Experimental data from in vitro cultures of main individual cells and ex vivo cultures of individual respiratory tissue suggest that viral tropism and replication kinetics are similar for pandemic and seasonal H1N1 viruses.36 However, data from animal models suggest that the 2009 2009 H1N1 virus causes more severe illness and may be much less transmissible than seasonal influenza viruses.37,38 Our study shows that pandemic and seasonal influenza A viruses are associated with similar viral-load dynamics, severity of clinical illness, and transmissibility.
