HEV (Byihuta)

Hepatite E (Hepatitis E) n'indwara ikaze yandura yanduzwa n'umwanda.Kuva icyorezo cya mbere cya hepatite E kibera mu Buhinde mu 1955 kubera kwanduza amazi, cyiganje mu Buhinde, Nepal, Sudani, Kirigizisitani yo muri Leta Zunze Ubumwe z'Abasoviyeti, Ubushinwa ndetse n'ahandi mu Bushinwa.

HEV isohoka mu mwanda w'abarwayi, ikwirakwizwa binyuze mu mibereho ya buri munsi, kandi irashobora gukwirakwizwa cyangwa kwandura icyorezo cyatewe n'ibiryo byanduye n'amasoko y'amazi.Impanuka yibisanzwe mubisanzwe mugihe cyimvura cyangwa nyuma yumwuzure.Igihe cyo gukuramo ni ibyumweru 2 ~ 11, ugereranije n'ibyumweru 6.Benshi mu barwayi bo mu mavuriro ni hepatite yoroheje kandi yoroheje, akenshi irigabanya, kandi ntibakura muri HEV idakira.Yibasira cyane cyane abakiri bato, barenga 65% muribo biboneka mumyaka iri hagati yimyaka 16 na 19, kandi abana bafite indwara zanduye.

Umubare w'abahitanwa n'abantu bakuze uruta uw'umwijima wa A, cyane cyane ku bagore batwite barwaye hepatite E, kandi umubare w'abahitanwa n'ubwandu mu mezi atatu ashize batwite ni 20%.
Nyuma yo kwandura HEV, irashobora gutanga ubudahangarwa bw'umubiri kugirango irinde HEV kwanduza ubwoko bumwe cyangwa se ubwoko butandukanye.Byavuzwe ko antibody anti-HEV muri serumu y’abarwayi benshi nyuma yo gusubiza mu buzima busanzwe imara imyaka 4-14.
Kugira ngo hasuzumwe ubushakashatsi, uduce twa virusi dushobora kuboneka mu mwanda na microscope ya electron, HEV RNA mu mara ya fecal irashobora gutahurwa na RT-PCR, kandi antibodiyite anti-HEV IgM na IgG muri serumu zishobora gutahurwa na ELISA ukoresheje recombinant HEV glutathione S-transfera proteine ​​nka antigen.
Kwirinda muri rusange indwara ya hepatite E ni kimwe na hepatite B. Immunoglobuline isanzwe ntigira ingaruka zo gukingira byihutirwa.
