Background:　Coronavirus　disease　2019　(COVID-19)　is　primarily　a　respiratory　disease　that　has　become　a　global　pandemic.　Close　contact　plays　an　important　role　in　infection　spread,　while　fomite　may　also　be　a　possible　transmission　route.　Research　during　the　COVID-19　pandemic　has　identified　long-range　airborne　transmission　as　one　of　the　important　transmission　routes　although　lack　solid　evidence.　Methods:　We　examined　video　data　related　to　a　restaurant　associated　COVID-19　outbreak　in　Guangzhou.　We　observed　more　than　40,000　surface　touches　and　13,00　0　episodes　of　close　contacts　in　the　restaurant　during　the　entire　lunch　duration.　These　data　allowed　us　to　analyse　infection　risk　via　both　the　fomite　and　close　contact　routes.　Results:　There　is　no　significant　correlation　between　the　infection　risk　via　both　fomite　and　close　contact　routes　among　those　who　were　not　family　members　of　the　index　case.　We　can　thus　rule　out　virus　transmission　via　fomite　contact　and　interpersonal　close　contact　routes　in　the　Guangzhou　restaurant　outbreak.　The　absence　of　a　fomite　route　agrees　with　the　COVID-19　literature.　Conclusions:　These　results　provide　indirect　evidence　for　the　long-range　airborne　route　dominating　SARSCoV-2　transmission　in　the　restaurant.　We　note　that　the　restaurant　was　poorly　ventilated,　allowing　for　increasing　airborne　SARS-CoV-2　concentration.　(C)　2021　The　British　Infection　Association.　Published　by　Elsevier　Ltd.　All　rights　reserved.
