We introduce a basic reproduction number [Formula: see text] and establish threshold-type results on the global dynamics in terms of [Formula: see text]. In particular, we design the optimal control zone by investigating the influence of the starting point and length of the control zone in a one-dimensional bounded habitat on disease transmission. We also study the asymptotic distribution of the endemic steady state when the diffusion rates of the population are sufficiently small or large. Our analytical results show that the introduction of control zones tends to suppress the persistence of the disease to some extent and that the restriction of the movement of a population yields to the extinction of the disease at least in low-risk areas.<\/jats:p>","DOI":"10.1137\/24m1652374","type":"journal-article","created":{"date-parts":[[2024,12,12]],"date-time":"2024-12-12T04:01:16Z","timestamp":1733976076000},"page":"2569-2589","source":"Crossref","is-referenced-by-count":10,"title":["Dynamics of a Reaction-Diffusion SIS Epidemic Model with a Control Zone"],"prefix":"10.1137","volume":"84","author":[{"given":"Yaru","family":"Hu","sequence":"first","affiliation":[{"name":"School of Mathematical Sciences, Harbin Normal University, Harbin 150025, People\u2019s Republic of China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Jin","sequence":"additional","affiliation":[{"name":"Department of Mathematics, University of Nebraska-Lincoln, Lincoln, NE 68588 USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0103-163X","authenticated-orcid":true,"given":"Jinfeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Corresponding author.
