Umkhuhlane A Virus Nucleic Acid

Igciwane lomkhuhlane liwuhlobo olumele i-Orthomyxoviridae.Kuyi-pathogen esongela kakhulu impilo yomuntu.Ingathelela umsingathi kakhulu.Ubhubhane lwesizini luthinta abantu ababalelwa ezigidini ezingama-600 emhlabeni wonke futhi lubangela ukufa kwabantu abangu-250,000 ~ 500,000, okukhona igciwane lomkhuhlane A eliyimbangela enkulu yokutheleleka nokufa.Igciwane lomkhuhlane A (igciwane loMkhuhlane A) liyi-RNA enomucu owodwa onegayo.Ngokusho kwe-surface hemagglutinin (HA) kanye ne-neuraminidase (NA), i-HA ingahlukaniswa ngama-subtypes ayi-16, i-NA Ihlukaniswe yaba yi-9 subtypes.Phakathi kwamagciwane omkhuhlane A, izinhlobo ezincane zamagciwane omkhuhlane ezingathelela abantu ngokuqondile yilezi: A H1N1, H3N2, H5N1, H7N1, H7N2, H7N3, H7N7, H7N9, H9N2 kanye ne-H10N8.Phakathi kwazo, i-H1, H3, H5, ne-H7 subtypes i-pathogenic kakhulu, futhi i-H1N1, i-H3N2, i-H5N7, ne-H7N9 ifaneleka ngokukhethekile ukunakwa.I-antigenicity yegciwane lomkhuhlane A ijwayele ukushintsha, futhi kulula ukwakha izinhlobo ezincane, okubangela ubhubhane lomhlaba wonke.Kusukela ngo-March 2009, i-Mexico, i-United States kanye namanye amazwe ngokulandelana kwaqubuka uhlobo olusha lwe-H1N1 ubhubhane lomkhuhlane, futhi lusakazekele emhlabeni ngokushesha.Igciwane loMkhuhlane A lingasakazwa ngezindlela ezihlukahlukene ezifana nomgudu wokugaya ukudla, umgudu wokuphefumula, ukulimala kwesikhumba, kanye neso kanye ne-conjunctiva.Izimpawu ngemva kokutheleleka ikakhulukazi umkhuhlane ophezulu, ukukhwehlela, ikhala eligijimayo, i-myalgia, njll., iningi lazo elihambisana ne-pneumonia enzima.Inhliziyo, izinso nezinye izitho zomzimba zabantu abangenwe yilesi sifo kuholela ekufeni, kanti izinga lokufa liphezulu.Ngakho-ke, indlela elula, enembile futhi esheshayo yokuxilonga igciwane lomkhuhlane A idingeka ngokushesha emtholampilo ukuze kuhlinzekwe isiqondiso semithi yokwelapha kanye nokuxilongwa.
