Eksperdid arutlevad, kas koroonaviirus levib selle kahjuliku harjumusega

Teadlased arvavad praeguste andmete põhjal, et koroonaviirus levib suu- ja ninaeritistega, kui ollakse lähikontaktis nakatunuga. Nendeks eritisteks on sülg ja köhides, aevastades, rääkides või lauldes suust erituvad tilgakesed. Kuid kas passiivse suitsetamisega võib saada koroonaviiruse?

Lühike vastus on: see on võimalik. Kuigi passiivse suitsetamisega koroonaviiruse levikut pole veel uuritud, siis samasugused eelmainitud tilgakesed levivad ka suitsetamise ja veipimisega. Lisaks, on võimalik et väiksemad tilgakesed püsivad õhus aerosoolina, rääkis California St. Jude meditsiinikeskuse kopsuarst Julie Lyou veebiväljaandele Health.

See tähendab, et passiivse suitsetamisega koroonaviirusesse nakatumine on võimalik. «Usutavasti võib eeldada, et hingamisteede tilkadest koosnev suitsupilv võib põhjustada Covid-19 ülekandumist,» ütles rindkere kirurg Osita Onugha. Väljahingamise ja suitsu väljahingamise vahe on ka see, et ühte saab läbi maski teha, teist mitte.

«Kuna uudne koroonaviirus levib inimeselt inimesele kontaktiga, siis lähedast kontakti (vähem kui kaks meetrit) hõlmavaid maskita tegevusi tuleks vältida,» ütles doktor Lyou, «Suitsetamiseks peab inimene maski maha võtma, mistõttu on see kõrge riskiga keskkond kõigile lähedal viibivatele inimestele.»

Kuigi pole tõendeid, et suits levitab viirust kaugemale, pole doktor Onugha sõnul turvalist distantsi, mida soovitada suitsetajate lähedal seisvatele inimestele. Ta soovitab viiruse edasikandumise riski vähendamiseks näomaski kanda.

Suitsetajatel endil on suurem koroonaviirusesse nakatumise risk. Tubakakontrolli uuringute ja hariduse keskus California ülikoolis San Franciscos tegi 19 suitsetamise ja koroonaviiruse kulgemise teadusartikli põhjal ülevaateuuringu. 17 uuringut olid Hiinast, üks Koreast ja üks Ameerika Ühendriikidest. Leiti, et suitsetamine kahekordistas koroonaviiruse progresseerumise tõenäosust.

Mais teatas Maailma Terviseorganisatsioon, et «suitsetajatel kulgeb võrreldes mittesuitsetajatega tõenäolisemalt koroonaviirus raskemalt». Hoolimata koroonaviirusest, peaksid mittesuitsetajad passiivset suitsetamist vältima. «Uuringud on näidanud, et passiivne suitsetamine on seotud suurema kopsuvähi ja südame-veresoonkonnahaiguste (südameatakk ja insult) riskiga,» selgitas doktor Lyou. «Isegi lühiajaline kokkupuude sigaretisuitsuga võib halvendada eelnevaid kopsuhaigusi, nagu astma ja krooniline obstruktiivne kopsuhaigus.»

My name is Carol Ronald from USA, I recently saw a testimony by “Alice Alfie from London” about a spell caster DR.Iwisa in a blog I visit for relationship and dating problems because I had been having serious issues with my boyfriend and we had been dating for 3 year, He just suddenly changed and started cheating on me on several occasion, He was hurting me in so many ways I never thought possible and I just thought I should try this spell caster called DR.Iwisa because there are so many good testimonies about him on the website, I was scared a little because I had read and heard lots of stories of fake spell casters scam and I never really believed in magic. I played along with a little hope and faith and everything went to a whole new direction after he finished the love spell. I guess it was all good faith that made me read that particular testimony that faithful day.I hope they could help other people too like they did to me. I did a little and I got everything I wanted and wished for, my boyfriend and my life is back. You can contact DR.Iwisa because he changed my life
