In this Deep Dive, we look at the tiny but dangerous Aedes aegypti mosquito, carrier of dengue, Zika, and chikungunya. After the rains, even a teaspoon of standing water can become a breeding ground—from bottle caps to old tires. Baja’s health officials have cleared over 200,000 breeding sites and deployed thousands of traps, but lasting success depends on community action: lava, tapa, voltea y tira (wash, cover, turn over, throw away). Can individual vigilance truly keep the region safe, or will the bugs always find a way back? 🦟💧⚠️
