Den senaste tidens intresse f\u00f6r coronavirussmitta p\u00e5 grund av covid-19-pandemin motiverade flera specifika forskare med relevant \u00f6vers\u00e4ttning till v\u00e5rt dagliga liv. Artikeln med titeln Aerosol and Surface Stability of SARS-Cov2, nyligen publicerad i New England Journal of Medicine <\/a> l\u00e4r oss n\u00e5got mycket relevant: hur l\u00e4nge h\u00e5ller sig coronaviruset Covid-19 \"vid liv\" efter att ha l\u00e4mnat kroppen p\u00e5 en infekterad patient?<\/p>\n

Svaret beror p\u00e5 vilken typ av material det r\u00f6r sig om. Diagrammen nedan visar hur mycket virus som finns i ytorna \u00f6ver tiden. Detta kallas virusets \"titel\" och anv\u00e4nds f\u00f6r att ber\u00e4kna halveringstiden, dvs. hur l\u00e5ng tid det tar f\u00f6r virusets titel att sjunka till h\u00e4lften. Avklingningshastigheten ger oss en uppfattning om hur \"livskraftigt\" coronaviruset Covid-19 \u00e4r p\u00e5 varje yta. Ju mindre livskraftigt, desto b\u00e4ttre .... f\u00f6r oss, inte f\u00f6r dem.<\/p>\n

F\u00f6rfattarna rapporterar tester av virusets livskraftiga halveringstid i aerosol (efterliknar det stavade sekretet under en nysning), i koppar, kartong, rostfritt st\u00e5l och plast.<\/p>\n\n\n\n

\"Livsl\u00e4ngd
Ytlivsl\u00e4ngd f\u00f6r coronaviruset Covid-19 i aerosol, koppar, kartong, rostfritt st\u00e5l och plast.<\/figcaption><\/figure>\n\n\n\n

Enligt de rapporterade uppgifterna var coronaviruset Covid-19 mer stabilt p\u00e5 plast och rostfritt st\u00e5l \u00e4n p\u00e5 koppar och kartong, och livskraftigt virus kunde p\u00e5visas upp till 72 timmar efter applicering p\u00e5 dessa ytor.<\/p>\n

Halveringstiden f\u00f6r det viabla viruset \u00e4r ca 1 timme i aerosol eller koppar, 3 timmar i kartong och \u00f6ver 5 timmar i rostfritt st\u00e5l och plastytor.<\/p>\n

Slutsatsen \u00e4r att plastflaskorna i kylsk\u00e5pet eller besticken kan vara det b\u00e4sta st\u00e4llet f\u00f6r viruset att fastna, om n\u00e5gon i din familj \u00e4r assymptomatiskt smittad och smittar de andra utan att veta om det. Det b\u00e4sta r\u00e5det \u00e4r att sluta dela dessa f\u00f6rem\u00e5l med de andra, bara f\u00f6r att vara p\u00e5 den s\u00e4kra sidan.<\/p>\n

En annan inte helt sj\u00e4lvklar slutsats \u00e4r att plastp\u00e5sen i snabbk\u00f6pet f\u00f6rmodligen \u00e4r farligare \u00e4n pizzakartongen fr\u00e5n budet... bara en gissning, men jag tycker att det l\u00e5ter vettigt.<\/p>\n\n\n\n

\"\"<\/p>\n

I de vanliga ytor som anv\u00e4nds f\u00f6r att b\u00e4ra varor f\u00f6rblir coronaviruset Covid-19 inte livskraftigt efter 24 timmar. S\u00e5 n\u00e4r du kommer tillbaka fr\u00e5n mataff\u00e4ren, stormarknaden eller apoteket kan det vara bra att l\u00e4mna p\u00e5sarna (eller \u00e4nnu b\u00e4ttre, l\u00e5dorna) obevakade under en dag och komma tillbaka senare. Det \u00e4r f\u00f6rmodligen mycket s\u00e4krare, och s\u00e4rskilt anv\u00e4ndbart, om du inte vill b\u00e4ra handskar och reng\u00f6ra varje f\u00f6rem\u00e5l du tog med hem.<\/p>\n

En annan viktig slutsats \u00e4r att coronaviruset covid-19 f\u00f6rmodligen sprids mer \u00e4n tidigare virus fr\u00e5n samma klass p\u00e5 grund av inneboende faktorer i dess natur, inklusive h\u00f6g virusbelastning i de \u00f6vre luftv\u00e4garna och m\u00f6jligheten f\u00f6r personer infekterade med SARS-CoV-2 att uts\u00f6ndra och \u00f6verf\u00f6ra viruset medan de \u00e4r symptomfria.  <\/p>\n

S\u00e5 \u00e4ven om coronaviruset Covid-19 fastnar p\u00e5 vissa ytor \u00e4r den st\u00f6rsta faran helt klart direktkontakt med smittade m\u00e4nniskor. Coronaviruset f\u00f6rblir inte livskraftigt l\u00e4nge i aerosolen, men ibland r\u00e4cker det med att vara n\u00e4ra n\u00e5gon. Var uppm\u00e4rksam p\u00e5 personen som hostar utan mask och kom inte n\u00e4rmare f\u00f6r att fr\u00e5ga om han\/hon testat positivt. Det spelar ingen roll, b\u00e4ttre att vara s\u00e4ker och till\u00e4mpa social isolering f\u00f6r att f\u00f6rhindra \u00f6verf\u00f6ring av coronaviruset<\/a>. Okej?<\/p>\n
