A theihhuai Nattun natna (Influenza, Flu, Tot-kuae) ~ Dr. Thangboi
Swine flu leh Bird flu te ei aa ding in a lauhuai takpi mah hiam? – A beisa kum 2003 pan 2008 sung leitung mun tuamtuam (a tamzaw Asia sunga gam tuam tuam) ah Bird flu/ak nat-tun natna hangin mi 300 kim bangin sihlawh in, ak tampi leh sum leh pai tampi kisuplawh hi. A beisa ni 3 khawnga hong kipan khia Swine flu/Vok nat-tun natna hangin Mexico gamah tu ni (April 28, 2009) ciang, a si mi 149 hong pha ta hi. Tua bektham lo in USA, Canada, UK, Spain, New Zealand cih bang gam tuamtuam te ah zong tua Vok flu/nattun natna nei mi (mild cases) te mukhia ta uh hi.
Flu koi pan hong piang?
Mihing leh ganhing nam tuamtuam (tui vasa tuamtuam, ak, va tawt, vok, zawhngeu, ui, sahang, etc.) te tungah flu (ei pau in “Nat-tun”, kawl pau in “Tot-kuae”) ih cih pen virus nam khat a hi “Influenza virus Type A” hangin a kingah natna a hihi.
Hih lungno (virus) pen a diakin Vasa namte neih tawntung virus nam khat hi in, vatawt leh tuivasa pawl khat te bangin amau pumpi sungah virus a neih uh hang bangmah natna thuak lo in, a mau lengleng/ paipai na lam dungdung ah virus ki zelsak mang uh hi.
Flu virus pen a mau sunga om Haemagglutinin (HA) leh Neuraminidase (NA) kici RNA segment nam nih tungtawn in a tuam (sub-species) in kikhento lai hi. Tu ciangciang HA nam 16 leh NA nam 9 kimu khia khin ta a, tua HA leh NA tegel a ut bangun kithuah in virus nam tuam tuam hong piang thei hi (Gtn: H1N1, H2N2, H3N2, H5N1, …., H16N1, H14N9, etc.). Vasa nam sungah hih HA leh NA tuamtuam a nei virus te mukhia khin ta uh hi.
Flu han a sihna te
A masa pen flu natna pen 1878 kum in Italy gam pan Edoardo Perroncito a kici pa in hong pholak khia hi. Tuni ciang flu natna leitungbup nasia takin kizel in sihna leh natna a piansak (pandemic) 3 vei phakhin ta hi.
1. Spanish flu (1918) – H1N1 virus hang hi in, mi million 50 val bang si ding in ki-ummawh hi. World War I sangin mi tam sisak zaw hi. (tuni dong hih H1N1 virus mihing e lakah kizel lai hi).
2. Asian flu (1957) – H2N2 virus hang hi in, mi million 2 bang si ding in kiummawh hi. Hih H2N2 virus pen kum 11 sung mihing te tungah natna a piansak khit cingin, hong mangthang hi.
3. Hong Kong flu (1968) – H3N2 virus hangin, mi million 1 bangin sihlawh dingin kiummawh hi. Tuni dong hih H3N2 pen mihingte sungah omthei lai hi.
Bang hangin Flu lau huai?
Ei mihingte sungah kumsim in ih tuah den flu pen H1N1 leh H3H2 te hang hi pi pen hi. Hih virus nam 2 te pen mihing te sungah a kizelh zawh sawtta ahih manin, ih pumpi in tua natna dona (immunity) ih neikhin tek hi.
Virus thak atam zawte in ak leh vasa tuamtuam aading khauh mahmah in, mihing ta dingin natna piangsak zo lo hi. Tu laitak in mipilte patauh mahmah na a hangin, ei mihing te sungah ih tuahkhak ngei nai loh, a khauh mahmah leh mihing leh mihing a kilawhbaih mahmah virus namthak (highly pathogenic) khat hong piankhiat khakding cih thu ahi hi.
Hih bangin kilawh baih mahmah (rapid human to human transmission) leh a gu khauh mahmah virus thak khat hong piang zenzen leh kuamahn natna donatha (immunity) neinai lo ahih manin a thuakkha mi a tamzaw in sihlawh dingin kium hi. Virus natna ahih manin, natna dona zatui (vaccine/ Kar- kuae-say) bawl zawh nang a tawmpen kha 6 bang sawt ding ci uh hi. A poina khatah Virus thak hong pian mateng in Vaccine ki bawlkhol thei lo se hi.
Tua ahih manin, Virus thak hong pian leh vaccine kibawl zawh ma sungteng pen mihingte ading bang mah zatui nek ding omlo ding hi. Virus a that zatui (anti viral) a om hangin mikim ading kingah zolo ding hi. A diakin gam khangto nailo a om, gam mi ta dingin lametna tawm diak cih ding ahihi.
A masa pen flu pandemic hong pian lai (1918) in gam khatleh gamkhat kikawm nangin Tembaw (Ship) kizang lai hi. Tua hun lai nangawn in, hih flu natna leitungbup kha 2 sungin kizel zo ci uh hi. Leilu leh leitaw nikhat thu in kikawm theihna tuhun in, virus thak hong piang leh kilawh na’ng hong manlang mah mah lai ding hi.
Gamlian tampi te in tuahun hongtun khakleh kigin kholh na’ng ci in “Emergency preparedness plan” neikim uh in, a gammi khempeuh a dingin zatui (anti viral) a kicing in a neih banuh ah, vaccine a manlang penin bawlzawhnang zong kigingsa in om uhhi. Tua virus thakin hongdo sungteng a, a site kaihkhop dingdan, a nungtalai tading bangcih panpih ding cihbang ciangdong in kikup kholhsa in neikhin phitphet uh hi.
Bangciang Flu Virus thak hong piangding?
Tuni dong kuamah in ahunding genkhol theilo uhhi. A hihhang tunai ahong piangthak Bird flu leh Swine flu te I et ciang a lauhuai virus thak hongpian na’ng hongnai semsem cihpen kimu theihi.
Mihing leh mihing kilawh thei flu virus hong koici piang?
Mihing ta dingin a lauhuai lo Bird flu pan, mihing khat leh khat a kilawh thei a lauhuai mahmah flu virus thak nam 2 in hong piang thei hi.
1. Flu Pandemic masa pen (1918) Bird flu virus pan in damdam in hong kikhel in (progressive adaptation, mutation), a tawpna ciang mihing leh mihing kilawh thei , a gu khauh mahmah flu virus hong suak hi ci in um uh hi.
2. A beisa pandemic 2 na leh 3 na (1957 & 1968) te pen mihing te tung hong tun theih na’ng bird/ak sunga om flu virus in Vokpi pumpi sungah hong kipuahpha in (reassortment) in, tua hong piangthak virus in mihing leh mihing a kilawh baih thei virus thak hong suaksak hi ci in kium hi.
A lau huai pandemic flu virus hong pian na’ng bang teng kisam?
Mihing ta ding a lauhuai flu virus hong suah theih nang thu 3 kisam hi.
1. Flu virus in a gu khuah mahmah ding kisam (highly pathogenic)
2. Tua flu virus pen kilawh baih mahmah ding (ability to transmit rapidly)
3. Mihing leh mihing kilawh zo ding (ability to transmit human to human)
Tu laitak a hong lang flu virus te in number 1 leh 2 te cinzo ta hi. A thumna in hong cin ding bekin a kisam lai suak hi. Zom lai zel ni. Dr. Thangboi
