Methods, To the authors’ knowledge, no sufficient/obvious data exist on lateral routes of disease transmission through respiratory droplets along the x-axis. The present study establishes a preliminary baseline approach based on the upper pharynx-mouth geometry for lateral social distancing to protect susceptible persons from the droplets of an infected person. An enhanced version of ART (Aydin’s Research Team) model has been employed as a supplementary tool of Stokes’s law for quantification of motion dynamics of the virus/bacterium-laden droplets in public indoor places. Results, A range of droplet diameters varying from 1 μm to 2000 μm were considered in this study. The droplets with a diameter of ≤ 22.5 μm can completely evaporate during settling and droplet nuclei can remain in the air for extended periods. An individual Influenza virus can stay airborne for 34.4 days, while a single Streptococcus bacterium remains suspended for 18.6 hours. The proper social distancing between infected and healthy persons should be about 2.9 and 0.9 m longitudinally, and 0.45 and 0.15 m laterally based on the novel aspects of the present study for sneezing/coughing and breathing/talking, respectively. The trajectory of respiratory particles in the streamwise and radial directions resembles the shape of a truncated cone due to the upper pharynx-mouth relationship. Conclusion, The outcomes of this study can help further understanding of respiratory particle trajectory, thereby improving measures to mitigate disease transmission.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-09-04"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2025-08-22"}],"filename":"yam68(3)_197.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","license_note":"© 2025 Tottori University Medical Press","licensetype":"license_note","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://repository.lib.tottori-u.ac.jp/record/2001979/files/yam68(3)_197.pdf"},"version_id":"b6d0c8b8-bb49-4e69-b1d8-44acdb86d724"}]},"item_30002_heading36":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"Original Article","subitem_heading_language":"en"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Tottori University Medical Press","subitem_publisher_language":"en"}]},"item_30002_relation18":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.33160/yam.2025.08.004","subitem_relation_type_select":"DOI"}},{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.lib.tottori-u.ac.jp/yam/yam/yam68-3/68-3contents.html","subitem_relation_type_select":"URI"}}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_rights6":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"© 2025 Tottori University Medical Press","subitem_rights_language":"en"}]},"item_30002_source_identifier22":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"13468049","subitem_source_identifier_type":"EISSN"}]},"item_30002_subject8":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"droplet evaporation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"indoor environment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lateral trajectory","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microbial spread","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Stokes and ART models","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A New Approach for Respiratory Droplet Trajectory : Implications for Viral and Bacterial Disease Transmission in Emergency Departments","subitem_title_language":"en"}]},"item_30002_version_type15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"A New Approach for Respiratory Droplet Trajectory : Implications for Viral and Bacterial Disease Transmission in Emergency Departments","item_type_id":"30002","owner":"10","path":["9","12","1759291552751"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-09-04"},"publish_date":"2025-09-04","publish_status":"0","recid":"2001979","relation_version_is_last":true,"title":["A New Approach for Respiratory Droplet Trajectory : Implications for Viral and Bacterial Disease Transmission in Emergency Departments"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-10-01T08:11:15.666266+00:00"}
