McLennan County (January 3, 2013)- The number of flu cases surged in the month of December in McLennan County.
The flu season usually begins in the month of February.
"From one week to the next we saw it jump to 150 then to 200 cases," Kelly Craine, spokesperson for the McLennan County Public Health District said.
This time last year McLennan County saw 138 cases in the month of December.
Last month 573 cases were reported.
"The vast majority of patients I've seen with the flu haven't had their flu vaccination but I have seen some with flu vaccination that also have the flu," said Dr. David Meyers, Hillcrest Midway Clinic.
Doctors say the flu vaccine covers three strains of the flu virus.
The reason some people who are vaccinated are still getting the flu could be because there may be a strain that is not covered by the vaccine or the person may have a weakened immune system.
"I still strongly encourage people to get vaccinated.," Dr. Meyers said.
The Center for Disease Control and Prevention website lists ways to prevent the spread of the virus which include washing your hands, covering your mouth and nose when coughing or sneezing and limiting contact with other people if you do come down with the flu.
