Zhejiang province: a 35-year-old man in Shaoxin County was diagnosed with H7N9 avian influenza and is in serious condition. This is the first human case reported since 10 August 2013. Diagnosis and virus characteristics . Study of H7N9 genetic diversity increases as more sequences become public. A recent study showed: i) H7N9 viruses exhibit diverse genotypes; ii) the first reassortment likely occurred in wild birds and second in domestic birds; and iii) more than one H9N2 virus was involved in the creation of H7N9. Despite its diversity, H7N9 can still be detected by the current, validated diagnostic reagents. New isolates have been submitted to GISAID and GenBank / OpenFlu database: Host GISAID GenBank / OpenFluDB Chicken 34 25 Duck 2 2 Environment 15 14 Human 57 35 Pigeon 5 3 Total 113 79 Page 1 of 2; FAO/EMPRES H7N9 update Disclaimer: Information provided herein is current as of the date of issue. 15 October 2013 FAO cannot guarantee accuracy of information from reported sources. ** NOT FOR GENERAL DISTRIBUTION ** . Initial experiments at SERPL show existing, inactivated vaccines and available seed strains can reduce virus shedding in vaccinated chickens. The homologous Chinese H7N9 virus is still the most effective at reducing shedding. FAO actions . FAO continues supporting a-risk countries with surveillance and preparedness for H7N9 incursion. FAO assistance funded by USAID has supported the collection and analysis of nearly 10 000 bird and environmental swabs in South and Southeast Asia. No samples have tested positive. USAID continues supporting FAO activities in surveillance and preparedness, including compensation. FAO is finalizing H7N9 surveillance and sampling schemes for South and Southeast Asia. FAO launched TCP projects for SAARC and ASEAN regions at a participatory workshop on 18-20 September 2013: http://www.fao.org/asiapacific/rap/home/news/detail/en/?news_uid=197054 . FAO organized a USAID technical and policy meeting in Rome, 12–13 September 2013. On 26 April FAO called for USD 35 million to support the new global framework on H7N9.
