Epidemiology of Human Infections with Avian Influenza A(H7N9) Virus in China [PDF]

New England Journal of Medicine, 2014
The first identified cases of avian influenza A(H7N9) virus infection in humans occurred in China during February and March 2013. We analyzed data obtained from field investigations to describe the epidemiologic characteristics of H7N9 cases in China identified as of December 1, 2013.Field investigations were conducted for each confirmed case of H7N9 ...

Evolution and Antigenic Differentiation of Avian Influenza A(H7N9) Virus, China. [PDF]

Emerg Infect Dis
We characterized the evolution and molecular characteristics of avian influenza A(H7N9) viruses isolated in China during 2021-2023. We systematically analyzed the 10-year evolution of the hemagglutinin gene to determine the evolutionary branch. Our results showed recent antigenic drift, providing crucial clues for updating the H7N9 vaccine and disease ...

Human infection with avian influenza A H7N9 virus: an assessment of clinical severity [PDF]

Lancet, The, 2013
Characterisation of the severity profile of human infections with influenza viruses of animal origin is a part of pandemic risk assessment, and an important part of the assessment of disease epidemiology. Our objective was to assess the clinical severity of human infections with avian influenza A H7N9 virus, which emerged in China in early 2013.We ...
