“NO MORE THAN MERE SECONDS” of exposure in 10-60 centimeters where one man triggers several #DeltaVariant infections with brief “fleeting” contact. Thousands of shoppers at NSW🇦🇺 mass tested. Delta called “near & present danger”.

HT @lizziepearl. #COVID19
2) he “brushed past a man” in his 50’s… who became case #4. Ummm, wow. 👀 Image
3) Like geez, we know #DeltaVariant is basically the fastest transmitting variant to date. But this kind of “fleeting contact” infection is all the more reason for masks and improved ventilation and air disinfection.
4) NSW health minister Brad Hazzard said the Delta variant which is behind this outbreak is a “near and present danger” given the fleeting contact between cases at the Bondi Junction Westfield.

google.com/amp/s/amp.theg…
5) ““It is fair to say that this Delta virus would appear to be a near and present danger to anybody who is in the vicinity,” he said.”
6) Cmon, must be have a one time random event. Right? Wrong! ➡️ “It is the second “fleeting contact” transmission connected to the first case. A woman in her 70s was sitting outside a cafe that the initial case had visited and genomic sequencing of her virus is an exact match” ⚠️ Image
7) No way you say???? Lordy, I hope there’s tapes you say???…. Well guess what, this other fleeting contact case with the woman was **caught on security cameras” of a store. “They never came into contact” at all.
8) Anchor: “they just passed each other in the department store” ⚠️ (see video above)

“This obviously caused some concern” by NSW 🇦🇺 health authorities. Image
9) I think it’s safe to say #DeltaVariant is now the greatest threat of #COVID19 pandemic in 2021. It is by far the fastest variant known to date. The data complied from 64 countries by @WHO don’t lie. #B16172 is a clear and present danger to the world.
10) #DeltaVariant was formerly known as the “Indian variant” before the new Greek names established. In India, it was estimated by @IHME_UW that there were 13-14 million NEW infections PER DAY during its peak. Let that sink in.
11) We’ve also seen how #DeltaVariant has efficiently infected millions in India 🇮🇳 and likely killed ~1.6 million people (estimates by Economist and NYT range from 600,000-4 mil). Let that sink in. That’s mostly from #B16172 - aka Delta. Don’t let this happen to the world. Image
12) The numbers too staggering? You don’t believe it? Well here is NYT’s analysis. @IHME_UW also estimated over 1 million conservatively as well. This is the same #DeltaVariant now infecting the world. Take it seriously please. And tell your local leaders.
nytimes.com/interactive/20…
13) Why act now? Because #DeltaVariant is soaring across multiple countries of the world. It’s all but certain to dominate the US and continental Europe soon too. Even the head of WHO Europe region admits it.
14) Good news is vaccines mostly work against #DeltaVariant, albeit attenuated (below is the average of AZ and Pfizer vaccines, though 2 dose AZ efficacy itself is actually 60%, not 80%, while Pfizer is 88%). But bad news is 1 dose efficacy is only 30-33%—very poor. Need 2 doses.
15) that said, the #DeltaVariant is trouble. let this sink in - #DeltaVariant is still penetrating for vaccine breakthroughs that 10% of all hospitalized #COVID19 cases in last week was among those with 2 dose + 14 days fully vaccinated (and UK is majority AZ vaccinated)
16) “Dr Jenny Harries, the chief executive of the UK Health Security Agency, urged people eligible for vaccination to come forward to receive the jab.
“vaccination is our best defence,” she said, noting two doses provided significantly more protection than a single dose….
17) As Dr Fauci warned recently: “The problem you get into … is that a single dose only provides about ~30% effectiveness [against #DeltaVariant]—so that is really an issue you gotta be careful”, as Fauci tells @nehakhanna_07.

18) 2 doses much better than 1. But one dose only modestly better than none against #DeltaVariant. We need 2 doses for everyone ASAP. Fauci and UK leaders all recognize this.
19) #DeltaVariant is also exponentially growing in distant Alberta 🇨🇦. delta is now everywhere on every continent on Earth. It’s just that infectious.
20) please sign this petition to CDC for urgent #DeltaVariant action. It is by @endCOVID19 & @CovidActionGrp and a “coalition of scientists, public health officials, epidemiologists, health care workers, educators, advocates, parents, & concerned citizens: change.org/p/centers-for-…
21) UPDATE: multiple new locations of exposures added due to more newly uncovered casual contact cases from the same outbreak in NSW. #DeltaVariant is just that contagious. 9news.com.au/national/coron…
22) Mad respect to the NSW public health govt officials. They have now published the full exhaustive list of “casual contact” locations in which every case has been - with precise time and location for each. Wowzers on the comprehensive contact tracing.

health.nsw.gov.au/Infectious/cov… Image
23) Many of you are asking about changing vaccine types amid #DeltaVariant. It’s a tricky topic but many countries are now allowing it. Canada for example…
24) P.s. is this why Australia 🇦🇺 contact tracing to find fleeting exposure infections is so darn good?
25) Welp… Australia acting finally seriously. But it may be too little too late.

