Firstly, we proved the existence and uniqueness of the overall positive solution of the model. Secondly, by constructing a Lyapunov function, we obtained sufficient conditions for the existence and uniqueness of the ergodic stationary distribution of the positive solution of the model. Then, it was proved that infectious diseases would become extinct under certain conditions. Finally, this article verified the theoretical analysis results by numerically simulating the process of infectious diseases from outbreak to extinction, the numerical simulation results are symmetrical with the theoretical analysis.<\/jats:p>","DOI":"10.3390\/sym17020155","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T11:47:32Z","timestamp":1737460052000},"page":"155","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dynamics of Nonlinear Stochastic SEIR Infectious Disease Model with Isolation and Latency Period"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-7165-1042","authenticated-orcid":false,"given":"Wenbin","family":"Xu","sequence":"first","affiliation":[{"name":"School of Mathematics and Statistics, Xinyang College, Xinyang 464000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helong","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mathematics and Statistics, Xinyang College, Xinyang 464000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chuangliang","family":"Qin","sequence":"additional","affiliation":[{"name":"School of Mathematics and Statistics, Xinyang College, Xinyang 464000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"240","DOI":"10.1007\/s002850050051","article-title":"Analysis of an SEIRS epidemic model with two delays","volume":"35","author":"Cooke","year":"1996","journal-title":"J.
