Question 20

Your dog has flu caused by an H3N8 strain.Assume that you breathe in this strain,after you have already come in contact with an H1N1 strain.Both viruses go into the cells of your upper respiratory tract.During the viral replication cycle inside of your epithelial cells,genetic information for hemagglutinin antigen and for neuraminidase antigen are recombined.Your cells end up producing a new variant---H3N1.Predict what might happen as a result of this set of events.

A) Only people who have never had flu before will get sick from the new H3N1 variant. 
B) This is not a problem because the human immune system can respond quickly to any new antigens never seen before.

D) Since this new virus has antigens from a dog strain,the new strain will not be able to infection human cells.
