Delta variant fears coming true—@WHO_Europe director says #DeltaVariant of #COVID19 is "poised to take hold"—#B16172 evades 1-dose vaccine & “shows increased transmissibility & some immune escape” & more severe. It is exponentially ⬆️ in 🇬🇧 & 🇺🇸 too.🧵

2) Hans Henri Kluge expressed concern about the Delta variant, known by the scientific name B.1.617.2, pointing to recent research appearing to show it can spread quickly and infect those who have received one of two vaccine doses at higher rates than the fully vaccinated.
3) "We have been here before."

"Over the course of last summer, cases gradually rose in younger age groups and then moved into older age groups, contributing to a devastating resurgence, lockdowns and loss of life in autumn and winter of 2020. Let's not make that mistake again."
4) The U.K. has determined that the Delta strain is the dominant variant in the country, overtaking the Alpha variant, also known as B.1.1.7. The surge is prominent among 12- to 20-year-olds, the U.S.'s top infectious disease expert, Anthony Fauci, said earlier in the week.
5) Here is the full story on how #DeltaVariant invaded UK, which allowed it to take hold first in Europe.
6) As result, UK is now abandoning its original June 21 reopening plan because of the rapid surge in #DeltaVariant and hospitalizations. Video part 2:
7) What do we want least of all? Lockdowns. How do we avoid it? These 6 urgent steps now! Video part 3.
8) And is it surging across many parts of the US? Yes. Fastest growing. Exponentially. See thread 🧵 on 🇺🇸 spread…
9) And is it just cases ⬆️? No, it’s hospitalizations surging too across parts of UK 🇬🇧
10) 📍Outbreak even w/ 2 dose of mRNA vaccines—🇨🇦 hospital—16 patients & 6 healthcare staff #DeltaVariant positive. 6/16 patients & 5/6 HCWs had received 2 doses of #COVID19 vaccine; 7 patients & 1 healthcare worker had 1 dose. 1 patient now in ICU.

📍1 in 4–almost a quarter of people infected develop at least one lingering health problem after 30 days with #COVID19. The most common included pain, breathing trouble, high cholesterol, malaise and/or fatigue and high blood pressure. 🧵 google.com/amp/s/time.com…
2) But the reported post-COVID symptoms were quite varied, running the gamut from depression and anxiety to skin conditions to heart issues and gastrointestinal distress.
3) most Long COVID symptoms are more commonly reported by women than men.

Health analyzed private health care claim records for nearly 2 million people diagnosed with COVID-19 in 2020. The people in the study ranged in age from babies to the elderly;

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

2) This comes on the heels of the urgent advocacy by many to demand CDC upgrade to VOC. Even WHO and UK 🇬🇧 raised #DeltaVariant to VOC weeks ago. CDC is very late on this.
3) We have known #DeltaVariant has been rising fast in the Us for quite a while. Over a week ago, we already knew it was exponentially rising across the US. It’s doubling every 2 weeks overall, but doubling every week in certain states.

⚠️New CDC warning on rising RSV again. Coincided with dropping of mask mandates & usage. ➡️ “The CDC is issuing this health advisory to notify clinicians and caregivers about increased interseasonal respiratory syncytial virus (RSV) activity across parts of the Southern US.” 🧵
2) CDC: “Due to this increased activity, CDC encourages broader testing for RSV among patients presenting with acute respiratory illness who test negative for SARS-CoV-2, the virus that causes COVID-19. RSV can be associated with severe disease in young children and older adults”
3) “RSV is the most common cause of bronchiolitis and pneumonia in children under one year of age in the United States. Infants, young children, and older adults with chronic medical conditions are at risk of severe disease from RSV infection.

So, vaccines good against hospitalizations, yes, but not when just 1 dose against #DeltaVariant, not when <50% fully vaxxed. Despite new controversial case-control efficacy study (very small & assumption laden)—🇬🇧hospital #COVID19 surges just don’t lie.🧵 assets.publishing.service.gov.uk/government/upl…
2) Note how much weaker 1 dose is versus 2 doses for the #DeltaVariant for both infection and hospitalization.
3) What is the first clue the new controversial study is unreliable? The Pfizer 2 dose results aren’t even significant due to wide 95% CIs. Second, the 1 dose is stronger than 2 dose for Pfizer? Hog wash. We know that’s not true and opposite. This is why this study unreliable.

Masks are coming off—the cold and flu is now back. Coincidence? No. The CDC just issued a health advisory about increased cases of respiratory syncytial virus, or RSV, across parts of the southern US — something CDC hadn’t seen since April 2020. #MaskOn

2) RSV is a cold-like respiratory illness that produces symptoms similar to COVID, and can cause severe illness in older adults and young children. It disappeared for a year because of #COVID19 mitigations. It’s now back because masks are coming off, especially in the South.
3) Since the state’s mask mandate was lifted at the end of May, face coverings have started to come off — and stay off. But according to infectious diseases doctors, the return of facial freedom might come with some downsides, like a resurgence in cases of the common cold and flu

⚠️Annoyed—the US CDC still does **not seem to classify the #DeltaVariant as a “Variant of Concern”**!! #B16172 is still merely “variant of interest” on @CDCgov website, updated just this weekend. Both @WHO & 🇬🇧 upgraded Delta to VOC weeks ago. CDC act now! cdc.gov/coronavirus/20…
2) Because this is what new cases of #DeltaVariant #COVID19 is doing in the UK 🇬🇧… US 🇺🇸 is a trouble if don’t act now
3) Is #DeltaVariant growing quickly in the Us? Yes. Hell yes. Yet CDC doesn’t rate it a VOC.
