Answer:
Of the mentioned statements, the incorrect one is option D.
Explanation:
The normal H5N1 strain or the bird flu virus when get attached with the alpha 2,3-sialic acid results in the infection of the lower respiratory tract in humans. The condition occurs very rarely. In comparison, the H1N1 or the human influenza strain gets attached with alpha-2,6 sialic acids and easily results in the infection of the upper and lower respiratory tract.
However, if the mutation takes place in the H5N1 strain, it can bind with the alpha-2,6 sialic acid and can result in the overall infection of the human respiratory tract. Now due to the occurrence of mutations in the H5N1 strain, bird flu can get transmit easily from birds to humans and from one human to another human. Also due to lack of immunity because of the emergence of new strain, the condition can become lethal as, like normal flu, the mutated strain can also result in the infection of the entire respiratory tract.
