    #DeltaVariant is causing this #COVID19 surge across all 50 US states—even in heavily vaccinated ones. Vaccines definitely work, but we have to dispel the notion that 1 shot for 70% is enough. We likely need 85%+ double vaccinated coverage with 2x more contagious Delta. Stay safe.pic.twitter.com/m0RqRH53A7

        2) the surge in #DeltaVariant is not surprising to anyone who has been paying attention. The @WHO even declared it a VOC in early may - yet the @CDCgov didn’t act to declare Delta a variant of concern until June 15th! Now we are here… ⬇️https://twitter.com/DrEricDing/status/1415524772260323334 …

        CDC says #DeltaVariant surging—now dominant ~58% of #COVID19 cases in US. Two weeks ago—31%. 6 weeks ago? Only 3%. Someone warned in May it would endanger the 🌎. Someone warned it will overtake US. Yet CDC didn’t declare Delta a VOC until June 15th. #DeltaVariant is no joke—🧵 pic.twitter.com/7599KyK3qa

        3) I’ve been trying to warn about #DeltaVariant since April (first for India) and May (for UK and other countries), and in early June calling out the early surge in the US. We should have taken urgent precautions when we see this trend already in 20 states…https://twitter.com/DrEricDing/status/1402062059890786311 …

        Troubling—the worst variant to date, the #DeltaVariant is now the new fastest growing variant in US. This is the so-called “Indian” variant #B16172 that is ravaging UK 🇬🇧 despite high vaccinations because it has immune evasion properties. Here is why it’s trouble—🧵. #COVID19 pic.twitter.com/nuPUOWoLa1

        4) After much nagging and cattle prodding, the CDC finally declared #DeltaVariant a VOC. I also want to point out **Delta is much more SEVERE than before**. Large studies from England & Scotland found 2.4-2.6x higher risk of hospitalization than Alpha—ergo 4x versus older strain.https://twitter.com/DrEricDing/status/1404847230205505550 …

        BREAKING—CDC now officially declares #DeltaVariant a “variant of concern”—because much more transmissible (50% faster than #B117, 2x than original strain), more severe (2.5x hospitalization risk than B117, 4x original) & 1 dose vaccine evasive.🧵 #COVID19 https://www.cdc.gov/coronavirus/2019-ncov/variants/variant-info.html … pic.twitter.com/SszvXuysze

        5) This is why we must take every effort to shield the vulnerable - including even if an elderly or immunocompromised person is fully vaccinated. There’s too many breakthrough cases, and efficacy against hospitalization is 93% instead of 98% (Israel data)https://twitter.com/drericding/status/1414358182982557697?s=21 …

        6) Besides the UK’s double study on #DeltaVariant severity being 2.5x worse than Alpha, ergo 4x worse than old strain, data from Singapore 🇸🇬 MOH found #DeltaVariant has a huge 4.9x higher risk of needing oxygen, hospitalization, or death than old strain—Delta is more severe! ⚠️https://twitter.com/DrEricDing/status/1414360616983220233 …

        8) Where is the evidence that #Delta is ~4x or more severe than old strain? There’s actually 3 studies. One key study from Singapore Ministry of Health actually found #DeltaVariant to have 4.9x higher odds of oxygen, hospital admission, or death! https://europepmc.org/article/ppr/ppr356279 … pic.twitter.com/hkBS6dD9qU

        7) Delta is more contagious and more severe partly due to the fact #DeltaVariant infected people have much much higher viral loads!!! This means more virus concentration in ones body and in what we release.https://twitter.com/DrEricDing/status/1414361968526364672 …

        Eric Feigl-DingVerified account @DrEricDing
        9) In this same study, the Singapore researchers found #DeltaVariant to have much higher viral load than other major strains. Thus, the higher severity is indeed very likely. Both lab and epidemiology supports it. This is also likely one reason why Delta is so transmissible too pic.twitter.com/VhKJmieD2F

        8) This is why Los Angeles absolutely did the right thing reinstating mask rules regardless of vaccination status. Vaccinated people can still transmit, and transmit quite a lot even if it’s less than unvaccinated. #MaskUphttps://twitter.com/DrEricDing/status/1415783040614375426 …

        BREAKING—With #COVID19 cases and hospitalizations surging, Los Angeles will now *require* indoor mask again, **regardless of vaccination status**. @CountyofLA’s mandate is what needs to be done to slow #DeltaVariant—where is our @CDCgov? @CDCDirector—please rules update ASAP. pic.twitter.com/9vxQJbANES

        9) “Pandemic of the unvaccinated” is a good description by @CDCDirector. However, I would add, it’s also a pandemic by people not masking, not taking airborne precautions, not ventilating, and still passing along the virus as well.https://twitter.com/Sky_Lee_1/status/1416448730274934785 …

        ⚠️Hospitalizations up 35.8% in just 1 week across the US from #COVID19, according to CDC. That graph is curving pretty sharply upward. All 50 states having rising cases—38 of 50 states seeing cases surging >50% in just 1 week. #DeltaVariant cannot be ignored. Vax + mask please.🧵 pic.twitter.com/oZCCjokvbC
