The latest case is a 64-year-old man, and brings the total of confirmed human H7N9 cases to 348.
"Locally, enhanced disease surveillance, port health measures and health education against avian influenza are ongoing," a spokesman for the DH said. "We will remain vigilant and maintain liaison with the World Health Organization and relevant health authorities. Local surveillance activities will be modified upon the WHO's recommendations."
As of Monday, 135 cases have been confirmed in Zhejiang, which has seen the majority of cases. Hunan has confirmed 13 cases.
"In view of human cases of avian influenza A(H7N9) confirmed in Hong Kong and multiple cases notified by the Mainland, the activity of the virus is expected to be higher in the winter season," the DH spokesman said. "Those planning to travel outside Hong Kong should maintain good personal, environmental and food hygiene at all times."
The department said boundary control points have been established for prevention and control of the illness. Travelers in the area are encouraged to wear masks and seek immediate medical attention if they experience symptoms.
