Announcements:
First, there is now a Resources Page here for the most commonly asked questions I'm getting.
Happy to continue to answer your questions/concerns as best I can, so don't be shy about that.

Check out Field Team 6: MISSION:
Register Democrats.
Save the World.
I've just started text banking with them--they've automated much of it! Looking forward to exploring them further. They claim: Every $0.70 you donate helps us register one Democratic voter in a swing state. Compare that to the Obama re-elect campaign, who spent $150/voter.

COVID-19 survivors at higher risk for digestive diseases, study suggests
Adult COVID-19 survivors are at higher risk for digestive diseases, including gastrointestinal (GI) dysfunction, peptic ulcers, gastroesophageal reflux disease (GERD), gallbladder disease, nonalcoholic liver disease, and pancreatic disease—even among patients with mild infections, according to a study published yesterday in BMC Medicine.

Nearly two thirds of Korean SARS-Cov-2 cohort had long COVID at 2 years
Two years after COVID-19 infection, 62.0% of a South Korean cohort still had symptoms such as fatigue, memory loss, and depression, finds a study published today in Scientific Reports.

Brain aging:
“Covid can cause a reduction in grey matter and “ongoing brain damage” leading to cognitive decline the equivalent of 20 years ageing, new research with huge implications has just revealed”
Scores are compared to 2,927 matched normative community volunteers.
Cognitive deficits were associated with elevated brain injury biomarkers and reduced grey matter volume. The half-lives of the brain injury markers mean that this is objective evidence of *ongoing* brain injury one year after COVID-19. 4/n
Deficits were correlated with symptoms of depression and the anterior cingulate cortex volume, which has functional roles in connecting cognition, attention, and emotion 5/n
The severity of the initial infection, infection early in the pandemic, post-acute psychiatric symptoms and a history of encephalopathy were associated with greatest deficits. Importantly this means our findings don't generalised to COVID-19 today or mild respiratory disease 6/n
Treatment with corticosteroids during the acute phase appeared *protective* against post-acute cognitive deficits 7/n
There is growing biochemical evidence that neurological complications in COVID-19, including cognitive impairment, are immune-mediated which is corroborated here by clinical demonstration of the protective effect of acute treatment with corticosteroids 9/n

Benefit of eyeglasses in preventing infection
A total of 19,166 participants responded to the questionnaire, with 13,681 (71.3%, CI 70.7-72.0) reporting they wore eyeglasses. Multivariable logistic regression model showed a 15% lower odds of infection for those who reported using eyeglasses always for general use (odds ratio [OR] 0.85, 95% 0.77-0.95, P = 0.002) compared to those who never wore eyeglasses. The protective effect was reduced for those who said wearing eyeglasses interfered with mask-wearing and was absent for contact lens wearers.

Influenza:
RSV shown to infect nerve cells, cause inflammation and damage
Respiratory syncytial virus (RSV), a common infection in children and senior adults, can also infect nerve cells and trigger inflammation leading to nerve damage, according to a new Tulane University study.
RSV can cause mild symptoms such as coughing, sneezing and fever or lead to more severe conditions such as pneumonia or bronchiolitis. But since the disease was first discovered in 1956, it has been thought to only infect the respiratory tract.
This study, published in The Journal of Infectious Diseases, is the first to prove that RSV can penetrate nerve cells. It may provide the clearest link between RSV and reported neurological symptoms in children.

Diagnostics:
A new study showed that, during the Omicron era, viral load peaked (i.e., had low values in the graph below) on days 3-4. This is very different than the beginning of the pandemic when it peaked at the start of symptoms. (They also looked at the flu, which peaked on days 1-2.)
Why does this matter? You may not reliably test positive on a rapid antigen test until the third, fourth, or even fifth day of symptoms. This raises questions on how best to use tests, too, like with Paxlovid (which needs to be given within 5 days of symptoms) and isolation.

Michael Mina:
COVID tests take longer to turn positive after symptoms start But nothing changed w test ability to detect new virus What changed is we have existing immunity —> makes symptoms start v fast after exposure before the virus grows up

RAPID TESTS DO WORK WITH OMICRON
"But why are some people staying negative in the first days they have symptoms??"
This is expected. Symptoms don't = contagious virus
This is literally a reflection of the fact that vaccines are doing their job!

What are the recommendations for testing?
take a second Rapid Antigen Test (RAT) test 48 hours later. ...and another on Day 4...or get a PCR test.

Drugs and Vaccines:
Universal vaccine for Coronavirus?
What if scientists had developed a universal coronavirus vaccine in the years prior to 2020 so that it was available at the start of the COVID-19 pandemic? A universal coronavirus vaccine targets parts of the virus that are common to either many or all coronaviruses, thereby offering some degree of protection against a range of strains.
"COVID-19 was the third major and serious coronavirus epidemic or pandemic following SARS in 2002 and MERS in 2012, thus, we should anticipate a fourth coronavirus outbreak within the next decade or so," says Peter J. Hotez, MD, Ph.D. "A universal vaccine is cost-effective and cost-saving and a priority for advancement."
The travesty of not funding Corbevax...
Note: Texas Children’s Hospital and Baylor College of Medicine developed CORBEVAX™, a protein sub-unit COVID-19 Vaccine, which is used in India.
Dubbed “The World’s COVID-19 Vaccine”, it uses a traditional recombinant protein-based technology that will enable its production at large scales making it widely accessible to inoculate the global population. The initial construct and production process of the vaccine antigen was developed at Texas Children’s Hospital CVD, led by co-directors Drs. Maria Elena Bottazzi and Peter Hotez.
Their vaccine is patent free, open science, with no proprietary technology.
The vaccine formula can be licensed by a vaccine producer in any low- or middle-income nation, which would then take ownership of it, produce it, name it and work with the government to get it to the people, Hotez said.
Their vaccine uses the same recombinant protein technology already used for decades in the hepatitis B vaccine, a common childhood shot.
The vaccine technology has no intellectual property rights attached to it. That means the building blocks of the vaccine can be had for the price of a phone call. Once produced, the vaccine can be sold to governments for far less than any other vaccine currently on the market.
“Our intent was to make it available to millions of people in the world who would otherwise not have access to COVID vaccines,” said Hotez,
In 2020, the Houston team’s work was passed over for funding by Operation Warp Speed, Operation Warp Speed spent more than $12 billion in federal tax dollars to develop and distribute the vaccines launched by Pfizer, Moderna and Johnson & Johnson. The Corbevax formula is also not new — but unlike the mRNA shots, its recombinant protein technology has been in widespread use globally for decades.

Epidemiology/Infection control:
Transmission takes hours
New info: Transmission increased linearly by 1% chance per hour. Most transmission resulted from exposures lasting one hour to several days. Households accounted for 6% of contacts but 40% of transmissions.
Why does this matter? Transmission = time x proximity. This may help your risk calculations. Quick passersby at a grocery store are far less risky than staying in a house with someone infected.

SCOTUS will hear Johnson v Grants Pass, a case about if homeless people can be punished for using things like pillow and blankets when sleeping outside if there are no safe shelters. This is the biggest SCOTUS case about homelessness in decades.
the Johnson v. Grants Pass case says that "unless everybody has access to shelter that meets their needs, they cannot be arrested, ticketed, or otherwise punished for sleeping outside."

whether officials can jail or fine homeless people for sleeping outside.
