According to analysis by the Municipal Center for Disease Control and Prevention, it is unlikely that there will be a large number of local cases of H7N9 bird flu in Beijing. However, there may be cases of sporadic cases caused by private transactions of individual live birds, and a small amount of clustering may not be ruled out. In addition, Beijing has a large number of patients coming to Beijing for medical treatment. Therefore, the risk of imported cases remains high. (Source: Xinhua News Agency Author: Zhao Dandan)
