Umoya uyi-vector yokusabalalisa izifo eziningi.Ukudluliswa kwezindiza kubonakala ngokusabalala okusheshayo, ukusabalala okubanzi, ubunzima bokulawula, nemiphumela emibi.Ikakhulukazi, i-SARS kanye nezinye izifo ezithathelwanayo zokuphefumula komoya ziyaqhubeka nokuvela, futhi udaba lokubulala amagciwane komoya kanye nokuhlanzwa sekuyinkinga evelele yezempilo yomphakathi.Ucwaningo luye lwabonisa ukuthi igciwane lekholera, igciwane lomkhuhlane, i-coronavirus, i-Clostridium difficile, i-VRE, i-MRSA, i-norovirus, kanye nesikhunta singaphila phezu kwezinto ezingaphili futhi zibe imithombo ethathelwanayo eholela ekuthelelekeni.I-vre ne-MRSA ingaphila phezu kwezinto izinsuku ukuya emavikini.Cishe u-20-40% wokudluliselwa kwegciwane kungenxa yokuthintana ngesandla okuqondile noma ukuthintana okungaqondile nezinto ezingenwe yigciwane.
Olunye ucwaningo lubonise ukuthi ukuhlanzeka kwendawo ezungezile kanye nokubulala amagciwane endaweni ethile kungalawula ngempumelelo ukusabalala kwezifo ezithathelwanayo.Okokuqala, ukubulawa kwamagciwane endaweni yento kunganciphisa amazinga omthwalo we-pathogenic microbial futhi kungabulala noma kususe amagciwane angcolile e-pathogenic kanye namagciwane amelana nezidakamizwa eziningi.Okwesibili, ukukhishwa kwe-disinfection kwezindawo ezingaphezulu kungaphazamisa ukusabalala kwama-microorganisms e-pathogenic.
