Ingabe ukuhlanza izandla noma ukugeza izandla kungawubulala umkhuhlane?

Imfundo Yezempilo

Kusukela kwaqala ubhadane lwe-COVID-19, uzobona i-sanitizer yezandla cishe yonke indawo: amabhange, imigqa yokuphuma esitolo, iposi, nezindlu zangasese zomphakathi. Sitshelwe ukuthi kuyindlela yesibili engcono kakhulu yokugeza izandla uma insipho enhle ye-ol namanzi engekho. Ngabe i-sanitizer yesandla iyisitha esesabekayo segciwane lomkhuhlane? Noma ingabe insipho namanzi akudala? Yebo, ngokusho kocwaningo luka-2019, luyinkimbinkimbi.

Ingabe i-sanitizer yesandla iyalibulala igciwane lomkhuhlane?

Lapho igciwane lomkhuhlane libhajwe emafinyileni omanzi, lingahlala litheleleka kuze kube yimizuzu emine ngemuva kokuchayeka kwi-sanitizer yezandla-ngamanye amagama, isikhathi eside kakhulu kunalokho obekucabanga. Lokhu yilokho a isifundo sakamuva itholakale lapho kudonsa amathonsi emifino emanzi aqukethe i- Umkhuhlane Igciwane ezandleni zamavolontiya anesibindi.

Lapho igciwane lomkhuhlane limiswa kusixazululo sikasawoti, isibulala-magciwane salibulala leli gciwane ngemizuzwana engama-30. Lapho isetshenziswa kumagciwane omkhuhlane omisiwe, i-hand sanitizer yabulala leli gciwane ngemizuzwana eyisishiyagalombili nje.

Abaphenyi, abavela IKyoto Prefectural University of Medicine , Isizathu sokuthi amafinyila aminyene, angamaqhuqhuva enza njengesihlangu esizungeze igciwane, evimbela isikhucululi sesandla ekungeneni ngokuphelele kuso. I-Saline-hhayi i-goopy noma i-thick-ayilinganisi ikhono le-sanitizer lokungena ku-virus futhi lenze umsebenzi walo. I-Ditto yamafinyila omisiwe. Yingakho isikhathi sokuqeda leli gciwane sehluka kakhulu.

Akuwona wonke umuntu odalulwe yigciwane lomkhuhlane onokunethezeka kokukhetha indlela igciwane eligcina ngayo ezandleni zakhe — kumafinyila, usawoti, noma omisiwe. Ngakho-ke kubalulekile ukwazi ukuthi kuthatha isikhathi esingakanani ukuthi i-sanitizer yezandla isebenze kahle. Ngaphandle kwalokho, ungazibeka engozini yokutheleleka noma usabalalise leli gciwane kwabanye.

OKUhlobene : Ungawuvikela kanjani umkhuhlane

Ingabe ukugeza izandla kuyabulala umkhuhlane?

Ngokwalolu cwaningo, ukugeza izandla — ngisho ungenayo insipho ngisho nalapho amafinyila analesi sifo sekumanzi — empeleni kwakusebenza kakhulu ekususeni igciwane lomkhuhlane. Kuyisusile ngemizuzwana engama-30 kuphela. Inkinga kuphela ukuthi abantu abaningi abazigezi izandla zabo cishe isikhathi eside kangako, futhi ezimweni eziningi insipho namanzi ahambayo akutholakali nje. Kulezo zimo, ingabe i-sanitizer yesandla ayinalutho?

OKUSHIWO: Ukugeza izandla 101

Konke kumayelana nokuhlanzeka kwesandla esifanele

Akunandaba ukuthi ukhetha yiphi indlela — i-sanitizer noma insipho namanzi — okusemqoka ukuthi uhlanza kahle kangakanani nokuthi uhlala isikhathi esingakanani. Akuyena wonke umuntu ovumelana nokutholakele okusha, ikakhulukazi ngoba abacwaningi abazange bafunde ukuthi i-sanitizer yezandla isebenza kanjani lapho ihlikihlwa esikhunjeni, kuphela lapho ibhajwe eminwe.

