MINNEAPOLIS — The number of new human H7N9 avian flu cases in China has increased sharply, with 16 reported, including 15 on the mainland — most of them in Guangdong province — and another imported infection reported by Hong Kong, according to the Center for Infectious Disease Research & Policy at the University of Minnesota.
China and Hong Kong have now reported 38 cases in the fifth wave of H7N9 activity, which began in October, far more than the 10 cases reported at this point in the season last year.
Increasing H7N9 activity comes amid the lead-up to the Lunar New Year. . .
