Inkcazo eneenkcukacha
Epidemic encephalitis b(encephalitis b): Lusulelo olubukhali olubangelwa yi-encephalitis b virus kwaye lusasazwa ziingcongconi.Izinga eliphezulu lokufa kunye nokukhubazeka kwe-encephalitis b sesinye sezifo ezithathelwanayo ezisongela impilo yabantu, ngakumbi abantwana.Ukuwa ixesha peak, isifo ubhubhane usasazo imimandla inxulumene ngokusondeleyo nokusasazwa ingcongconi, encephalitis b yindawo ephezulu endemic e-China, ngo-1960 kwaye ekuqaleni 70 bhubhane kazwelonke yaqhambuka emva 70 s njengoluhlu olubanzi encephalitis b ugonyo, je izehlo ziyancipha ngokuphawulekayo, kwiminyaka yakutshanje ukugcina kwinqanaba eliphantsi.Kwaye ngoku, inani leemeko ezixeliweyo ze-encephalitis b e-China phakathi kwe-5,000 kunye ne-10,000 ngonyaka, kodwa kukho ukuqhambuka okanye ubhubhane kwezinye iindawo.Ekubeni iingcongconi ziyakwazi ukuthwala intsholongwane ebusika kwaye zinokugqithiswa ukusuka kwiqanda ukuya kwiqanda, azikho nje ii-vectors zokudluliselwa, kodwa kunye nemikhosi yokugcina ixesha elide.Emva kokuba ingcongconi eyosulelwe yi-je ilume umzimba womntu, intsholongwane iqala ukwanda kwiiseli zethishu zendawo kunye ne-lymph nodes, kunye neeseli ze-vascular endothelial, ezihlasela umsinga wegazi kwaye zenze i-viremia.Esi sifo sixhomekeke kwinani leentsholongwane, i-virulence kunye nokusebenza komzimba womzimba.Uninzi lwabantu abosulelekileyo aluguli kwaye banosulelo olufihlakeleyo.Xa isixa sentsholongwane esihlaselayo sikhulu, i-virulence inamandla, kwaye umsebenzi wokuzivikela womzimba awunelanga, ngoko ke intsholongwane iyaqhubeka iphindaphinda kwaye isasazeka kuwo wonke umzimba ngegazi.Ngenxa yokuba intsholongwane ine-neurophilic nature, inokugqobhoza umqobo wegazi-ingqondo kwaye ingene kwinkqubo yemithambo-luvo.Kwiklinikhi, isetyenziselwa uxilongo oluncedisayo lwezigulane ezinosulelo lwentsholongwane ye-encephalitis b.
