This paper by @devisridhar, @HelenClarkNZ, @martinmckee and others on how nine countries (incl. Germany) managed easing #covid19 restrictions is worth a close read. The take-aways may not be new, but they bear repeating:
thelancet.com/action/showPdf…
@devisridhar @HelenClarkNZ @martinmckee 1. "countries can move forward mainly on the basis of the epidemiology or on the epidemiology in combination with other considerations; however, a clear and transparent plan that describes which factors are being taken into account is essential”.
@devisridhar @HelenClarkNZ @martinmckee 2. “countries should not ease restrictions until they have robust systems in place to closely monitor the infection situation”.
@devisridhar @HelenClarkNZ @martinmckee 3. "continued measures to reduce transmission will be needed for some time … citizens should be directly involved in the process of coproducing tailored solutions appropriate for the local context"
@devisridhar @HelenClarkNZ @martinmckee 4. "each country should have an effective find, test, trace, isolate, and support system in place… needs to be supported by sustained investment in public-health capacity and health-system capacity in terms of facilities, supplies, and workforce"
@devisridhar @HelenClarkNZ @martinmckee And:
"We hope that countries will continue to share their experiences, information, and strategies as they respond to this virus that knows no borders."
#covid19 deaths in UK highest among residents of care homes, Black, Asian, and minority ethnic groups, socioeconomically deprived populations, workers on low wages. „These inequalities are likely to exist elsewhere, but in many countries, such as Germany, data are not collected.“

A thought on communication:
In today’s presser's opening statement @USDA presented work on killing H5N1 in ground beef through cooking. They mentioned no virus being present at 160°F and 145°F. Only later when someone asked, they mentioned that at 120°F there was some virus left.
@USDA I have thought a lot about trust and transparency in the wake of the #covid19 pandemic and to me this seems exactly the kind of communication style that does not build trust.
Yet another lesson not learnt in my book...
@USDA For reference, my thread on this:

Researchers at @USDA have done a “ground beef cooking study” to test at what temperature #H5N1 in meat is killed. To be clear: Tests have found no H5N1 in beef samples, so this was done “in the interest of scientific inquiry and to further reaffirm consumer confidence”
@USDA So researchers added #H5N1 to ground beef patties then cooked them:
“There was no virus present in the burgers cooked to 145° [Fahrhenheit] internal temperature, or roughly medium, or 160°, which equates with a well done burger, which is the recommended cooking temperature”
@USDA At lower temperatures, some virus survived. "Cooking to I believe it was 120° [Fahrenheit] did show that there was virus still in the cooked hamburger patty, although at much, much reduced levels."
(But remember that these were experimentally infected burgers.)

#h5n1 presser by @USDA and @HHSGov just ended. Had some some interesting bits (but what I would really love to see is still... serology):

With #H5N1 #birdflu spreading amongst dairy cows, one of the most important things to think about right now is what would need to happen for this virus to actually start a pandemic.
I'm on a train, so a brief thread...
One thing to remember is that compared to some other influenza viruses H5N1 actually faces pretty high barriers to becoming a human-to-human pathogen. I wrote a story a little over a year ago outlining some of the changes it would probably need: science.org/content/articl…
As @PeacockFlu told me at the time: H5 probably has one of the largest barriers to being a pandemic virus of any avian influenza virus. “It's really wrong in so many ways”, he told me.

The thing that most strikes me about the current #H5N1 #birdflu outbreak in cattle (and terrifies me to some extent) is how much the virus surprised us once again. And how cavalier our response seems in the face of that fact.
Remember that this is not a new virus. As Martin Beer, an expert on bovine viruses and on influenza, told me a few days ago: “This is not SARS-CoV-2. There is 27 years of research on this virus.” And yet…
He also told me that if someone had painted the exact scenario we are in right now a few months ago, his response would have been 'How do people come up with these crazy stories?'.

Stat’s @HelenBranswell talking about covid vaccine messaging and „The curse of the 95%“ now at @ESCMID #ECCMID2024 Image
Many scientists realized that expectations for a vaccine that is injected into the arm to prevent a respiratory infection were too high, she says, but the public was not prepared for this…

The comparison with flu is interesting, says @HelenBranswell: Not only was the model ignored in communicating about the covid19 vaccines but in the end the things that people in the US accept about flu vaccines are not accepted for covid19 vaccines… #ECCMID2024
