Muchiri kuyeuka here kutya kwedenda reCOVID pakutanga kwegore ra2020? Apo nzvimbo dzekugezesa maoko nemidziyo yekuchenesa maoko zvaive kwese kwese, uye vanhu vaitya kubata magonhi? Tese taifunga kuti chirwere ichi chaigona kuparadzirwa chete nemunhu ari kukosora, kuhotsira, kana kubata pamusoro pechinhu chine hutachiona. Asi, chiitiko chidiki chakachinja zvese zvataitenda pakutanga. Ndizvo zvatiri kutaura nezvazvo nhasi.
Chiitiko chakachinja zvese
Izvi zvakaitika munaKurume 2020, muWashington, USA. Nhengo makumi matanhatu neimwe dzekwaya yainzi 'Skagit Valley Chorale' dzakabatana pakudzidzira kwemaawa maviri nehafu. Vakatevedzera nhungamiro dzese dzehutano panguva iyoyo. Hapana akabata mumwe munhu, vakagara chinhambwe chemamita maviri, uye vakashandisa sanitizer yemaoko zvakakwana.
Asi zvinoshamisa kuti, mukati memavhiki mashoma, vanhu 52 pavanhu ava 61 vakanga vabatwa neCOVID-19! Vamwe vavo vakatofanira kuendeswa kuchipatara, uye zvinosuwisa kuti vaviri vakafa.
Masayendisiti akashamisika pakutanga. Munhu wese akashamisika, "Izvi zvakaitika sei?" Vakanga vari kure, havana kubata mumwe nemumwe, saka vanhu vakawanda kudaro vakarwara sei panguva imwe chete?
Ndipo pakataura musayendisiti achiti, "Paiva nechinhu chimwe chete chaigovana munhu wese mukamuri iroro. Ndiyo mhepo ," uye "Hapana mubvunzo kuti chirwere chakapararira nemhepo iyoyo."
Chiitiko ichi chaive chiitiko chakakosha chakachinja zvinhu zvakawanda zvataifunga nezvedenda reCovid.
Saka, tanga tichifunga zvisizvo kwenguva yakareba here? Maonero ekare ekuti 'donhwe'
Kutaura zvazviri, kwemakore zana apfuura kana kupfuura, nyanzvi dzezvehutano dzave dzichitenda kuti zvirwere zvekufema zvakaita sedzihwa nefuruwenza zvinopararira zvikuru kuburikidza nemadonhwe makuru, anorema. Zvichitaurwa zviri nyore, madonhwe emate anobuda kana munhu achikosora kana kuhotsira.
Zvichienderana nepfungwa iyi, chirwere chinokura kana:
- Unofanira kugara pedyo zvakanyanya kana munhu anorwara achikosora kana kuhotsira.
- Kana kuti, unogona kurwara kana ukabata pamusoro (setafura kana chibato chemusuwo) une madonhwe makuru wobva wabata mhino yako, muromo, kana maziso neruoko irworwo.
Pfungwa iyi yekare (Droplet Dogma) ndiyo yakakonzera kuti tinzwe tichida kugara kure nemamita matanhatu uye kupukuta zvese nemushonga wekuuraya utachiona mumazuva ekutanga kweCovid.
Asi nezvakaitika kuboka iroro, masayendisiti akaona kuti pane chikanganiso chikuru munyaya iyi pane imwe nzvimbo. Panofanira kunge paine nzira iri nyore yekupararira kwechirwere ichi.
'Droplet' uye 'aerosol' - musiyano uripi?
Apa ndipo patinosangana neshoko idzva - 'aerosol'. Izvi zvakakosha kunzwisisa. Funga nezvebhodhoro rekupfapfaidza. Paunopfapfaidza, madonhwe makuru emvura anowira pasi, uye kunewo zvidimbu zvidiki zvemvura zvisingaonekwe zvinoyangarara mumhepo, semhute, handiti? Ndizvo zvazviri.
