The Journal Nature notes that H7N9 bird flu poised to spread in new article
An excellent article appeared in the Journal Nature noting that virus continues to expand its geographical range now moving into Beijing in the north and Henan in the center of the country. Experts worry that this new development may be the start of an expansion that may see H7N9 quickly fan out across large areas of China, and beyond.
The article notes the key distinguishing issues between H7N9 and its other flu relatives:
- Genetic analyses of the new virus show that it has several mutations making it more adapted to humans than is H5N1.
- Does not cause serious illness in poultry and other birds so there is no advance notice that the illness has moved into a flock of birds.
- The poultry trade may be effectively and silently moving the virus around the country and even the region.
