Bad news about the new UK variant
-
I definitely recall several months ago several articles that discussed a more infectious strain. I took interest in it wondering if it had a different mortality rate. Then, it disappeared from the news and now is back with a vengeance.
I agree it’s likely widespread by now.

@george-k said in Bad news about the new UK variant:
Evidence is that it's no more deadly than the other strains. But, if it's more infectious, that's not a good thing, to be sure.
Bach posted about a model showing that 50% higher R0 would result in more deaths than a 50% increase in IFR.
Makes sense, since death rate is linear and R0 is exponential.

To understand the difference between exponential and linear risks, consider an example put forth by Adam Kucharski, a professor at the London School of Hygiene & Tropical Medicine who focuses on mathematical analyses of infectious-disease outbreaks. Kucharski compares a 50 percent increase in virus lethality to a 50 percent increase in virus transmissibility. Take a virus reproduction rate of about 1.1 and an infection fatality risk of 0.8 percent and imagine 10,000 active infections—a plausible scenario for many European cities, as Kucharski notes. As things stand, with those numbers, we’d expect 129 deaths in a month. If the fatality rate increased by 50 percent, that would lead to 193 deaths. In contrast, a 50 percent increase in transmissibility would lead to a whopping 978 deaths in just one month—assuming, in both scenarios, a six-day infection-generation time.

Just came across this article about a mutation found in South Africa:

Anyone have more details?
