BACKGROUND The immunoneuroendocrine axis plays a major role in the regulation of the host's response to infection, but its role in severe H7N9 pneumonia is still unknown. Therefore, this study is carried out to explore the relationship between the immunoneuroendocrine axis and severe H7N9 pneumonia. CASE PRESENTANTION The study included two H7N9 pneumonia patients. Endocrine response and cell...
Letters Virus-host interactions and the unusual age and sex distribution of human cases of influenza A(H7N9) in China, April 2013 Over the past two weeks, Eurosurveillance has published several timely papers related to the emergence of a new influenza A(H7N9) virus affecting humans in China [1-3]. Genetic studies by Kageyama et al. [1] and Jongens et al. [2] assessed evidence in the genome for ...
waves have been detected in China. Live poultry market (LPMs) exposure is regarded as a major risk of H7N9 virus infection. However, despite strict interventions implemented in the epicenter cities during each outbreak, reports indicate a gradual nationwide spread of the virus. In this study, the impact of LPMs interventions in virus persistence and transmission in the province of Guangdong, th...
Among all influenza viruses assessed using CDC's Influenza Risk Assessment Tool (IRAT), the Asian lineage avian influenza A(H7N9) virus (Asian H7N9), first reported in China in March 2013,* is ranked as the influenza virus with the highest potential pandemic risk (1). During October 1, 2016-August 7, 2017, the National Health and Family Planning Commission of China; CDC, Taiwan; the Hong Kong C...
OBJECTIVE A total of 131 cases of avian-originated H7N9 infection have been confirmed in China mainland from February 2013 to May 2013. We calculated the overall burden of H7N9 cases in China as of 31 May 2013 to provide an example of comprehensive burden of disease in the 21st century from an acute animal-borne emerging infectious disease. DESIGN We present an accurate and operable method fo...
The advent of a novel avian origin H7N9 emerged in China in March 2013 is of major health concern, as it has little virulence in birds but can cause severe illness and death in humans. As people continue to get infected by this new virus in 2014, we need to understand the current status and trend of its evolution at the end of year 2014. The influenza viruses have two surface proteins, haemaggl...
Avian influenza A(H7N9) virus infections frequently lead to acute respiratory distress syndrome and death in humans. We aimed to investigate whether primary cultures of human respiratory tract epithelial cells are helpful to understand H7N9 virus pathogenesis and tissue tropism, and to evaluate how patient-related characteristics can affect the host's response to infection. Normal human bronchi...
Avian influenza A/H7N9 virus infection causes pneumonia in humans with a high case fatality rate. However, virus-induced modulation of immune responses is being recognized increasingly as a factor in the pathogenesis of this disease. In this study, we compared the pathogenicity of A/H7N9 infection in BALB/c and C57BL/6 mouse models, and investigated the putative involvement of proinflammatory c...
Nepal boarders India and China and all three countries lie within the Central Asian Flyway for migratory birds. Novel influenza A H7N9 caused human fatalities in China in 2013. Subclinical infections of influenza A H7N9 in birds and the potential for virus dispersal by migratory birds prompted this study to assess avian H7N9 viral intrusion into Nepal. Surveillance of influenza A virus in migra...
Since the first outbreak of avian influenza A(H7N9) virus in humans was identified in 2013, there have been five seasonal epidemics observed in China. An earlier start and a steep increase in the number of humans infected with H7N9 virus was observed between September and December 2016, raising great public concern in domestic and international societies. The epidemiological characteristics of ...
