BEIJING - H7N9 bird flu has killed 19 in China this year already, and the total number of human infections has reached 96, according to the Chinese Center for Disease Control and Prevention.
Shu Yuelong, director of the Chinese National Influenza Center (CNIC), said on Monday that a large-scale H7N9 epidemic is unlikely during the Spring Festival holiday, as no H7N9 virus mutation that could affect public health has been identified so far.
"There is no evidence of constant inter-human transmission, and the risk assessment of H7N9 epidemic outbreak is unchanged," said Shu.
Shu reiterated that H7N9 is more prone to human infection than H5N1, with H7N9 case fatality rate reaching 20 to 30 percent.
The virus is more difficult to be prevented as there is no obvious symptom for H7N9 infected poultry, and at present the CNIC is not able to precisely predict the direction of the mutation of the H7N9 virus.
"We will continue to strengthen monitoring and carry out research," said Shu.
On Sunday, the National Health and Family Planning Commission issued a paper on H7N9 diagnosis and treatment, noting that early report, diagnosis and treatment are the best ways to prevent and control the virus.
