Clearing the fog: need for revised strategies against Aedes mosquitoes, Pg2

Key Highlights:

• Aedes-borne viral diseases (ABVD) like dengue, Zika, and chikungunya impact India's productivity.
• Outdoor fumigation is a common but ineffective method against Aedes mosquitoes.
• Personal protection using repellents and covering the body, along with community mobilization, are effective strategies.
• The "10 Weeks, 10 AM, 10 Minutes" campaign in Delhi promotes larval source reduction.
• DEET is a gold standard repellent, but education is needed to combat misinformation and increase its availability in India.

Detailed Insights:

• Aedes mosquitoes adapt to human settings, feeding indoors during the day and at night under artificial light, making methods like outdoor fumigation less effective.
• Effective personal protection includes using safe repellents like DEET, picaridin, PMD, IR3535, and 2-undecanone, and wearing clothing that covers the body from September to November.
• Community actions such as removing stagnant water from plant pots, cleaning water containers, and eliminating discarded plastic can significantly reduce larval breeding sites.
• Plastic pollution is directly linked to the risk of ABVD transmission, highlighting the importance of regular trash collection and flood management.
• Top-down initiatives like the use of Wolbachia mosquitoes and spatial emanators show promise but require further study, approval, and cost reduction for widespread adoption in India.

Key Concepts Involved:

• Aedes-borne Viral Diseases (ABVD): Diseases transmitted by Aedes mosquitoes, including dengue, Zika, and chikungunya.
• Larval Source Reduction: Eliminating mosquito breeding sites by removing stagnant water and cleaning containers.
• Wolbachia Mosquitoes: Mosquitoes infected with Wolbachia bacteria to suppress mosquito populations or prevent disease transmission.
