Texas West Nile fever cases and deaths have more than doubled over the past two weeks. If you need a medical expert, Dr. Jeff Kalina is associate director of emergency medicine at The Methodist Hospital in Houston, Texas.

He and the Methodist ER team are being more vigilant about possible West Nile cases coming through our ER and suspects he's seen 6-7 cases.
