New H7N9 cases

The Center for Infectious Disease Research and Policy (CIDRAP) reports that eight latest H7N9 cases from China noted last week (2 June) in a regular update from Hong Kong's Centre for Health Protection (CHP) are down slightly from nine cases reported last week. Among the new batch of illnesses, six patients had known exposure to poultry, poultry markets, or mobile stalls. No deaths were reported.

All of the sick people are adults with illness onsets ranging from 12 May to 29 May, and five are men.

The patients are from seven different provinces that make up a broad geographic area, which with late-season northward spread has been a unique feature of China's fifth and biggest wave of H7N9 activity, which began in October and is still under way. Affected provinces are Shandong, Anhui, Guangxi, Hebei, Hubei, Shaanxi, and Sichuan.
