Viimeaikainen kiinnostus Covid-19-pandemian aiheuttamaa koronaviruksen levi\u00e4mist\u00e4 kohtaan on motivoinut useita erityisi\u00e4 tutkijoita, joilla on merkityst\u00e4 jokap\u00e4iv\u00e4isess\u00e4 el\u00e4m\u00e4ss\u00e4mme. Tutkimus, jonka otsikkona on SARS-Cov2:n aerosoli- ja pintastabiliteetti julkaistiin hiljattain New England Journal of Medicine -lehdess\u00e4. <\/a> opettaa meille jotain hyvin olennaista: kuinka kauan koronavirus Covid-19 pysyy \"elossa\" sen j\u00e4lkeen, kun se on poistunut tartunnan saaneen potilaan kehosta?<\/p>\n

Vastaus riippuu materiaalin tyypist\u00e4. Alla olevissa kaavioissa on esitetty pinnoilla havaittu viruksen m\u00e4\u00e4r\u00e4 ylit\u00f6in\u00e4. T\u00e4t\u00e4 kutsutaan viruksen \"otsikoksi\", ja sit\u00e4 k\u00e4ytet\u00e4\u00e4n puoliintumisajan laskemiseen eli siihen, kuinka kauan kest\u00e4\u00e4, ett\u00e4 viruksen otsikko laskee puoleen. Hajoamisnopeus antaa meille k\u00e4sityksen siit\u00e4, kuinka \"elinkelpoinen\" coronavirus Covid-19 on kullakin pinnalla. Mit\u00e4 v\u00e4hemm\u00e4n elinkelpoinen, sit\u00e4 parempi.... meille, ei niille.<\/p>\n

Kirjoittajat raportoivat viruksen elinkelpoisen puoliintumisajan testaamisesta aerosolissa (joka j\u00e4ljittelee aivastuksen aikana erittyv\u00e4\u00e4 eritett\u00e4), kuparissa, pahvissa, ruostumattomassa ter\u00e4ksess\u00e4 ja muovissa.<\/p>\n\n\n\n

\"Covid-19-koronaviruksen
Coronavirus Covid-19:n pintaelinaika aerosolissa, kuparissa, pahvissa, ruostumattomassa ter\u00e4ksess\u00e4 ja muovissa.<\/figcaption><\/figure>\n\n\n\n

Raportoitujen tietojen mukaan Covid-19-koronavirus oli vakaampi muovilla ja ruostumattomalla ter\u00e4ksell\u00e4 kuin kuparilla ja pahvilla, ja elinkelpoinen virus havaittiin jopa 72 tunnin kuluttua levitt\u00e4misest\u00e4 n\u00e4ille pinnoille.<\/p>\n

Elinkykyisen viruksen puoliintumisaika on noin 1 tunti aerosolissa tai kuparissa, 3 tuntia pahvissa ja yli 5 tuntia ruostumattomassa ter\u00e4ksess\u00e4 ja muovipinnoilla.<\/p>\n

Johtop\u00e4\u00e4t\u00f6s on, ett\u00e4 j\u00e4\u00e4kaapin muovipullot tai ruokailuv\u00e4lineet voivat olla paras paikka viruksen tarttumiselle, jos joku perheest\u00e4si on oireettomasti saastunut ja tartuttaa muita tiet\u00e4m\u00e4tt\u00e4\u00e4n. Paras neuvo on lopettaa n\u00e4iden esineiden jakaminen muiden kanssa varmuuden vuoksi.<\/p>\n

Toinen ei itsest\u00e4\u00e4n selv\u00e4 johtop\u00e4\u00e4t\u00f6s on se, ett\u00e4 muovipussi supermarketissa on luultavasti vaarallisempi kuin pizzalaatikko, jonka jakelukuski on tuonut... vain arvaus, mutta mielest\u00e4ni siin\u00e4 on j\u00e4rke\u00e4.<\/p>\n\n\n\n

\"\"<\/p>\n

Tavaroiden kuljettamiseen k\u00e4ytetyill\u00e4 tavanomaisilla pinnoilla Covid-19-koronavirus ei pysy elinkelpoisena 24 tunnin j\u00e4lkeen. Kun siis palaat ruokakaupasta, supermarketista tai apteekista, voi olla hy\u00f6dyllist\u00e4 j\u00e4tt\u00e4\u00e4 pussit (tai paremmin laatikot) yhden p\u00e4iv\u00e4n ajaksi ilman valvontaa ja tulla my\u00f6hemmin. Se on luultavasti paljon turvallisempaa,ja erityisen hy\u00f6dyllist\u00e4, jos et halua k\u00e4ytt\u00e4\u00e4 k\u00e4sineit\u00e4 ja puhdistaa jokaista kotiin tuomaa tuotetta.<\/p>\n

Toinen t\u00e4rke\u00e4 johtop\u00e4\u00e4t\u00f6s on, ett\u00e4 Covid-19-koronavirus levi\u00e4\u00e4 todenn\u00e4k\u00f6isesti enemm\u00e4n kuin aiemmat samaan luokkaan kuuluvat virukset, mik\u00e4 johtuu sen luonteeseen liittyvist\u00e4 tekij\u00f6ist\u00e4, kuten korkeasta viruskuormituksesta yl\u00e4hengitysteiss\u00e4 ja siit\u00e4, ett\u00e4 SARS-CoV-2:een sairastuneet henkil\u00f6t voivat eritt\u00e4\u00e4 ja levitt\u00e4\u00e4 virusta oireettomina.  <\/p>\n

Vaikka Covid-19-koronavirus tarttuu tiettyihin pintoihin, suurin vaara on selv\u00e4sti suora kosketus saastuneisiin ihmisiin. Koronavirus ei pysy elinkelpoisena aerosolissa pitk\u00e4\u00e4n, mutta joskus riitt\u00e4\u00e4, ett\u00e4 on l\u00e4hell\u00e4 jotakuta. Huomioi ilman maskia yskiv\u00e4 henkil\u00f6, \u00e4l\u00e4k\u00e4 tule l\u00e4hemm\u00e4s kysym\u00e4\u00e4n, onko h\u00e4nen testins\u00e4 positiivinen. Sill\u00e4 ei ole v\u00e4li\u00e4, on parempi olla turvassa ja harjoittaa sosiaalista erist\u00e4mist\u00e4 koronaviruksen levi\u00e4misen est\u00e4miseksi.<\/a>. Onko selv\u00e4?<\/p>\n
