After establishing well-posedness of the model system, we identify the basic reproduction number <i>R</i><sub>0</sub> and explore the properties of <i>R</i><sub>0</sub> when the dispersal rate for infected target cells varies from zero to infinity. Moreover, we demonstrate that the basic reproduction number is a threshold parameter: the infection and virus will be cleared out if <i>R</i><sub>0</sub> ≤ 1, while if <i>R</i><sub>0</sub> &gt; 1, the infection will persist and the model system admits at least one positive (chronic infection) steady state. For the special case when all model parameters are spatial homogeneous, this chronic infection steady state is unique and globally asymptotically stable.","is_dataset_classified":null,"base_score":1.3862943611198906,"endowment":1.3862943611198906,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"32233555","pmcid":null,"openalex_id":"https://openalex.org/W3010582810","authors":[],"funders":[],"total_grants":0,"fwci":0.3538,"citation_percentile":0.64829837,"influential_citations":0,"citation_trend":[{"year":2022,"count":1},{"year":2023,"count":1},{"year":2025,"count":1}],"oa_status":"gold","license":"cc-by-nc-sa","oa_locations":[{"url":"https://doi.org/10.3934/mbe.2020141","host_type":"journal"},{"url":"https://doi.org/10.3934/mbe.2020141","host_type":"publisher"},{"url":"http://www.aimspress.com/article/10.3934/mbe.2020141/pdf","host_type":"publisher"},{"url":"https://pubmed.ncbi.nlm.nih.gov/32233555","host_type":"repository"},{"url":"https://doaj.org/article/b0344c69d6694e8aa5646fc264d866c9","host_type":"repository"}],"fields_of_study":["Mathematical and Theoretical Epidemiology and Ecology Models","Evolution and Genetic Dynamics","COVID-19 epidemiological studies"],"mesh_terms":["Humans","Models, Biological","Virus Diseases","HIV Infections","Basic Reproduction Number"],"keywords":["Basic reproduction number","Biological dispersal","Steady state (chemistry)","Chronic infection","Clearance","Homogeneous","Dynamics (music)","Biology","Viral infection","Mathematics","Virology","Statistical physics","Virus","Biological system","Physics","Immunology","Population","Immune system","Demography","Chemistry","Medicine","Spatial heterogeneity","Global stability"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Life in Land"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-30T02:20:29.566827Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
