Re: New Variant Covid-19 VUI 202012/01
There's a prediction that the English variant could become the dominant one in Italy within 5-6 weeks and that there are more cases amongst young people
(currently 17.8% of the cases are the variant)

The local news says it's more like 30% here in Lombardy. (R is only just less than 1 here, but at a look at the numbers suggests that this week cases stopped going down and have started to go up.)

Updated NERVTAG report on the variant of concern: https://assets.publishing.service.gov.u ... 210211.pdf
More evidence that it’s more lethal, and is associated with more serious illness.

Ricciardi, the one who'd rather just lock everything down, says that the variant arrived in Europe via Swiss ski resorts.

Hence the unpopular decision taken at the last moment yesterday to keep the skilifts closed here for another few weeks instead of opening them today.

Mean duration of infection of 13.3 days vs 8.2 days for the old type.For individuals infected with B.1.1.7, the mean duration of the proliferation phase was 5.3 days (90% credible interval [2.7, 7.8]), the mean duration of the clearance phase was 8.0 days [6.1, 9.9], and the mean overall duration of infection (proliferation plus clearance) was 13.3 days [10.1, 16.5]. These compare to a mean proliferation phase of 2.0 days [0.7, 3.3], a mean clearance phase of 6.2 days [5.1, 7.1], and a mean duration of infection of 8.2 days [6.5, 9.7] for non-B.1.1.7 virus
Rather unfortunate that on December 14th the UK reduced its self-isolation period from 14 to 10 days.

Re: New Variant Covid-19 VUI 202012/01
From an evolutionary perspective this is what you'd expect. The virus and what was left of the patient's immune system were in near-equilibrium so there would be a strong selective pressure for mutations that tilted the balance.Woodchopper wrote: ↑Wed Feb 10, 2021 8:40 pmAnother report of the virus evolving during a long term infection of one person.