'Madonhwe' akafanana nemadonhwe makuru iwayo. 'Maaerosols' akafanana netunhu tudiki twuri kuyerera mumhepo.
Ngatitarisei musiyano uripo pakati pezviviri izvi nenzira iyi.
| Hunhu | Madonhwe makuru (Madonhwe) | Zvidimbu zvidiki kwazvo (Aerosols) |
|---|---|---|
| Saizi | Yakakura zvishoma (kunyange isingaonekwe neziso) | Diki zvikuru (senge utsi) |
| Mhedzisiro pagiravhiti | Inodonha pasi nekukurumidza (mumasekonzi/maminitsi mashoma) nekuda kwehuremu hwayo. | Nekuti yakareruka, inogona kubhururuka mumhepo kwemaminitsi, pamwe maawa. |
| Nhanho yekufamba | Nhanho pfupi (inenge mamita 1-2). | Inogona kutopararira mukamuri rese. |
| Kupararira kwazvinoita | Nekupinda mumuviri zvakananga kana mumwe munhu achikosora kana kuhotsira ari pedyo. | Kana munhu ane hutachiona akafema, achitaura, kana kuimba, hunopinda mumhepo uye hunofemedzwa. |
Nhengo dzekwaya iyoyo padzakaimba, zvidimbu zvidiki izvi (maaerosols) zvakaburitswa mumhepo yadzo.Imba yese inofanira kunge yakanga yakazara nemhepo. Kunyangwe vaive kure nekure, vese vaifema mweya mumwe chete, saka vanhu vakawanda vairwara. Izvi zvinonzi airborne transmission .
Ruzivo rutsva rwakachinja sei hupenyu hwedu
Nekuwana uku, nzira dzatakashandisa kudzora denda dzakachinja zvachose.
Kubva pakuchenesa nzvimbo kusvika pakufunga nezvemhepo
Pakutanga, taifunga kuti kupukuta pasi, matafura, uye magonhi ndicho chinhu chakakosha. Asi mushure mekuona kuti zviri mumhepo, takadzidza kuti pane chimwe chinhu chakakosha kupfuura izvi. Uye ndiko kufefetera kwakanaka.
Zvichitaurwa zviri nyore, kuchengetedza magonhi nemahwindo akavhurika uye kushandisa feni kutenderedza mhepo kunoderedza kuwanda kwetupukanana twemavhairasi panzvimbo imwe chete.
Kukosha kwechokwadi kwemasiki
Pakutanga, mamasiki aipfekwa kudzivirira madonhwe makuru ataikosora. Asi gare gare zvakazoonekwa kuti mask yakanaka yakaita seN95 inogona kusvina kunyangwe tupukanana tudiki twemavhairasi (maaerosols) twaifamba mumhepo. Nokudaro, kukosha kwemasiki kwakawedzera zvakanyanya.
Ruzivo urwu ruchatibatsira zvikuru kuzvidzivirira kwete kubva kuCovid chete, asiwo kubva kune chero denda rezvirwere zvekufema remangwana.
Mharidzo Yekuenda Nayo Kumba
- Zvirwere zvekufema zvakaita seCOVID-19 zvinogona kupararira kuburikidza nemadonhwe makuru anoburitswa kana munhu akosora, pamwe chete netunhu tudiki (maaerosols) tunoyangarara mumhepo paanotaura kana kufema.
- Njodzi yekupararira kwehutachiona yakanyanya munzvimbo dzakavharwa (makamuri, mabhazi). Saka, zvakakosha kuchengetedza mhepo yakanaka , zvinoreva kuchengetedza mahwindo akavhurika.
- Kupfeka mamasiki kunobatsira kudzivirira madonhwe makuru uye zvidimbu zvidiki zvinoyangarara mumhepo.
- Sainzi haisi yekuchinja-chinja. Ruzivo rwedu nekunzwisisa kwedu zvinochinja sezvo humbowo hutsva huchiwanikwa. Madenda ndiwo muenzaniso mukuru weizvozvo.
