How To Prevent Dengue After Mosquito Bite? Expert Guided Insights To Stay Protected!

Dengue fever, a mosquito-borne viral infection, is a growing concern in India. According to a 2023 report by the National Vector Borne Diseases Control Programme (NVBDCP), India reported over 1.8 lakh dengue cases (National Vector Borne Diseases Control Programme, 2023), with some states experiencing severe outbreaks. Beyond the medical challenges, this illness can have far-reaching effects on families' financial well-being, consequently impacting broader society (Ganeshkumar and others, 2018).  

This viral illness, transmitted by the bite of infected Aedes mosquitoes, can cause a range of symptoms, from mild fever and headaches to severe complications like internal bleeding and shock. Notably, a person can be infected with dengue multiple times, as there are reportedly four types of dengue viruses capable of causing the illness. Presently, dengue is endemic in over 100 countries across various WHO regions, with Asia bearing the brunt of the global burden, accounting for more than half of the cases (WHO, 2020).   

While there's no specific treatment for dengue, preventing mosquito bites remains the cornerstone of protection. This blog empowers you with the knowledge to significantly reduce your risk of getting bitten by a dengue-carrying mosquito in the first place. We'll delve into the dengue mosquito biting time and equip you with the ability to identify dengue mosquitoes, differentiating them from other mosquito species.  

Furthermore, this blog explores the best practices for what to do if a dengue mosquito bites you, including recognising early warning signs of dengue fever and seeking prompt medical attention. Let's turn the tide on dengue fever in India, one informed and empowered citizen at a time!

How To Identify Dengue Mosquito? 

Identifying the Aedes mosquito responsible for transmitting dengue fever involves recognising specific physical characteristics and behaviours. Let’s have a thorough scrutiny on how to identify dengue mosquitoes:  

1. Distinct Appearance 

Aedes mosquitoes are relatively small and often have a dark body colouration, making them stand out from other mosquito species. One of their most recognisable features is the presence of distinct white markings on their legs and body. These markings are a visual cue for identification and vary in intensity and pattern across different Aedes species. The evolutionary purpose of these markings has yet to be entirely understood, but they may play a role in species recognition, camouflage, or thermoregulation. 

2. Striped Patterns 

A characteristic feature of Aedes mosquitoes is their striped pattern, which is evident on their legs and thorax. For example, Aedes aegypti, the primary vector for dengue fever, exhibits striking white stripes on its legs and a distinctive lyre-shaped pattern on its thorax. These patterns have evolved as a form of protective colouration or mimicry, aiding in camouflage and potentially deterring predators.  

3. Daytime Biting Behavior 

Unlike many other mosquito species that primarily feed during the evening or nighttime, Aedes mosquitoes are considered for their aggressive daytime biting behaviour. This behaviour is driven by several factors, including their preference for feeding on humans and their adaptation to urban environments. Aedes mosquitoes are opportunistic feeders and take advantage of human activity during the day to seek blood meals. This behaviour increases the likelihood of human mosquito contact and the transmission of diseases like dengue fever. 

4. Breeding Habits 

Aedes mosquitoes have adapted to breed in small, artificial water containers commonly found in urban and suburban areas. These breeding sites provide ideal conditions for mosquito larvae to develop and thrive, as they offer stagnant water with low oxygen levels. Aedes mosquitoes are particularly attracted to containers such as discarded tyres, flowerpots, and water storage containers, where they lay their eggs in clusters known as "egg rafts." By targeting these breeding sites for elimination and proper maintenance, communities can reduce mosquito populations and limit the spread of diseases like dengue fever.

How To Prevent Dengue After Mosquito Bite Or What To Do If Dengue Mosquito Bites? 

If you have been bitten by a mosquito suspected of carrying the dengue virus, there are several steps you can take to minimise the risk of contracting dengue fever: 
 

1. Clean the Bite Area 

Wash the bite site with soap and water as soon as possible to reduce the risk of infection. This helps remove potential contaminants from the skin and may alleviate itching and discomfort.  

2. Apply Antiseptic 

Treat the bitten site with an antiseptic lotion or ointment to stop infection and encourage recovery. Antiseptics that help disinfect the skin and lower the risk of bacterial infection include hydrogen peroxide and rubbing alcohol.

3. Avoid Scratching 

While it may be tempting to scratch the bite, avoid scratching as much as possible. Scratching can damage the skin, increase the risk of infection, and prolong healing time. Instead, try using a cold compress or soothing anti-itch cream to alleviate itching. 

4. Monitor Symptoms 

Watch for any symptoms of dengue fever, which typically develops within 4 to 10 days of being bitten by an infected mosquito. These symptoms may include severe headache, high fever, pain behind the eyes, joint and muscle pain, nausea, vomiting, and a rash. If you experience any of these symptoms, seek medical attention promptly.  

5. Stay Hydrated 

Keep yourself hydrated. Consume plenty of fluids throughout the day, such as water, herbal teas to boost immunity and electrolyte-rich drinks to stay hydrated and help your body fight off potential infections. Dengue fever can cause dehydration due to fever and vomiting, so it's essential to replenish lost fluids. 

6. Rest 

Get ample rest to help your body recover and take immune system boosting foods and drinks. Avoid strenuous activities that could exacerbate symptoms and prolong recovery time.  

7. Seek Medical Attention 

Seek the right medical assistance once you encounter any complications, like severe pain or bleeding, or if you start to exhibit symptoms of dengue fever. For dengue fever to be managed and complications to occur, early diagnosis and treatment are essential.
