Nuovo Virus Cinese

[LucaTs]

Ho letto che si riaprirebbero dal 15 luglio.
Comunque, qua non hanno ancora riaperto tutti i ristoranti

No, ci sono deroghe per le regione. Il FVG ha scelto autonomamente per la riapertura del 19 giugno

Experiment suggests coronavirus has evolved to more easily infect human cells

From CNN’s Maggie Fox
Researchers in Florida said they believe their experiment has shown that the new coronavirus has mutated in a way that makes it more easily to infect human cells.
They said more research is needed to show whether this changes how the virus infects people, and whether the change has affected the course of the pandemic. But at least one researcher not involved in the study said it likely has done so, and the changes may explain why the virus has caused so many infections in the United States and Latin America.
The scientists at the Scripps Research Institute in Florida said the mutation affect the spike protein – a structure on the outside of the virus that it uses to get into cells. If the findings are confirmed, it would the first time someone has demonstrated the virus has changed in a significant way.
“Viruses with this mutation were much more infectious than those without the mutation in the cell culture system we used,” Scripps Research virologist Hyeryun Choe, who helped lead the study, said in a statement.
Just this week, the World Health Organization said the mutations seen so far in the new coronavirus had not made it more easily transmissible, nor had they made the virus more likely to cause serious illness.
Choe and colleagues ran a series of experiments in lab dishes that show a mutation called D614G gives the virus many more spikes, which in turn make it easier for it to get into cells. They’ve published their findings on a preprint server called BioRxiv. That means the work has not been reviewed by other experts in the field.
But Choe and colleagues did send their paper to William Haseltine, a virologist, biotechnology entrepreneur and chairman of Access Health International. Haseltine believes the findings explain the easy spread of coronavirus across the Americas.
“It is significant because it shows the virus can change, does change to its advantage and possibly to our disadvantage,” he told CNN. “It has done a good job so far of adapting to human culture.”

Ottimo @burian br ,grazie ,intanto segnalo Individuato a Modena il meccanismo immunologico alla base della vasculite da Covid-19. È la prima volta al mondo - Quotidiano Sanità

Grazie Morriz!

Non capisco i termini medici, ma vasculite la manifestazione principale della Kawasaki nei bambini, interessante.
Come potrebbe essere collegata la cosa?

Nel caso in questione della ricerca, alla base vi è l'attivazione del complemento. Il complemento è una via proteica che rientra nella risposta immunitaria. E' attivata da anticorpi quando questi si legano alle proteine virali (ma non solo), e lo scopo è distruggere le cellule infettate dal virus per eliminare con esse anche le particelle virali al loro interno.

Tuttavia l'attivazione può avvenire anche contro strutture sane in presenza di eccessiva risposta immunitaria, ed è questo il caso della vasculite.

Eh sì, e quello è il virus diffusosi per primo in Italia

[burian br]

Ieri in USA meno morti (+791 vs +904 dell'altro ieri) ma molti più casi (hanno superato per la prima volta da tre settimane i +27mila, con +27.221 positivi)

Ma hanno eseguito 720k tamponi

se non fosse anche questa, delle discoteche, una questione puramente economica, come tutte le altre riaperture necessarie a far ripartire l'economia, proprio le discoteche non le avrei riaperte per adesso, ma avrei aspettato
ma si sa: siccome anche questo settore sta risentendo pesantemente, come tanti altri, perciò...si riaprono anche le discoteche....
del resto, abbiamo aperto tutto ormai

Come detto tante volte, ok le discoteche se rimangono chiuse, alcune rischiano di chiudere per sempre.
Ma perché non usarle (per un bel po') come luogo per fare gli spettacoli (stando a distanza con le sedie ovviamente) oppure come pub? Penso sia l'unico metodo

Però, Simo, tolte ER Lombardia e Piemonte e il Lazio (focolaio ospedaliero), il resto del Paese è sostanzialmente fuori dall'epidemia: 30 casi totali in 16 regioni. Manco 2 per regione di media

Lo era anche Pechino...
