The evidence with HPAI H5N8 and H5N2 has been - that, despite being cousins to some pretty nasty H5 viruses (H5N1, H5N6) – neither has shown the ability to infect, or sicken, humans.
That said, we have seen some studies suggesting there may have been a few subclinical H5N2 human infections in Taiwan a few years back, and last spring Korea discovered a number of dogs with antibodies to H5N8.
But so far, no symptomatic human cases have been reported with either subtype
The concern of course is that influenza viruses are constantly changing, and so their observed behavior in the past is not guaranteed to hold true in the future.
Today Taiwan announced the detection of H5N8, along with a supposedly `never-seen-before’ strain of H5N2 (see Taiwan Reports H5N8 On Goose Farm and `New Strain’ Of H5N2), and since they are dealing with new (or relatively new) viral strains, an abundance of caution is warranted.
Taiwan’s CDC has issued a statement, as has the City of Taipai’s Health Department, urging people to exercise caution around live poultry, and advising anyone working with poultry who develops symptoms of influenza to immediately seek medical care.
These machine translations are a bit kludgy, but they leave no doubt that the local health departments are taking these outbreaks seriously.

But due to the discovery of H5N2 H5N8 for domestic first new strain, which occurred in January 2014 and 3 HA cut points and South Korea (birds, ducks and wild ducks) sequences of more than 96% Similarly, CDC Department of the future will also be conducted on relevant contacts seroepidemiological survey, conduct a follow-up investigation of the effects of the new virus.
According to the Council of agriculture issued H5N8 and H5N2 avian influenza viruses detected, in view of the two viruses are similar to January 2014 found virus in South Korea, are the highly pathogenic virus; Japan in April outbreak, China in October, Germany and the Netherlands and the United Kingdom in November also poultry disease is transmitted, in December, Italy, Russia, the United Kingdom and the United States have been found with the virus. The World Health Organization says, did not rule out are among the migratory birds spread the virus from Asia to Europe, and anticipation of future possible poultry outbreaks in more countries.
CDC also calls for, in the event of avian influenza outbreaks in poultry farms of relevant staff, during the self-health management, such as acute respiratory infection symptoms appear, should take the initiative to notify the local health board to assist medical care.
