Brazil's Mosquito Factory Fights Dengue with Wolbachia Bacteria

World's Largest Mosquito Biofactory

• 💡 Brazil has opened the world's largest biofactory in Kurachiba, aiming to produce 100 million mosquito eggs weekly.
• 🦠 These eggs are infected with the Wolbachia bacteria, which prevents Aedes aegypti mosquitoes from transmitting dengue.

Dengue Fever Prevention Strategy

• 🎯 The strategy involves releasing Wolbachia-infected mosquitoes to spread the bacteria among wild mosquito populations.
• 🦟 This method aims to protect approximately 140 million people from dengue, a disease that infects hundreds of millions globally each year.

Global Successes and Brazilian Impact

• 🇦🇺 In Australia, over 12 years of using this method resulted in no local dengue virus circulation, only imported cases.
• 🇮🇩 A study in Indonesia showed a 77% reduction in dengue cases.
• 🇧🇷 In Brazil, the city of Niteroi reported an 89% reduction in dengue cases after initial releases.

Addressing Dengue Hotspots in Brazil

• ⚠️ In 2024, Brazil recorded its worst year for dengue, with nearly 6.3 million people infected.
• 📍 The operations team is prioritizing the release of these new mosquitoes into the worst-hit areas to reduce dengue hotspots.
