⚠️Confirmed—#DeltaVariant is by far the *most contagious** variant found to date, with a transmissibility that is ~2x faster than older strain. #P1 is 2nd fastest, says @WHO study.🧵

#CoronavirusUpdate 2021/6/1🇫🇷仏AFPが新型コロナ変異株のファクトファイルを公開。これまでの変異株をWHO指定の呼称「アルファ」「ベータ」「ガンマ」…で表記。興味深いことに #B16171 「カパ」についてはそこから派生した #B16172 を「デルタ」と表記。これではすぐに24字を使い果たしそうだ。
📍My god… the upgraded warning #B16172 variant (magenta) is surging so fast. Epidemiologists now estimate it is 60% faster than even #B117 UK/Kent variant, which is already 50% faster. If true, it could make it fastest transmission one to be found worldwide. Thread 🧵. #COVID19
2) #B1672 has become quite dominant in India 🇮🇳 sequenced samples in @GISAID data. And it is projected to take over further by June. Figure from @TWenseleers.
Some say it could be due to sampling, but Tom doesn’t think so because #B16171 wouldn’t be selectively withheld.

3) @TWenseleers used his methods from earlier paper to estimate the new #B16172 transmission being 60% fast than the U.K. Kent #B117 variant.
#B16171 variant is 6.8-fold less susceptible to neutralization by sera from infection & vaccinated (Pfizer & Moderna) subjects. Despite this, most of the sera from convalescents (79%) & all from vaccinated subjects were still able to neutralize the variant biorxiv.org/content/10.110…
#Covaxin retains efficacy against #B1617: Only minimal reductions in the neutralization observed against B1617; Neutralization reduction by a factor of 1.95 & 1.8 was observed against the B1617 variant for B1 (D614G) & B117 variant, respectively. biorxiv.org/content/10.110…
#B16171 variant is highly pathogenic in hamsters than B1 (D614G) variant! B1617 demonstrates higher pathogenicity evident with reduced body weight, higher viral load in lungs & pronounced lung lesions as compared to B1 biorxiv.org/content/10.110…