⚠️Bad signal—CDC confirming—“cats having neurologic symptoms, rapid decline, and death” from H5N1 #birdflu. 3 more cases in cats 🐈 on dairy farms… now 6 total. ➡️The prior 3 bird flu positive cats? All dead now. Likely more. This is mammalian adaptation.
bnonews.com/index.php/2024…

2) I suspect cats are drinking milk from the dairy cows on the dairy farms. This is why we shouldn’t drink raw milk 🥛 currently. Even pasteurized milk, some scientists are unsure of because of lack of safety data. See thread 🧵 below.
3) Not just cats — certain dog breeds (like beagles are highly susceptible to H5N1 avian flu too. And such dogs can facilitate their adaptation towards humans eventually (since more dogs are around people than dairy cows).

📍Let this sink in—a world leading virologist @RickABright who has studied H5N1 bird flu says he is pausing all his milk consumption until he sees proof from both FDA & USDA that pasteurized milk is safe to drink. Pausing milk because of his concern over lack of transparent data.
Why are scientists pausing milk intake? Because there still isn’t enough data on safety of pasteurized milk. There has been data on other viruses in the past that survive pasteurization. See detailed thread 🧵 below.
3) also avoid raw and undercooked eggs for now just to be safe…

Testing conducted by the FDA on pasteurized commercially purchased milk has found genetic evidence of the H5N1 bird flu virus. ➡️But the testing, done by PCR cannot distinguish between live virus or fragments of viruses that could have been killed by the pasteurization process.

The FDA said it has been trying to see if it could grow virus from milk found to contain evidence of H5N1, which is the gold standard test to see if there is viable virus in a product. 📌The FDA *does NOT explicitly say FDA laboratories were unable to find live virus in the milk samples, but nevertheless it does state that its belief that commercial, pasteurized milk is safe to consume has not been altered by these findings.

(Sound familiar? Just like blanket assuming a virus “isn’t airborne”, “cannot transmit without symptoms”, “no human to human transmission” errors during COVID). That said, I will am hopeful that no live virus will be found in confirmation. But let’s be precautious.

2) PPE and safety googles or face shield recommended for dairy farmers and anyone handling raw milk 🥛. Also they warn about poor fitting respirators for children (who may work near dairy— like I used to help on a dairy farm as a kid in rural Pa). Image
3) people working with cattle 🐄 should also “avoid eating drinking smoking chewing gum in contaminated areas or touching eyes.” And people exposed should wear PPE should be monitored for symptoms for 10 days. Image

📈Measles epidemic trajectory is worsening in the U.S.—it has NOT flattened as some claimed. The surge continues—comparison of newest versus recent outbreak graph. Majority are unvaccinated, but there’s enough unvaccinated in many clusters for outbreaks.
cnn.com/health/measles…

Image
Image
2) here is another way to visualize the measles epidemic. Another annoying thing is that although 95% not double vaccinated, 5% of the previous 113 cases were vaccinated— which means that there is waning immunity or vaccine breakthrough with sufficiently big outbreak possible.
3) I specifically wanted about this issue that pockets of unvaccinated could still trigger outbreaks, and vaccine breakthroughs possible due to vaccine waning & if surrounded by pockets of low vaccinations. See my warning oped below. 👇

🐄—"Experts fear that H5N1 avian flu… may have been transmitted through a type of cattle feed called “poultry litter”—mix of poultry poop, spilled feed, feathers, and other waste scraped from the floors of industrial chicken and turkey production plants."
telegraph.co.uk/global-health/…
Europe does not allow cattle to be fed poultry feed. US does. This helps explain why US is seeing a cow outbreak of avian flu.
3) CDC warns against chicken and bird exposures and direct contact with poop. Yet why the hell are we feeding cattle poultry litter??? Corporate farms are so stupid and greedy.

Global CO2 levels and temperatures. But but but we scientists are merely “fear mongering” according to deniers. How about just facing reality? How about precautionary warnings to protect human lives?

@ed_hawkins @MrMatthewTodd #climatecrisis Image
Oh this seems totally fine.

I think we are screwed at this point on limiting temperature rise by 1.5 C. It’ll still take a miracle to avoid 2 C.
