A Periodic Epidemic Model with Delay and Multiple Pathogens

摘要：

We study a periodic SIS epidemic model with time delay and multiple pathogen strains.By introducing the reproduction number of each strain, we establish the existence and stability of single strain periodic solution. It is also shown that coexistence can take place under certain conditions. This result extends and improves the result of 1. Numerical simulatins are given to demonstrate our theoretical results.
