With the weather suppressing much of the mosquito population, health experts are turning their attention to learning lessons from one of the deadliest West Nile outbreaks in U.S. History.

State records show that here in Brazos County 8 people were diagnosed with the disease, and health experts say that number is much lower than the number of expected cases.

Federal authorities are collecting data and examining factors for the mosquito-borne illness that killed more than 240 in the U.S. About a third of them are from in Texas.

Dallas County, the epicenter of the outbreak, has begun year-round mosquito surveillance and testing.

What remains unclear is whether experts will be able to shed light on what caused it, why parts of Texas were so severely affected and if the next major surge can be forecast.
