Aside ya Nucleic ya Human Cytomegalovirus (HCMV)

Virusi ya cytomegalovirusi y’umuntu (HCMV) ni imwe mu ngirabuzimafatizo nini cyane mu muryango wa virusi ya herpes kandi ishobora gushyiramo poroteyine zirenga 200. HCMV ifite agace gato k’umubiri wayo ku bantu, kandi nta n’inyamaswa isanzwe igaragara ko yanduye. HCMV ifite uruziga rwo kwisubiramo buhoro buhoro kugira ngo ikore umubiri urimo ingirabuzimafatizo, kandi igatera gukorwa kw’imibiri ihuriweho na perinuclear na cytoplasmic hamwe no kubyimba kw’uturemangingo (uturemangingo tunini), ari na yo mpamvu yitwa. Dukurikije ubwinshi bw’uturemangingo twayo na phenotype, HCMV ishobora kugabanywamo ubwoko butandukanye bw’imibiri, muri bwo hakaba harimo ubwoko bumwe na bumwe bw’imibiri irwanya indwara, ariko ntacyo buvuze ku buvuzi.

Ubwandu bwa HCMV ni ubwandu buterwa n’umubiri wose, bufata ingingo nyinshi mu buryo bw’ubuvuzi, bufite ibimenyetso bigoye kandi bitandukanye, akenshi ntibugaragara, kandi bushobora gutuma abarwayi bake bagira ibisebe mu ngingo zitandukanye harimo retinitis, hepatite, pneumonia, encephalitis, colitis, monocytosis, na thrombocytopenic purpura. Ubwandu bwa HCMV bukunze kugaragara cyane kandi busa n’aho bukwirakwira ku isi yose. Bukunze kugaragara cyane mu baturage, aho umubare w’abandura uri hagati ya 45-50% na 90% mu bihugu byateye imbere n’ibiri mu nzira y’amajyambere, uko bikurikirana. HCMV ishobora kumara igihe kirekire idakora. Iyo ubudahangarwa bw’umubiri bugabanutse, virusi itangira gukora kugira ngo itere indwara, cyane cyane indwara zisubira ku barwayi ba kanseri y’amaraso n’abarwayi batewe, kandi ishobora gutera necrosis y’ingingo zatewe kandi ikashyira mu kaga ubuzima bw’abarwayi mu bihe bikomeye. Uretse kubyara umwana wapfuye, gukuramo inda no kubyara igihe kitageze binyuze mu kwandura kw’inda, virusi ya cytomegalovirus ishobora no gutera ubumuga bwo kuvukana, bityo ubwandu bwa HCMV bushobora kugira ingaruka ku buvuzi bw’ababyeyi mbere yo kubyara no nyuma yo kubyara ndetse n’ubwiza bw’abaturage.
