Two more cases of avian flu H7N9 in China

Although 2 more cases of the avian flu strain H7N9 bring the total number to 504 cases since the virus was first identified in 2013, there are still no signs that this strain is easily transmitted from person to person. However, there are some suggestions that there are many undetected and unreported mild cases of this type of flu. The high mortality attributed to this virus (approximately 35 percent) is based on the number of deaths among persons hospitalized with severe symptoms. Slightly more than half the cases have occurred in 4 principal provinces, Zhejiang, Guangdong, Jiangsu, and Shanghai.

In order to minimize any possible risk of acquiring this virus and other avian influenza viruses, visitors to China should avoid trips to live poultry markets.
