The Wolbachia method involves introducing the naturally occurring bacteria Wolbachia into mosquito populations, particularly Aedes aegypti, which transmit diseases like dengue, Zika, chikungunya, and yellow fever. Wolbachia can prevent these viruses from replicating effectively inside the mosquito, thereby reducing the mosquito's ability to transmit the disease to humans. It can also affect mosquito reproduction, potentially suppressing populations over time.
