O nou\u0103 estimare a cercet\u0103torilor de la Institutele Na\u021bionale de S\u0103n\u0103tate \u0219i de la Universitatea din Pennsylvania au ar\u0103tat c\u0103 vorbitul tare timp de un minut genereaz\u0103 cel pu\u021bin 1000 de astfel de particule care con\u021bin coronavirus, relateaz\u0103 CNN.<\/p>\n

Aceste pic\u0103turi r\u0103m\u00e2n \u00een aer timp de peste opt minute, conform unui studiu publicat mar\u021bi \u00een jurnalul \u0219tiin\u021bific PNAS. Conform cercet\u0103rii, este suficient ca o persoan\u0103 s\u0103n\u0103toas\u0103 s\u0103 inhaleze aceste particule pentru ca ea s\u0103 se infecteze cu noul coronavirus.<\/p>\n

Pentru a realiza experimentul, cercet\u0103torii au cerut unei persoane s\u0103 repete cuvintele \u201eR\u0103m\u00e2i s\u0103n\u0103tos!\u201d, \u00eentr-un spa\u021biu care simuleaz\u0103 un mediu cu aer stagnant. Fraza a fost aleas\u0103, spun cercet\u0103torii, pentru c\u0103 grupul de cuvinte \u201eth\u201d, \u00een limba englez\u0103, din cuv\u00e2ntul \u201ehealthy\u201d, genereaz\u0103 astfel de pic\u0103turi de saliv\u0103.<\/p>\n

Cercet\u0103torii au folosit, apoi, un laser pentru a observa ce se \u00eent\u00e2mpl\u0103 cu aceste particule dup\u0103 ce ele au p\u0103r\u0103sit cavitatea bucal\u0103. Rezultatul a fost c\u0103 pic\u0103turile mari s-au mic\u0219orat \u0219i evaporat \u00een aer, \u00eens\u0103 au r\u0103mas \u00een aer timp de peste opt minute. Inhalarea unor astfel de particule infectate de c\u0103tre o persoan\u0103 s\u0103n\u0103toas\u0103 duce la r\u0103sp\u00e2ndirea bolii.<\/p>\n
