Diease ya Legionnaires, yitiriwe icyorezo mu 1976 mu ikoraniro ry’Abanyamerika rya Legio ryabereye i Philadelphia, iterwa na pionumophila ya Legionella kandi irangwa n'indwara ikabije y'ubuhumekero ya febrile iterwa n'uburemere bukabije kuva indwara zoroheje kugeza umusonga wica.Indwara ibaho haba mu byorezo ndetse no mu cyorezo kandi indwara rimwe na rimwe ntizitandukana byoroshye n’izindi ndwara z’ubuhumekero n’ibimenyetso by’amavuriro.Abagera kuri 25000 kugeza 100000 banduye Legionella bandura muri Amerika buri mwaka.Umubare w'impfu zavuyemo, uri hagati ya 25% na 40%, urashobora kugabanuka mugihe iyi ndwara isuzumwe vuba kandi hakwiye kuvurwa imiti igabanya ubukana hakiri kare.Impamvu zizwi zishobora guteza indwara zirimo immunosuppression, kunywa itabi, kunywa inzoga n'indwara zifata ibihaha.Abato n'abakuru barashobora kwibasirwa cyane.Pneumophila ya Legionella ishinzwe 80% -90% by'abantu banduye banduye indwara ya Legionella hamwe na serpgroup 1 bangana na 70% bya legionellose.Uburyo bugezweho bwo kumenya laboratoire yatewe n'umusonga uterwa na Legionella pneumophila bisaba urugero rwubuhumekero (urugero: sputum yanduye, gukaraba bronchial, transtracheal aspirate, ibihaha biopsy) cyangwa sera byombi (acute na convalescent) kugirango isuzume neza.
BYIZA Legionella yemerera kwisuzumisha hakiri kare ya Legionella pneumophila serogroup 1 infevtion binyuze mugushakisha antigen yihariye iboneka muminkari yabarwayi bafite indwara ya Legionnaires.Legionella pneumophila serogroup 1 antigen yamenyekanye mu nkari hashize iminsi itatu ibimenyetso bitangiye.Ikizamini kirihuta, gitanga ibisubizo muminota 15, kandi kigakoresha urugero rwinkari zorohereza gukusanya, gutwara, no gutahura hakiri kare, kimwe na nyuma yindwara.
