A
It is an RNA virus with NA and HA surface proteins
2
Q
Understand vaccine development
A
Look at the strains that have been present in opposite hemisphere
3
Q
What is gene swapping?
A
When there is gene exchange between two lineages –> could increase virulence
4
Q
Does horizontal transmission favor higher or lower virulence?
A
Horizontal transmission favors higher virulence, carried through vectors.
5
Q
Does vertical transmission favor higher or lower virulence?
A
Vertical transmission favors lower virulence.
