A virus emerging before our eyes 

When I wrote about the high incidence of norovirus infections in the UK recently – http://goo.gl/TUdko – a commenter helpfully pointed to a paper published in Eurosurveillance on January 3 described a new variant of norovirus called Sydney 2012.
The UK HPA has now responded to this and says:
“Testing carried out when cases started to rise in October revealed a cocktail of different strains that were circulating including Sydney 2012 and another called New Orleans 2009, although no one strain was dominant. The latest testing of the most recent outbreaks, completed this week, has now shown that Sydney 2012 has overtaken all others to become the dominant strain.” http://goo.gl/dkxvb

The advice remains the same – wash your hands!
