am indeed still working in this area! the clade currently circulating globally (minus australia) is 2.3.4.4b, there are a few extant clades other than that but theyre localised (e.g. some 2.3.2.1 decendents in south east Asia, Bangladesh and India), maybe some 2.3.4.4 cousins in China still as well?

If you'd like to celebrate the biology of viruses - or the fight against viral diseases - this winter, try out our free and updated #VirusSnowflake designs.
Please share, and if you have any photos of Virus Snowflakes in your area it would be lovely to see them!

from a wildlife perspective its incredibly difficult to put the genie back in the bottle, but from a poultry perspective this work might help inform seasonal biosecurity recommendations - e.g. coastal farms need to consider minimising exposure to gulls in spring/summer due to risk of H5N1?
