Fuluwenza A Virus Nucleic Acid

Kachilombo ka fuluwenza ndi mtundu woyimira wa Orthomyxoviridae. Ndi tizilombo toyambitsa matenda tomwe timawopseza kwambiri thanzi la anthu. Tikhoza kufalikira kwambiri kwa munthu amene ali ndi kachilomboka. Mliriwu umakhudza anthu pafupifupi 600 miliyoni padziko lonse lapansi ndipo umapha anthu 250,000 mpaka 500,000, ndipo kachilombo ka fuluwenza A ndiye kamayambitsa matenda ndi imfa. Kachilombo ka fuluwenza A (kachilombo ka fuluwenza A) ndi RNA yokhala ndi chingwe chimodzi. Malinga ndi hemagglutinin yake pamwamba (HA) ndi neuraminidase (NA), HA ikhoza kugawidwa m'magulu 16, NA Yogawidwa m'magulu 9. Pakati pa mavairasi a fuluwenza A, magulu a mavairasi a fuluwenza omwe amatha kufalikira mwachindunji kwa anthu ndi awa: A H1N1, H3N2, H5N1, H7N1, H7N2, H7N3, H7N7, H7N9, H9N2 ndi H10N8. Pakati pawo, mitundu ya H1, H3, H5, ndi H7 ndi yoopsa kwambiri, ndipo mitundu ya H1N1, H3N2, H5N7, ndi H7N9 ndi yofunika kwambiri kuiganizira. Kuchuluka kwa kachilombo ka fuluwenza A kumatha kusintha, ndipo n'kosavuta kupanga mitundu yatsopano, zomwe zimayambitsa mliri wapadziko lonse lapansi. Kuyambira mu Marichi 2009, Mexico, United States ndi mayiko ena ayambitsa miliri yatsopano ya fuluwenza ya mtundu A H1N1, ndipo yafalikira mofulumira padziko lonse lapansi. Kachilombo ka fuluwenza A kangathe kufalikira kudzera m'njira zosiyanasiyana monga njira yogayira chakudya, njira yopumira, kuwonongeka kwa khungu, ndi maso ndi conjunctiva. Zizindikiro pambuyo pa matendawa makamaka ndi malungo akulu, chifuwa, mphuno yotuluka madzi, myalgia, ndi zina zotero, zomwe zambiri zimayenderana ndi chibayo chachikulu. Mtima, impso ndi ziwalo zina za anthu omwe ali ndi kachilomboka kwambiri zimayambitsa imfa, ndipo chiwerengero cha imfa n'chokwera. Chifukwa chake, njira yosavuta, yolondola komanso yachangu yodziwira kachilombo ka fuluwenza A ikufunika mwachangu kuchipatala kuti ipereke chitsogozo cha mankhwala azachipatala komanso kuzindikira matenda.
