Yesterday, the National Health and Family Planning Commission and WHO held a joint briefing of human infection with the H7N9 avian influenza. It was announced that based on available evidence, the risk of infection is mainly concentrated in the live bird markets. But China may have further sporadic cases, including expanding epidemic. And the possibility of human infection of the H7N9 bird flu in Ya’An area still exists where a recent Ms. 7.0 earthquake caused about 200 death and thousands of people injured.
Director of the WHO Influenza Melbourne Collaborating Centre, Anne Kelso said that the recent reduced increase of number of new cases in Shanghai has closed relationship with Shanghai government’s decision of closing the live stock market on April 6. With the coming of spring and temperature changes, there will be some changes in the epidemic reflecting the features and characteristics of the seasonal flu.
