We consider a delayed susceptible-infected-recovered epidemic model on an uncorrelated complex network and address the effect of time lag on the shape and multiple waves of epidemic curves. We show that when the transmission rate is above a threshold, a large delay can cause multiple waves with larger amplitudes in the second and subsequent waves.
我们考虑一个在不相关复杂网络上的延迟易感-感染-恢复流行病模型，并探讨时间滞后对疫情曲线形状和多波现象的影响。我们表明，当传播率高于阈值时，较大的延迟会导致在第二波及后续波中出现振幅更大的多波现象。
