going out.
- Wear proper clothes: Make sure that you wear full-sleeve shirts, full pants, socks, and everything you need to cover your body.
- Install proper screens. Ensure your house or living space is covered to prevent mosquito bites.
- Use Mosquito nets: Install mosquito nets, especially during the night hours.
- Avoid going out during peak hours: Make sure you avoid going out during the peak hours when mosquitoes are active.
- Participate in community clean-ups: You should participate in the community clean-up drives to stop mosquito breeding sites.
- Educate everyone: You should inform everyone about Dengue prevention and encourage them to take the necessary steps to protect everyone from the dengue.
By following the above steps, we can proactively stop the spread of mosquito breeding, which will also stop Dengue.
