Overview
Situation: Influenza A(H7N9) virus with pandemic potential.
Country: China; three human cases originated in China and were reported in Malaysia (1) and Canada (2).
Number of human cases: 1349 confirmed; 497 deaths (since February 2013)
Provinces/municipalities: Beijing, Chongqing, Shanghai and Tianjin municipalities; Anhui, Fujian, Guangdong, Guizhou, Hebei, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Jilin, Liaoning, Qinghai, Shandong, Sichuan, Taiwan, Yunnan and Zhejiang Provinces of China; Hong Kong SAR; Macao SAR, Guangxi, Ningxia Hui and Xinjiang Uyghur Autonomous Regions; Sabah (Malaysia); British Columbia (Canada).
Animal/environmental findings: around 2,500 virological samplesfrom the environment, chickens, pigeons, ducks and a tree sparrow tested positive; positives mainly from live bird markets, vendors and some commercial or breeding farms.
Highly pathogenic virus findings: Out of the 1292 confirmed human cases, H7N9 virus isolates from three cases (two from Guangdong and one from Taiwan Provinces) were found to be highly pathogenic for chickens. In addition, the H7N9 highly pathogenic avian influenza virus was detected in 16 chicken and 6 environmental samples from Guangdong Province.
Note:The United States Department of Agriculture (USDA) National Veterinary Services Laboratories (NVSL) have confirmed a H7N9 highly pathogenic (Tennessee), and a H7N9 low pathogenic avian influenza virus (Tennessee, Alabama, Kentucky). Sequencing of the genome confirmed that they are of North American wild bird lineage origin. These viruses are thus not the same as the ones currently circulating in China. [reference1, reference 2, reference 3, reference 4, reference 5]
FAO actions: liaise with China and partners, monitor situation, monitor virus evolution, conduct market chain analysis, risk assessment, surveillance guidance and communication.
