Apple Watch predicted #COVID19 in healthcare workers ~1 week before positive PCR test confirmation, says new study from Mount Sinai researchers. 🧵
techcrunch.com/2021/02/09/mou…
2) dubbed the “Warrior Watch Study,” it used a dedicated Apple Watch and iPhone app and participants from Mount Sinai staff. It required participants to use the app for health data monitoring & collection, & fill out daily survey on potential COVID-19 symptoms and other factors.
3) During the study, the research team enlisted “several hundred healthcare workers” to participate, and collected data over several months, between April and September. The primary biometric signal that the study’s authors were watching was heart rate variability (HRV),
4) which is a key indicator of strain on a person’s nervous system. This information was combined with information around reported symptoms associated with COVID-19, including fever, aches, dry cough, gastrointestinal issues, and loss of taste and smell, among others.

📍This is all our future if we don’t stop the #B117 variant worldwide. I cannot stress enough —#B117 is here and can spawn a new fresh pandemic wave in April if we don’t act.

Alberta 🇨🇦 is a tip of the iceberg. Germany 🇩🇪 is seeing #B117 surge, Denmark 🇩🇰, Florida, & more.
2) And yes, the more infectious #B117 in Florida. And it’s growing fast. Already 10% if all cases. See 🧵
3) Florida is on a bad pace for domination by #B117 earlier than any other state.

BREAKING—new Biden announcement, “Just this afternoon we signed final contracts for 100 million more Moderna & 100 million more Pfizer vaccines.”

Also, 100 million previously slated for late June will now be delivered in late May!! #COVID19 #COVIDVaccine
2) We are on a good pace at 1.5 mil a day. But we need to hit 3 million to stay ahead of #B117 variant. bloomberg.com/graphics/covid… Image
3) Globally, US has done 14 shot per 100 people. Good. But Israel 🇮🇱 is at 65 already. Image

JUST ONE PERSON—UK 🇬🇧 scientists think one immunocompromised person who cleared virus slowly & only partially wiped out an infection, leaving behind genetically-hardier viruses that rebound & learn how to survive better. That’s likely how #B117 started. 🧵 wired.co.uk/article/chroni… Image
2) The leading hypothesis is that the new variant evolved within just one person, chronically infected with the virus for so long it was able to evolve into a new, more infectious form.

same thing happened in Boston in another immunocompromised person that was sick for 155 days.
3) What happened in Boston with one 45 year old man who was highly infectious for 155 days straight before he died... is exactly what scientists think happened in Kent, England that gave rise to #B117.

Behold... a #ZeroCovid utopia without any #COVID19, no variants, no vaccine or syringe shortages, no mask wars, kids in schools, & people just having fun!

It’s all possible if we aim for full suppression, and not just half-ass mitigation. We can do this.
2) We can go there.... if we don’t get complacent about a rising #B117 surge under us. Don’t let up.
3) If you want that utopia world like New Zealand, then damnit, double mask or switch to tight fitting premium mask. ?

Behold... a #ZeroCovid utopia without any #COVID19, no variants, no drug or vaccine or syringe shortage crises, no mask wars, kids in schools, and people just having fun...

It’s all possible if we aim for full suppression, and not just half-ass mitigation. We can do this too.
2) And yes we can go there. But we can’t get complacent when we know a #B117 surge is brewing. We can’t be relaxing too much.
3) If you want that utopia world like New Zealand, then damnit, double mask or switch to tight fitting premium mask.

⚠️Concerning—new data shows the more contagious #B117 variant is growing so quickly in Florida—now almost 10% of all #COVID19 case. California only ~2 weeks behind. Surge of #B117 may yield April wave if vaccine rollout slow. 🧵

2) Florida on pace for early March when #B117 passes >50% & dominant. Study by @K_G_Andersen put it at ~March 9th, with ~9 day doubling time.

#B117 is 38-49% more transmissible in Florida, but 40-60% more transmissible according to UK 🇬🇧 data. Image
3) Nationwide, doubling time is ~10 days and with an estimated data it becomes >50% dominant around March 23rd. medrxiv.org/content/10.110… ImageImage
