Kakaretso ena e felletseng ea litlhahlobo e fana ka bopaki bo teng mabapi le tšusumetso eo lits'ebetso tsa HVAC li nang le tsona phetisong ea vaerase e tsamaisoang ke moea.Tlhahlobo ea pele e hatisitsoeng ka 2007 e fumane kamano e hlakileng pakeng tsa moea le litekanyetso tsa tšoaetso ea kokoana-hloko mehahong.Ho fihlela sena, bo-rasaense ba hlokometse hore phetoho ea tuberculin e ne e amahanngoa haholo le litekanyetso tsa moea tse ka tlaase ho 2 liphetoho tsa moea ka hora (ACH) ka likamoreng tsa mokuli ka kakaretso 'me li batla hore ho etsoe lipatlisiso tse eketsehileng ho lekanya litekanyetso tse fokolang tsa moea maemong a kliniki le ao e seng a kliniki.
Phuputso ea bobeli e phatlalalitsoe ka 2016 e fumaneng liqeto tse tšoanang tsa hore ho bonahala ho na le kamano lipakeng tsa likarolo tsa moea le phetisetso ea vaerase e tsamaisoang ke moea.Phuputso ena e boetse e totobalitse tlhokahalo ea lithuto tsa mafu a mangata tse entsoeng hantle tse hlophisitsoeng hantle.
Haufinyane tjena, maemong a koluoa ea COVID-19, bo-ramahlale ba hlahlobile lits'ebetso tsa HVAC le karolo ea bona phetisong ea li-coronavirus.Ba fumane bopaki bo lekaneng bo tšehetsang kamano lipakeng tsa SARS-CoV-1 le Middle East Respiratory Syndrome coronavirus (MERS-CoV).Leha ho le joalo, bakeng sa SARS-CoV-2, bopaki bo ne bo sa phethehe.
