There is a new strain of #SARSCoV2 which is on the prowl in India. It is called #XBB1.16 and is highly transmissible. It has also been called #Arcutus. These are very early days for us to know the severity of the disease that can be caused by this variant. 
There are very important mutations in this variant which affect the immunity of the infected people. #INSACOG, #GISAID and #WHO confirmed the presence of new variant in India.
Last December, there was a slight increase in the number of cases when the Government has cautioned the state governments. I have asked the government not to worry except to monitor for new strains. Only if a new strain comes along, the disease dynamics will changes. XBB 1.5 was… twitter.com/i/web/status/1…
⚠️NEXT BIG ONE—CDC has royally screwed up—unreleased data shows #XBB15, a super variant, surged to 40% US (CDC unreported for weeks!) & now causing hospitalization surges in NY/NE.➡️XBB15–a new recombinant strain—is both more immune evasive & better at infecting than #BQ & XBB.🧵
2) Multiple models show #XBB15 is much worse in transmission R value and infection rate than previous variants — faster by LEAPS and BOUNDS. @JPWeiland did some the earliest models on #XBB15 watching data in NY. it has only grown worse nationwide.
3) in fact, when @JPWeiland first modeled #XBB15 before Xmas, the data shows XBB15 was 108% faster than the previously king #BQ1 variant. But with more data, XBB15 has further accelerated to now being 120% faster!
