Interesul recent pentru transmiterea coronavirusului datorat pandemiei Covid-19 a motivat mai mul\u021bi cercet\u0103tori specifici cu o traducere relevant\u0103 pentru via\u021ba noastr\u0103 de zi cu zi. Lucrarea intitulat\u0103 Stabilitatea aerosolului \u0219i a suprafe\u021bei SARS-Cov2 publicat\u0103 recent \u00een New England Journal of Medicine <\/a> ne \u00eenva\u021b\u0103 ceva foarte relevant: c\u00e2t timp r\u0103m\u00e2ne \"viu\" coronavirusul Covid-19 dup\u0103 ce p\u0103r\u0103se\u0219te corpul unui pacient infectat?<\/p>\n

R\u0103spunsul depinde de tipul de material. Graficele de mai jos arat\u0103 cantitatea de virus g\u0103sit\u0103 pe suprafe\u021be \u00een timp. Acest lucru se nume\u0219te \"titlu\" al virusului \u0219i este utilizat pentru a calcula timpul de \u00eenjum\u0103t\u0103\u021bire, adic\u0103 timpul necesar pentru ca titlul virusului s\u0103 scad\u0103 la jum\u0103tate. Viteza de descre\u0219tere ne d\u0103 o idee despre c\u00e2t de \"viabil\" este coronavirusul Covid-19 \u00een fiecare suprafa\u021b\u0103. Cu c\u00e2t mai pu\u021bin viabil, cu at\u00e2t mai bine.... pentru noi, nu pentru ei.<\/p>\n

Autorii raporteaz\u0103 testarea perioadei de \u00eenjum\u0103t\u0103\u021bire viabil\u0103 a virusului \u00een aerosoli (care imit\u0103 secre\u021bia spus\u0103 \u00een timpul unui str\u0103nut), \u00een cupru, carton, o\u021bel inoxidabil \u0219i plastic.<\/p>\n\n\n\n

\"Durata
Durata de via\u021b\u0103 a suprafe\u021bei coronavirusului Covid-19 \u00een aerosoli, cupru, carton, o\u021bel inoxidabil \u0219i plastic.<\/figcaption><\/figure>\n\n\n\n

Conform datelor raportate, coronavirusul Covid-19 a fost mai stabil pe plastic \u0219i o\u021bel inoxidabil dec\u00e2t pe cupru \u0219i carton, iar virusul viabil a fost detectat p\u00e2n\u0103 la 72 de ore dup\u0103 aplicarea pe aceste suprafe\u021be.<\/p>\n

Timpul de \u00eenjum\u0103t\u0103\u021bire al virusului viabil este de aproximativ 1h \u00een aerosoli sau \u00een cupru, de 3h \u00een carton \u0219i de peste 5h \u00een suprafe\u021be din o\u021bel inoxidabil \u0219i plastic.<\/p>\n

Concluzia este c\u0103 sticlele de plastic din frigider sau tac\u00e2murile pot fi cel mai bun loc pentru ca virusul s\u0103 se fixeze, dac\u0103 cineva din familie este contaminat asimptomatic \u0219i \u00eei infecteaz\u0103 pe ceilal\u021bi f\u0103r\u0103 s\u0103 \u0219tie. Cel mai bun sfat este s\u0103 nu mai \u00eemp\u0103r\u021bi\u021bi aceste obiecte cu ceilal\u021bi, doar pentru a fi \u00een siguran\u021b\u0103.<\/p>\n

O alt\u0103 concluzie care nu este evident\u0103 este c\u0103 punga de plastic din supermarket este probabil mai periculoas\u0103 dec\u00e2t cutia de carton pentru pizza de la curierul care o livreaz\u0103... este doar o presupunere, dar cred c\u0103 are sens.<\/p>\n\n\n\n

\"\"<\/p>\n

Pe suprafe\u021bele obi\u0219nuite utilizate pentru transportul obiectelor, coronavirusul Covid-19 nu r\u0103m\u00e2ne viabil dup\u0103 24 de ore. A\u0219adar, c\u00e2nd v\u0103 \u00eentoarce\u021bi de la b\u0103c\u0103nie, supermarket sau farmacie, ar putea fi util s\u0103 l\u0103sa\u021bi pungile (sau mai bine zis, cutiile) nesupravegheate pentru o zi \u0219i s\u0103 reveni\u021bi mai t\u00e2rziu. Probabil c\u0103 este mult mai sigur,\u0219i deosebit de util, dac\u0103 nu dori\u021bi s\u0103 purta\u021bi m\u0103nu\u0219i \u0219i s\u0103 cur\u0103\u021ba\u021bi fiecare articol adus acas\u0103.<\/p>\n

O alt\u0103 concluzie important\u0103 este c\u0103 coronavirusul Covid-19 se r\u0103sp\u00e2nde\u0219te probabil mai mult dec\u00e2t virusurile anterioare din aceea\u0219i clas\u0103, datorit\u0103 unor factori intrinseci naturii sale, inclusiv \u00eenc\u0103rc\u0103turile virale ridicate \u00een tractul respirator superior \u0219i poten\u021bialul persoanelor infectate cu SARS-CoV-2 de a r\u0103sp\u00e2ndi \u0219i transmite virusul \u00een timp ce sunt asimptomatice.  <\/p>\n

A\u0219adar, de\u0219i coronavirusul Covid-19 se lipe\u0219te de anumite suprafe\u021be, cel mai mare pericol este \u00een mod clar contactul direct cu persoanele contaminate. Coronavirusul nu r\u0103m\u00e2ne viabil pentru mult timp \u00een aerosoli, dar uneori, fiind aproape de cineva, este suficient. Fi\u021bi aten\u021bi la persoana care tu\u0219e\u0219te f\u0103r\u0103 masc\u0103 \u0219i nu v\u0103 apropia\u021bi pentru a o \u00eentreba dac\u0103 a fost testat\u0103 pozitiv. Nu conteaz\u0103, mai bine s\u0103 fie \u00een siguran\u021b\u0103 \u0219i s\u0103 practice izolarea social\u0103 pentru a preveni transmiterea coronavirusului<\/a>. Bine?<\/p>\n
