The 30-year-old swine flu victim who was transferred from West Georgia Medical Center to Emory Hospital in Atlanta is worse off than most other flu patients.

Dr. Behzad Razavi, an infectious disease specialist at West Georgia Medical Center, told the Atlanta Journal-Constitution that the Kentucky woman has developed pneumonia, but her condition is not deteriorating.

He said she was transferred Thursday afternoon to take advantage of infectious disease experts at Emory.

Razavi told the Atlanta paper that doctors haven’t learned why her condition is more serious than others. Most flu victims recover within a few days without the need for a hospital stay.

The unidentified woman was the state’s first confirmed case of the swine flu. She had traveled to Mexico before returning home to Bowling Green, Ky., then traveling to LaGrange to attend a wedding.

At West Georgia, the woman was isolated in the intensive-care unit and the room was cleared of any airborne pathogens. Caregivers wore masks, gloves and gowns.

Holly Korschun, a spokeswoman for Emory University, said the woman was in critical condition Friday.

The woman’s swine flu case has been attributed to her home state.

Meanwhile, state health officials say a new swine flu case has been confirmed in Georgia, bringing the number of patients in the state to four.

Dr. Elizabeth Ford, head of the state Division of Public Health, said the Centers for Disease Control and Prevention confirmed Friday that a 13-year-old boy from Henry County tested positive for the H1N1 virus. They said his symptoms were mild and he did not require hospitalization.
