To　prevent　the　spread　of　coronavirus　disease　2019　(COVID-19),　stringent　quarantine　measures　have　been　implemented　so　that　healthy　people　and　virus　carriers　have　isolated　themselves　in　the　same　community　owing　to　the　limit　capacity　of　healthcare　facilities.　With　the　exponential　growth　of　the　infected　population,　the　residential　environment　is　contaminated　by　fomites　from　the　infected　residents　and　consequently　threating　the　health　of　susceptible　residents.　Till　now,　little　has　been　acknowledged　on　this　indirect　transmission　route　and　its　role　on　community　transmission.　Here　we　address　the　impact　of　self-isolated　virus　carriers　on　the　residential　environment　and　elucidate　the　potential　transmission　pathways　via　contaminated　environment　in　communities.　We　urge　further　investigation　on　the　superspreading　cases　in　communities　and　hope　to　arouse　the　attention　to　evaluate　the　potential　risk　of　indirect　transmission　route　as　well　as　the　corresponding　control　measures.
