H7N9 Background


New: The live data files for these graphics are now hosted on my GitHub repository: H7N9-Cases

Note that the 2013 numbers and details are collected from numerous sources and can't be considered reliable or complete. 2014 cases mainly come from WHO reports and are more consistent and complete with respect to onset dates and locations. Note however that 46 deaths were reported for 144 cases in 2013 and 72 deaths in January & February 2014 whereas these data report only 37 deaths over all. This is because this site can only show deaths that have been linked to known cases and many deaths are reported without that link.

Many thanks to Lu Lu at the Institute of Evolutionary Biology, University of Edinburgh for help compiling the initial list from Chinese media sources. More recently the WHO's Global Alert and Response, Disease Outbreak News pages have been reliably listing information on individual cases.