Le mpi yayingalungile, kusho uCarl Fichtenbaum, MD, uprofesa wezokwelapha eMnyangweni Wezokwelapha Wangaphakathi, ukuhlukaniswa kwezifo ezithathelwanayo Inyuvesi yaseCincinnati College of Medicine . Izinto zokuhlanza izandla zihlala zisetshenziswa ngokunyakaza kokuhlikihla — kufanele ukugcobise ezandleni zakho ukuze zikwazi ukuhwamuka futhi zincibilike. Yilokho ukuhlolwa kwangempela okwakudinga ukwenziwa. Ukuzihlikihla ngesandla kuyingxenye ebucayi yakho konke lokhu.

Michael Chang, MD, udokotela wezifo zezingane ezithathelwanayo kanye nosizi likaprofesa wezifo zezingane e Isikole Sezokwelapha iMcGovern e-UTHealth eHouston , iyavumelana. Amathuba okuthi ungadonsela i-sanitizer yesandla esandleni sakho bese uyivumela ukuthi ihlale lapho iphansi, kusho uDkt Chang. Akekho osebenzisa i-sanitizer yesandla ngaleyo ndlela.

Bobabili uDkt. UFichtenbaum noChang baphawule ukuthi kungaphezu kwesenzo samakhemikhali se-sanitizer yesandla esenza sisebenze-futhi isenzo sokuhlikihla izandla ndawonye. Ngicabanga ukuthi ukube abacwaningi bebebheke ukuhlikihla i-sanitizer yezandla ezandleni naseminwe, kungenzeka ukuthi ibisebenza njengokugeza izandla ekubulaleni leli gciwane, kusho uDkt Fichtenbaum.

Abaphenyi bakuvumile ukulinganiselwa kwesifundo sabo futhi babheke ekwandiseni ucwaningo lwabo ukuze lubandakanye ukuxubha izandla.

Siqinisekisa ukubaluleka kwesayensi ngesenzo sokuzihlikihla ngesandla ukuze siphakamise uhlobo oluhle kakhulu lokuhlikihla izandla, kushoURyohei Hirose, umbhali oholayo wesifundo.Ukuzihlikihla ngesandla kulindeleke ukuthi kube nomthelela omkhulu ekwandeni kwesilinganiso sokuhlushwa kwe-ethanol kumafinyela athelelanayo ngenxa yokwanda kwe-convection.

Nini (futhi kanjani) ukusebenzisa kahle i-sanitizer yezandla

Ochwepheshe bathi ukuvikeleka okungcono kakhulu emkhuhlaneni ukushaywa umkhuhlane, bese kwenziwa inhlanzeko efanelekile yezandla. Okushoyo, qiniseka ukuthi usebenzisa isihlanzisi esisebenzayo futhi usisebenzisa ngendlela efanele.

Uma usebenzisa i-sanitizer yesandla, i- Izikhungo Zokulawulwa Nokuvikelwa Kwezifo (CDC) incoma lokhu okungafanele kwenziwe nokungafanele ukwenze.

• Ingabe sebenzisa i-sanitizer yesandla okungenani i-60% ethanol alcohol.
• Ingabe gcoba i-sanitizer entendeni yesandla sakho (funda izinkomba zomkhiqizo ngenani elifanele-imvamisa i-squirt noma amabili) bese uhlikihla kuyo yonke indawo yezandla zombili kuze kube yilapho i-sanitizer yomile (cishe amasekhondi angu-20-30).
• Ingabe gcoba i-sanitizer phakathi kwezikhala zeminwe futhi phezulu phezulu ngaphansi kwezipikili.
• Ungenzi sebenzisa i-sanitizer yesandla uma izandla zibonakala zingcolile noma zinamafutha, izinto ezimbili ezenza kube nzima ukuthi i-sanitizer ingene kumagciwane.

Uma usebenzisa insipho namanzi, i-CDC incoma lezi zinyathelo:

• Manzisa izandla zakho ngamanzi ahlanzekile ahlanzekile — kushisa noma kubanda.
• Faka insipho. Akudingeki ukuthi ibe yi-antibacterial.
• Hlikihla izintende zezandla zakho, emuva kwezandla kuze kufike ezihlakaleni, phakathi kweminwe nangaphansi kwezipikili okungenani imizuzwana engama-20. Cishe isikhathi esithathayo ukucula iculo lokuzalwa olujabulisayo kabili.
• Hlanza izandla zakho kahle.
• Yomile ngethawula elihlanzekile, noma umoya owomile.

Akunandaba ukuthi ukhetha yiphi indlela, uma ulandela lezi zinyathelo, kungenzeka ukuthi ugweme ifayela le- kubanda, umkhuhlane, noma i-COVID-19 .
