Flu season has arrived in Southwest Oklahoma.
Rena Evans, district nurse manager for the Comanche County Department of Health, said Friday the Southwest Region of the state is having a reasonably mild influenza year, compared to other parts of Oklahoma.
There has been only one hospitalization for the flu reported in Comanche County, according to the Oklahoma State Department of Health's website.
Evans said the Department of Health relies on a series of reporting sites across the state to keep track of flu infection and cases of flu-like symptoms. The baseline or normal level of reported cases in the general population is 3.5 percent.
She said Southwest Oklahoma Region 3 is below that number, but higher than last year, when the flu season was even milder. Region 3 had a reported rate of 2 percent last year at this time.
"We're a little more active this season so far," Evans said.
In comparison, the state of Oklahoma is sitting at just under 5 percent in the number of reported cases, she said.
Only one flu-related death has been reported in Oklahoma this season, a patient in Tulsa.
