A notable characteristic of La Crosse Encephalitis is that the mosquito remains infected for how long?

Explanation:
When a mosquito picks up La Crosse encephalitis virus, the virus replicates and moves to the salivary glands. From there, the mosquito remains capable of transmitting the virus with every bite for the rest of its life because the infection persists and is not cleared by the mosquito. This lifelong infectiousness means an infected mosquito can contribute to transmission across many feeding cycles, which is why this trait is a notable characteristic. The other timeframes imply only a short window of transmission, but for this virus in the mosquito, the infectious state lasts for the mosquito’s entire life.
