Figure 1From: Hopf bifurcation analysis of a delayed SEIR epidemic model with infectious force in latent and infected periodThe profile solutions of delayed model (2.1) for \(\tau = 0, 5,15,25\). The parameter values used in Table 1 and \(\beta =2\) so that \(R_{0} < 1\). The initial conditions are \(S(0)=3.9327 \times 10^{5}\), \(E(0)=15\), \(I(0)=24\), and \(R(0)=2.0894\times 10^{5}\)Back to article page
