UK variant update:

50% more contagious and the main difference is in the rate of infection in children up to the age of 9.

No significant difference found yet in clinical course, mortality within 28 days or chance of re-infection.

50% higher infection rate

(Secondary attack rate 15.1% versus 9.8%)

Main effect in children under 9 years old

(see age distributions, second image has overlay of reference onto UK variant)

Essential to stop the UK variant: 50% higher transmission will lead to more cases, more hospitalizations, more ICU cases, more deaths, and greater economic costs.

1)Accelerate vaccinations
2)Control: a) Advance application for travel to and from the UK, a negative PCR test prior to travel, managed isolation on arrival b) Schools should remain closed until buildings are made as safe as possible for pupils and staff
c)Universities online

6/
3) test,trace,isolate: a)Test, b)Trace contacts as quickly as possible, isolate before they can infect others. Include forward tracing (identifying who you might have infected) and backwards tracing (who infected you), c)Practical support to isolate

7/
4) Provide guidance for workplace safety.
5) Provide financial support for the public.

Compare
👉higher fatality, with
👉increase in transmissibility ON fatality.

Example:
50% higher fatality increases deaths from 129 to 193.
50% higher transmissibility increases from 129 to 978 after one month, more if longer

The idea behind this study is that future hydrogen demand is highly uncertain and we don’t want to spend tens of billions of euros to repurpose a network which won’t be needed. For instance, hydrogen in ground transport is a hotly debated topic

Similar things can be said about heat. 40% of today’s industrial natural gas use in the EU goes to heat below 100°C and therefore is within range of electric heat pumps – whose performance factors far exceed 100%. (3/17)


Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500°C). (4/17)


In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)

Even asymptomatic, previously called healthy, people are tested (en masse) in this way, although there is no epidemiologically relevant asymptomatic transmission. This means that even healthy people are declared as COVID
