Umoya ngumthombo wokusasazeka kwezifo ezininzi.Ukuhanjiswa kwe-Airborne kubonakala ngokusasazeka ngokukhawuleza, ukugubungela ngokubanzi, ubunzima bokulawula, kunye nemiphumo emibi.Ngokukodwa, i-SARS kunye nezinye izifo ezosulelayo zokuphefumla ziyaqhubeka nokuvela, kwaye umba wokubulala iintsholongwane emoyeni kunye nokucocwa uye waba yingxaki yezempilo yoluntu.Uphononongo lubonise ukuba intsholongwane yekholera, intsholongwane yomkhuhlane, i-coronavirus, iClostridium difficile, i-VRE, i-MRSA, i-norovirus, kunye nokungunda inokuphila phezu kwezinto ezingaphiliyo kwaye ibe yimithombo eyosulelayo ekhokelela kusulelo.I-vre kunye ne-MRSA inokuphila kumphezulu wezinto iintsuku ukuya kwiiveki.Malunga ne-20-40% yosulelo lwentsholongwane lubangelwa kukudibana ngqo nesandla okanye ukudibana okungathanga ngqo nemiphezulu yezinto ezosulelwe yintsholongwane.
Olunye uphononongo lubonise ukuba ukucoceka kwezinto ezisingqongileyo kunye nokubulala iintsholongwane kumphezulu wezinto kunokulawula ngempumelelo ukusasazeka kwezifo ezosulelayo.Okokuqala, ukubulawa kweentsholongwane kumphezulu wento kunokunciphisa amanqanaba omthwalo we-pathogenic microbial kwaye inokubulala okanye isuse iintsholongwane ezingcolisekileyo ze-pathogenic microorganisms kunye ne-anti-drug resistant bacteria.Okwesibini, ukukhutshwa kwe-disinfection kwimigangatho yezinto kunokuphazamisa ukusasazeka kwe-pathogenic microorganisms.
