The research is aimed at studying these factors\u2019 influence on the predator\u2013prey system\u2019s dynamic behavior in the presence of infectious diseases. The system\u2019s solution properties and limitations were studied. All the necessary conditions for the system\u2019s stability locally and globally are calculated using various mathematical methods. The possibility of local bifurcation in the system has been studied. Finally, the system was solved numerically to confirm the results and understand the effect of changing parameter values on dynamic behavior. It has been found that, up to a critical value, the system is stabilized by the fear of susceptible predators; beyond that, predator extinction threatens the system. A similar observation has been made regarding the refuge rate. Nonetheless, the system dynamics are destabilized by the fear of the infected predators.<\/jats:p>","DOI":"10.1155\/jama\/8120929","type":"journal-article","created":{"date-parts":[[2025,3,31]],"date-time":"2025-03-31T09:52:07Z","timestamp":1743414727000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The Effect of Fear and Refuge on the Dynamics of a Predator\u2013Prey Model Incorporating Disease in Predator"],"prefix":"10.1155","volume":"2025","author":[{"given":"Roaa Hatem","family":"Talib","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1063-9775","authenticated-orcid":false,"given":"Raid Kamel","family":"Naji","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,3,31]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-662-08539-4"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1142\/2284"},{"key":"e_1_2_12_3_2","volume-title":"The Mathematical Theory of Infectious Diseases and Its Applications","author":"Bailey N.
