VIRUS RESURGING, and it's not even winter yet: after crushing the curve, France🇫🇷/Spain🇪🇸 recording more cases than during prior peak. Consequence of ill-prepared reopening, travel, spread among youth, bar-goers...In some place ICUs almost at saturation: wapo.st/3ck8qgl🧵
In the meantime, as Israel's cases soar, it became the first country to enter into a second lockdown. With some hospitals at capacity and turning patients away, the military is stepping in to set up field hospitals: bit.ly/3kBoTj7 2/4
Iran🇮🇷is in trouble: Among earliest to be hit, now in its 3rd wave. Each wave's baseline worse than last. Iran also coming off holiday travel & inadequate masking:bit.ly/2EmFuI5
“We no longer have orange and yellow, the whole country is in red" - Dep. Health Minister 3/4
Everyone needs to have a plan and prepare for the winter months. Without precautions, spending more time indoors, often in crowded and poorly ventilated spaces, will exacerbate the pandemic 4/4 theatlantic.com/health/archive…

2/The outbreak was driven by human-to-human transmission via close contact with infected persons; most cases among men who have sex with men.
However: the new study (albeit small sample size) points to infection from contact with skin lesions as higher risk than from semen.
3/Researchers looked at Mpox G2R-mRNA activity which is an indicator of replicating virus. They found high activity (more virus replication) in lesions, but much lower activity (in some cases non existent) in semen, suggesting that this biologic fluid could represent minor route.
A thread on how Paxlovid💊neutralizes the virus👇 1/5
2/The SARS-CoV-2 virus is made up of components (proteins, RNA, lipids) that come together and give rise to functional virus particles. Paxlovid blocks the ability of some of the proteins to function, resulting in a defective virus. Here's how…
3/Normally, when the virus infects cells, its RNA genome replicates, the RNA is turned into proteins, & proteins come together to make new viruses.
When the proteins are made, they're initially strung together, but they need to be freed from one another in order to do their job
Electric Vehicle battery & grid battery supply chains are coming to the USA 🇺🇸
$2.8 Billion in awards to support 20 companies to manufacture domestically
This is 1st of set of investments to build out battery manufacturing

Albemarle: project objective to construct new, commercial-scale U.S.-
based lithium materials processing plant at Kings Mountain, North
Carolina that uses sustainably extracted minerals from the site’s lithium mine.

American Battery Technology Company: commercial-scale facility to manufacture battery cathode lithium hydroxide from Nevada-based lithium-bearing sedimentary resources.
The Inflation Reduction Act Congress just passed includes a historic $369 billion investment to 1) lower energy costs; 2) revitalize US manufacturing; 3) slash greenhouse gasses by 40%; and 4) address environmental justice. Here are a few highlights from this bill🧵
1. Lowers energy costs for consumers:
Includes rebates to install electric & low emission appliances in homes
Also includes tax credits to make homes energy efficient, install solar, geothermal, etc...
$7,500 consumer credit to purchase clean cars like EVs; $4K for used🚘
2. Supports nationwide clean energy manufacturing base
Tax credits for manufacturers of clean energy technologies
Grants and loans so auto makers can retool & produce clean cars, like Electric Vehicles
Funds R&D @ENERGY National Labs to develop next-gen energy technologies
1/Early diagnosis, isolation & contact tracing of close contacts are key to controling the Monkeypox outbreak.
Here are the European Union health authority's recommendations for who should be contact traced during this outbreak: the four categories of "close contacts" include:🧵
2/
🔹️Sexual partners: those with any type of sexual contact with MPX cases from the onset of symptoms
🔹️Household contacts: those living in same household (inc. overnight camping/stay) with MPX cases; those sharing clothing, bedding, utensils; or caregivers of MPX cases
3/
🔹️Health workers coming into contact w/patient's lesions or w/prolonged face-to-face contact (>3 hrs at < 2m distance) or involved w/aerosol generating procedures—all without PPE
🔹️Other: case-by-case, may include those sitting next to MPX case during prolonged travel
1/Monkeypox is a member of the Poxviridae family. These are large viruses with large DNA genomes (∼200 thousand bases🧬). By comparison, sars-cov-2 has ~30 thousand. And since its genome is made of RNA it mutates more than monkeypox. Nice review article:rb.gy/higk98🧵
2/Monkeypox is closely related to the infamous smallpox. After smallpox was eradicated through a global vaccination campaign we rightly stopped vaccinating against it. But that allowed monkeypox, once confined to remote areas, to spread more.
3/While the monkeypox case fatality is lower than smallpox—which had a whopping 30% case fatality—monkeypox is quite serious and lethal. Historically the Central African clade had a 10.6% fatality, while the West African clade was 3.6%. The latter has spread around the world.
