- 2. -3 types of Myxoviruses, Type A, B, and C antigenic types (Also 300 sub-types (recombinants))
- -Most flu viruses differ from cold viruses because they have spikes, Hemagglutinin (H,HA) and Neuraminidase (N,NA; breaks down neuraminic acid in animal membrane)
- 3. respiratory secretions (cough/sneeze) person to person or objects to person
- 4. 2-3 days
