The scariest thing to take from that is that our lives are in the hands of someone called DJ Darwin R. Bandoy.

If enough get infected the virus might get enough variation to produce multiple strains running simulatiously across the world, and no one will know if their previous brush with the disease has given them immunity to the next one they happen to run into.morepork wrote:canta_brian wrote:Will that make immunity to any strain pointless against the next version?morepork wrote:Antigenic drift.

I wouldn't say pointless. The immediate issue is a range of antigens are going to have to be considered to account for variation. Like a seasonal flu vaccine.

And still the UK shows no interest in contact tracing (even in the absence of tests this can be done for those showing symptoms). Betting everything on herd immunity or a magic vaccine.
Good, although a lot hinges on what your "soon" means.morepork wrote:Easy Plath. Herd immunity with such an unknown quantity such as this particular virus is too big a gamble. The vaccine thing however, will materialise at some stage soon. The genome of this virus has already been sequenced, and once the most antigenic viral proteins encoded for by that sequence are documented, a vaccine will be forthcoming. Again, like influenza, small gradual changes in the coronavirus genome will produce subtle changes in antigen amino acid content and maybe structure. That's why we get a cold more than once in our lifetimes. In practice this means a vaccine based on a specific part of a single viral antigen may be rendered ineffective because the antibodies raised by vaccination are not correctly targeted to changes in the actual antigen in the current viral population. The antigen is still a legitimate target for a vaccine, but the vaccine will have to be tweaked occasionally in response to changes in the viral genome. This is done every year for the flu.Son of Mathonwy wrote:If enough get infected the virus might get enough variation to produce multiple strains running simulatiously across the world, and no one will know if their previous brush with the disease has given them immunity to the next one they happen to run into.morepork wrote:

Sure, we will always need vaccines, but we didn't need one for SARs.morepork wrote:We will always need vaccines chief. We are stuck with them now. This won't be the last global public health crisis caused by a virus.
I wouldn't like to label anyone suicidal, just saying a bit of optimism tempered with a pinch of cynicism would be the way to go.

Latest graph on death rates. There seems little correlation with more stringent social distancing equalling a shallower line. If anything the two best European performers have the loosest rules in place. One thing you can say is that the US is in deep do-do.
I don’t disagree with you. Was just pointing out that there is no correlation at this point. Both Sweden and Holland are behind most others so far too early to take anything from it.morepork wrote:Mellsblue wrote:Some good news coming out of Italy as numbers in ICU drop for the first time.

I’m going to call you out on that one. It is a virus transmissible by close contact. Distance is the best possible way to avoid transmission. The data at the end of the day will bear this out.

I’ve read a couple of bits that domestic arrangements may explain severity of spread. Italy have multigenerational living arrangements whilst Sweden has the most single occupation homes per capita in Europe.
Which is why the Scottish CMO's cockup was quite so huge, by setting such an authoritative example of "fuck it, I'll do what I wanna"morepork wrote: That just reinforces distancing as an effective response. Italy has tourist attractions that are respectfully more superficially attractive than tulips and Ace of Base. The virus was brought in to Italy by human traffic. Likewise, New York is one of the worlds great urban hubs, with vast numbers of domestic and international tourists. That is why it is an epicenter now. De Moines Iowa has fewer cases than NYC for this very reason, but if New Yorkers get an urge to sit this out and attend a celebration of corn event in Iowa, then De Moines is thrust into the infection front row.
yes, or I made it up for the fun of it?- and its more a shocking failure of the NHS to distribute it properly. Its been stockpiled and not drawn down. There's a warehouse full near me. The centralisation of critical resources has been one of the standout stupidity moments, combined with the inability to inject urgency.morepork wrote:Italy have been chasing shadows. They have reacted after an event probably initiated by one of those floating Petri dish cruise ships in Somewhere like Venice. They have been triaging rather than containing. The model for track and trace remains South Korea and Taiwan. Unlike these two places, Italy did not have the benefits of the SARS drill to hone a response.
Banquo, is this true:
There is plenty of PPE out there, its just stuck in the NHS supply chain, and a lot in the wrong places- the non London Trusts have a lot of spare stock for example.
If so, that is a shocking failure of market philosophy in a public health setting.
Holland is pretty bad actually.Mellsblue wrote:I don’t disagree with you. Was just pointing out that there is no correlation at this point.

great call. Deal with the dozy twats day in day out. The talented clinicians tend to stay on or near the front line- the rest are promoted to the level of their own incompetence, and then sit alongside the MBA's- their talents are fine for climbing the greasy pole- essentially over promise and then blame someone else- but sh&t for this serious stuff.morepork wrote:All hail the MBA.
