A resident of Alberta Canada has just died after being infected with H5N1 after visiting Beijing China [hat-tip, NawtyBits].
Date of symptom onset: December 27, 2014
Date of hospitalisation: January 1, 2014
Date of death – January 3, 2014
The person who died first reported symptoms while on Air Canada flight 030 from Beijing to Vancouver on December 27, 2013.
This person presented with unusual neurological symptoms rather than the typical respiratory signs.
There have been no reports of H5N1 in Beijing nor any explanation of how the visitor from Canada was infected.
The odds that one visitor from another country was infected as a result of environmental exposure in China but that no one in China has been infected by the same source are vanishingly low.
As Dr. Niman has pointed out, it is odd that H5N1 cases are being missed in China given the intense scrutiny influenza patients are receiving due to the ongoing reports of H7N9 infections.
As Pixie has pointed out, there is a curious lack of urgency or concern on the part of Chinese officials to uncover how this visitor from Canada was infected, presumably in Beijing. In fact, in this Xinhua story, there is no indication that Chinese officials are attempting to find the source of the infection. This is odd.
So, how did the visitor from Canada get infected with H5N1 in China? At this point, all we can say is that the source is hidden.
