The latest case of bird flu in China, which appears to be related to a substrain of the H10N8 virus, is already displaying some worrying characteristics, an expert in infectious diseases has said.
Dr Jeremy Farrar, director of the Wellcome Trust, told BBC News:
We should always be worried when viruses cross the species barrier from birds or animals to humans as it is very unlikely that we will have prior immunity to protect us.
We should be especially worried when those viruses show characteristics that suggest they have the capacity to replicate easily or to be virulent or resistant to drugs. This virus ticks several of these boxes and therefore is a cause for concern.
