In this study, we are interested in the endemic of influenza
virus in Thailand. Numerical solutions are presented
comparing used the real data from 1997 to 2013. The values of
certain parameters of the model such as the birth rate, the
death rate and the total of human population, were obtained
from the demographic data of Thailand. They are μ =1/ 70
per year, which corresponding to a life expectancy of 70 years;
N = 62,644,913 , φ = 0.5and δ = 0.75 [25]-[26].
