Abstract: An epidemic model with two parallel infectious stages and time delays and pulse vaccination is proposed. We introduce four thresholds and further obtain the conditions that the disease will be extinct or not. Corollaries show that under condition that θ>max{θ∗1,θ∗2} the disease will fade out, and if θKeywords: Parallel infectious stages; Time delay; Pulse vaccination; Stability; Permanence (search for similar items in EconPapers)
