Therefore, the characteristics of influenza also highlight its “epidemic,” with a sudden onset, spread rapidly, broad coverage of the characteristics, and the general population susceptibility. Today’s traffic is more likely to cause a pandemic. The annual distribution of common cold, healthy adults every year
