Monday Micro – Influ-Venn-Za!

By Siouxsie Wiles 15/04/2013

A new strain of bird flu (H7N9*) has appeared in China. Since the first report two weeks ago, 51 people are known to have been infected of which 11 have died. Transmission seems to be from close contact with poultry and many birds are being culled as a precaution. Cases started in Shanghai and the eastern provinces of Jiangsu and Zhejiang but have now been reported in Beijing.

For those struggling to tell their H7N9 from their H5N1, the lovely peeps who run Information is Beautiful have come up with a handy guide to flu in the form of a beautiful Venn diagram:

Influenza types


*Flu viruses are classified into subtypes based on antibody responses to the two large glycoproteins on the outside of the viral particles, hemagglutinin and neuraminidase.
