HARRISBURG — Pennsylvania Lt. Gov. Catherine Baker Knoll said Wednesday that she has left the Baltimore hospital where she was receiving intensive treatment for cancer, although she now is also battling a viral infection.

The infection has slowed her recovery, but her condition is good and she continues to look forward to resuming her duties someday, Knoll said in a statement.

"I fully intend to return to my duties as lieutenant governor, but I don't have a timetable for that," she wrote.

Knoll contracted a viral infection as a result of chemotherapy treatments that weakened her immune system, according to her chief of staff, Salvatore M. Sirabella.

Since early October, Knoll has been in Johns Hopkins Kimmel Cancer Center, surrounded by family. She left the facility Tuesday, and has entered a physical therapy facility in the Washington, D.C., area to deal with the infection, Sirabella said.

Knoll, 78, was diagnosed with neuroendocrine cancer in July and has undergone radiation and chemotherapy treatments.
