📍The coronavirus is airborne. Very airborne. Even if you don’t see anyone—doesn’t mean the aerosols aren’t in the air. WATCH📺

➡️ you need high quality N95 / KN95 / KF94 / FFP2/ FFP3 masks.

➡️ also please ventilate, get HEPA filters, get upper room UV.
2) VENTILATION is key. Both ventilation and masks needed to reduce risk indoors. But most buildings not ventilated well enough.

3) AEROSOLS ARE AIRBORNE.

“Until we recognise that #COVID19 is airborne we are setting ourselves up for repeated failure”
4) How is aerosol different from large droplets? aerosol study indicates that coronavirus is persistent and stable for many hours. Typical air exchange every 20 min to 4 hrs, depending on ventilation. #COVID19
5) Now that aerosol transmission of the coronavirus is established, we need to disperse aerosols quickly. Key is ventilation. 🇯🇵 assumed it was airborne from the beginning. Here is how to ventilate your school classrooms if unable to open window. #COVID19
6) One neat trick about masks… they are AGNOSTIC / DON’T CARE about which variant it is! #Omicron resilient! Cool eh? #MaskUp

7) not only is it airborne, but #Omicron also is 70x faster in viral replication in your windpipe! Seriously - any small dose could yield a much faster infection. 👇
8) Lots of blame to go around, but the IPC department of the WHO deserves a lot of blame according to aerosol expert @jljcolorado below 👇

9) Also, while airplanes do have good HEPA filters — they aren’t running when parked at the gate! And if you know how long delays and boarding time can be, I think this is a serious issue. People need to definitely masks on planes.
10) AIRBORNE transmission in a hotel — look 👀 how the virus floated across the hallways to two other rooms and cross infected them without any direct contact. We only know about it because of security cameras recoding brief door openings—that carried an wind 💨 draft. 👇

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.

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.

📍BIRD HUNTING AVIAN FLU DEATH—WHO reports that a 21 year old young man with no underlying conditions suddenly died of #avianflu in Vietnam. He started with a cough/fever, but died 12 days later with severe pneumonia and ARDS. ➡️He had only gone bird hunting recently. BE CAREFUL.

2) "From 2003 to 25 March 2024, a total of 888 worldwide human cases of influenza A(H5N1), 463 deaths (52% CFR), reported to WHO from 23 countries. Almost all cases of human infection with avian influenza A(H5N1) linked to close contact with infected live or dead birds, or contaminated environments."
who.int/emergencies/di…
3) It is interesting that WHO had to point out he had no contact with any sick or dead birds. Only hunting. And he had gone bird hunting the prior month in Feb 2024. And no other contact with people since. The latency period seems rather long.

⚠️SPIKE IN MEASLES—113 cases of US measles in Q1 of 2024, double the total for all of 2023. 📍95% of the cases were in those without 2 full doses of MMR💉vaccine (83% cases without any confirmed shots). Across 18 states—top 2 states are Illinois & Florida. 58% of all cases got hospitalized🏥—66% of infected kids <5 years old hospitalized. 61% of adults 20+ hospitalized. Please take measles seriously. Don’t listen to RFK Jr.

2) Moreover, many of the nationwide cases had come from Florida— “Measles cases that turned up in at least three states this year were linked to visits to Florida, federal and state investigators concluded”. FL also doesn’t count non-residents as cases.🤦🏻‍♂️

3) I wrote a long WARNING last month about measles surging in the U.S. — we are not addressing the crisis. Florida measles crisis is just a bell weather. And now here we are.
