H7N9 bird flu may have infected twice as many people as the 103 cases reported, an analysis by researchers at the University of Hong Kong showed.
There may be 90 to 120 ill adults who haven’t been detected because their infections are mild, Benjamin Cowling, associate professor at the university’s public health research center, said today. The researchers’ analysis suggests risk of serious illness from the virus rises substantially with age, with more than half of reported cases age 60 or older, he said.
