Nk’uko ubushakashatsi bwasohotse mu gitabo Annals of Internal Medicine bubigaragaza, akayunguruzo k’amazi gakoreshwa mu bucuruzi gashobora kuba karagize uruhare mu kwandura kw’abarwayi bane babazwe umutima mu bitaro bya Brigham n’abagore, batatu muri bo bakaba barapfuye.
Icyorezo cya M. abscessus giterwa n’ubuvuzi, cyavuzwe ko ari "indwara idakunze kugaragara ariko ivugwa neza mu miyoboro y'amazi", cyahoze cyitwa "uburyo bw'amazi yanduye" nk'imashini z'urubura n'amazi, imashini zifasha mu guhumeka, imiyoboro y'amazi mu bitaro, ku barwayi babagwa byihuse, ibikoresho bishyushya no gukonjesha, imiti n'imiti yica udukoko.
Muri Kamena 2018, ishami rishinzwe kurwanya indwara zandura mu bitaro bya Brigham n'abagore ryatangaje ko Mycobacterium abscessus subsp.abscessus yanduye mu barwayi benshi bari kubagwa umutima. Indwara zandurira mu maraso, zishobora gutera indwara z'amaraso, ibihaha, uruhu, n'ingingo zoroshye, cyane cyane ku bantu bafite ubudahangarwa bw'umubiri budakomeye.
Abashakashatsi bakoze ubushakashatsi burambuye kugira ngo basobanukirwe neza amatsinda y’abanduye. Bashatse ibihuriweho hagati y’abarwayi, nk’ibikoresho bishyushya no gukonjesha bikoreshwa, cyangwa ibyumba byo kubaga, hasi mu bitaro no mu byumba, ndetse no kubona ibikoresho bimwe na bimwe. Abashakashatsi banafashe ingero z’amazi muri buri cyumba abarwayi babagamo, ndetse no mu masoko abiri yo kunywa n’ibikoresho byo gukora urubura ku gice cyo kubaga umutima.
Klompas na bagenzi be banditse ko abarwayi bose uko ari bane “bavuwe cyane hakoreshejwe imiti myinshi igabanya ubukana bw’udukoko,” ariko batatu muri bo bapfuye.
Abashakashatsi basanze abarwayi bose bari ku rwego rumwe rw’ibitaro ariko nta bindi bintu bihuriweho bari bafite. Ubwo basuzumaga ibikoresho bikora urubura n’ibikoresho bitanga amazi, babonye ukwiyongera gukomeye kwa bagiteri za mycobacteria ku duce tw’amatsinda, ariko si ahandi hantu.
Hanyuma, bakoresheje uburyo bwose bwo gusuzuma genome, basanze ibintu bisa mu ngirabuzimafatizo mu masoko yo kunywa no mu mashini z'urubura hasi mu bitaro aho abarwayi banduye bari. Amazi agana mu modoka anyura mu cyuma gisukura amazi cya karubone gihura n'urumuri rwa ultraviolet, ibyo abashakashatsi basanze bigabanya urugero rwa chlorine mu mazi, bishobora gutuma bagiteri za mycobacteria ziyongera mu modoka.
Nyuma y'uko abarwayi bari mu kaga gakomeye bahindukiriye amazi yanduye, bongera uburyo bwo kuyacunga, bagafunga uburyo bwo kuyasukura, nta yandi barwayi basigaye.
Abashakashatsi banditse bati: “Gushyiramo ibikoresho by’amazi yo mu bucuruzi kugira ngo binoze uburyohe no kugabanya impumuro mbi y’amazi yo kunywa y’abarwayi bishobora kugira ingaruka zitari ziteganijwe zo gutuma mikorobe ziyongera no kororoka.” Amazi (urugero: kongera amazi yo kongera gukoresha kugira ngo agabanye ubushyuhe) bishobora kongera ibyago byo kwandura umurwayi mu buryo butamenyekanye binyuze mu kugabanya chlorine no gutera inkunga mikorobe.”
Klompas na bagenzi be basoje bavuga ko ubushakashatsi bwabo “bugaragaza ibyago byo kugira ingaruka zitari ziteganijwe zijyanye na sisitemu zigamije kunoza ikoreshwa ry’amazi mu bitaro, ubushake bwo kwanduza mikorobe mu rubura n’amasoko yo kunywa, ndetse n’ingaruka ibi bitera ku barwayi.” inkunga ya gahunda zo gucunga amazi kugira ngo zikurikirane kandi zikumire ubwandu bwa mycobacterial yo mu gace ka nosocomial.
Banditse bati: “Muri rusange, ubunararibonye bwacu bwemeza ingaruka zishobora guterwa no gukoresha amazi yo mu robine n’urubura mu kwita ku barwayi batishoboye, ndetse n’akamaro gashoboka k’ingamba nshya zo kugabanya ibyago byo kwandura amazi yo mu robine n’urubura mu gihe cy’ubuvuzi busanzwe.”
