Dall\u2019inizio della pandemia di COVID-19, gli scienziati hanno messo in guardia dal rischio di contrarre la malattia attraverso gli aerosol presenti nell\u2019aria. Ci\u00f2 ha portato anche all\u2019obbligo delle mascherine che obbligava tutti a indossare coperture per il viso nei luoghi pubblici.<\/p>\n

Tuttavia, un nuovo studio pubblicato su Il microbo lanceolato<\/a> hanno scoperto che gli aerosol non dovrebbero essere la preoccupazione principale di tutti coloro che sono bloccati in una famiglia con un paziente COVID-19. I ricercatori hanno recentemente scoperto che le superfici e le mani contaminate guidano le trasmissioni nelle case.<\/p>\n

Lo studio condotto dall\u2019Imperial College di Londra \u00e8 il primo a fornire prove empiriche della trasmissione di SARS-CoV-2, il virus responsabile del COVID-19, attraverso le superfici toccate frequentemente e le mani delle persone.<\/p>\n

\u201cNon c\u2019\u00e8 dubbio che se hai il COVID-19 emetti il virus nell\u2019aria sotto forma di micro-aerosol e di grandi goccioline che cadono sulle tue mani e sulla superficie intorno a te. Ci\u00f2 che non \u00e8 stato dimostrato, fino ad ora, \u00e8 che la presenza del virus sulle mani delle persone o sulle superfici domestiche predice la trasmissione ai contatti", ha detto l'autore principale Ajit Lalvani in uno studio. comunicato stampa<\/a>.<\/p>\n

\u201cIl nostro studio sulla vita reale nelle famiglie londinesi fornisce la prima prova empirica per dimostrare che la presenza di SARS-CoV-2 sulle mani e sulle superfici delle persone contribuisce in modo significativo alla diffusione di COVID-19. Dal momento che non abbiamo campionato sistematicamente l\u2019aria domestica, non possiamo escludere che la trasmissione aerea avvenga in parallelo\u201d.<\/p>\n

Per lo studio, Lalvani e colleghi hanno esaminato 279 famiglie londinesi durante il culmine delle onde alfa e pre-alfa della pandemia tra il 1 agosto 2020 e il 31 marzo 2021. Hanno scoperto che l\u2019infezione era significativamente pi\u00f9 alta nelle case in cui il virus \u00e8 stato rilevato sulle superfici toccate frequentemente e sulle mani dei partecipanti.<\/p>\n

\u201cLa presenza di RNA SARS-CoV-2 sulle mani dei casi primari e dei contatti e sulle superfici domestiche frequentemente toccate si associa alla trasmissione, identificandoli come potenziali vettori per la diffusione nelle famiglie\u201d, ha scritto il team.<\/p>\n

Per confermare che la trasmissione e l\u2019infezione sono avvenute all\u2019interno delle famiglie, i ricercatori hanno sequenziato l\u2019intero genoma dei 25 casi primari e dei loro contatti. Hanno scoperto che le coppie caso-contatto primarie avevano gli stessi ceppi virali.<\/p>\n

Tuttavia, Notizie dagli Stati Uniti e rapporto mondiale<\/a> ha sottolineato che lo studio era puramente osservazionale. Non \u00e8 stata dimostrata la causalit\u00e0 poich\u00e9 la trasmissione aerea non \u00e8 stata esclusa. Lo studio \u00e8 stato condotto anche durante la fase iniziale della pandemia, quindi non \u00e8 chiaro se gli stessi risultati si applicherebbero alle varianti pi\u00f9 recenti.<\/p>\n
