Covid: Brace yourself--lots of big changes this week!
CDC data and reporting:
See https://www.cdc.gov/mmwr/volumes/72/wr/mm7219e1.htm#T1_down for details.
With the end of the Public Health Emergency, the CDC is drastically reducing the data it collects and reports. As of May 11, 2023:
--COVID Data Tracker will display hospital admissions, deaths, and emergency department visits data as primary surveillance metrics for COVID-19.
--test positivity data from COVID-19 Electronic Laboratory Reporting has been removed from COVID Data Tracker and archived at healthdata.gov. After May 11, the National Respiratory and Enteric Virus Surveillance System will become CDC’s new source for testing data.
--COVID Data Tracker is no longer reporting aggregate cases and deaths, COVID-19 Community Levels, COVID-19 Community Transmission Levels, or COVID-19 Electronic Laboratory Reporting (CELR) data.

Using percentage-of-deaths-in-region as a metric for thinking about a preventable illness is absurd even leaving aside all of the risks from "mild" Covid cases.
It might readily be distorted by a rise in other deaths (e.g., guns, drunk driving) and look falsely low.
~ ~ ~
The CDC has stopped tracking community levels of Covid and the percentage of tests that come back positive, a metric used to calculate transmission rates,
To track death rates, agency officials now will rely on the National Vital Statistics System, which is highly accurate but tends to lag behind other kinds of surveillance by two to three weeks. The C.D.C. is also scaling back the data that hospitals are required to report, including the number of cases and the race, sex and age of patients. But the agency will continue to track overall Covid hospitalizations and intensive care admissions.
The data the C.D.C. still plans to collect will not provide enough actionable information at the state and local level, said Sam Scarpino, a public health expert at Northeastern University....
Collecting and reporting Covid data to the C.D.C. is time-consuming and laborious for many states and local jurisdictions, and some have already stopped doing so, limiting efforts to track the spread of the virus.
Some states are forbidden by their own laws from sharing data with the C.D.C. in the absence of an emergency.

“What we have right now is not a national public health system,” said Nirav Shah, the CDC’s principal deputy director. “We have a patchwork. And as a result of that, when we want to get data and synthesize it, it takes a lot of legwork that takes way too long.”
It’s up to states to decide what kind of data and how often to report to the CDC.
states control their responses to emerging infectious diseases, with state laws dictating how health data is collected and shared.

Sleep Apnea increases Long Covid
Past studies have shown that patients with obstructive sleep apnea (OSA) tend to have more severe illness when initially infected with COVID-19. OSA affects about 1 in 8 adults but is often underdiagnosed...
Published in the journal Sleep, this study found that a prior diagnosis of sleep apnea in the PCORnet group came with a 12 percent increase in risk for long-term symptoms months after patients' initial infections.

Masking:
Mass General retracted their "Patients can't ask for masking" statement, replacing it with "Patients can ask, but providers determine when and if masking in a clinical situation is necessary."

How much ventilation is enough? CDC updates recommendations
CDC now recommends aiming for 5 air changes per hour (ACH).
NOTE: ASRAE's new recs are generally higher than CDC's recs. (see Devices)
This and other updates on Ventilation in Buildings at cdc.gov/coronavirus/20 /1
Enhanced strategies in plain language at cdc.gov/coronavirus/20:
1. Aim for 5 ACH
2. Upgrade filters to MERV13
3. Turn HVAC to ON when occupied
4. More outdoor air (open windows, exhaust fans)
5. Use air cleaners
6. Germicidal UV
7. CO2 sensor (<800 ppm)
(For more on this, see devices section)

RSV: We finally have a vaccine for this deadly virus
The vaccine, named Arexvy, will be given to people 60 years and older.
Globally, RSV is estimated to cause one in every 50 deaths in children under five.
RSV is harder to diagnose in older adults but may be more common than influenza. It can develop into conditions such as pneumonia, which can be fatal. Globally, at least 300,000 people over 65 are ill enough to be admitted to hospital with an RSV infection each year, around 4% of whom will die.
The vaccine gave 83% protection against lower respiratory tract disease caused by RSV.

Elderly with few antibodies may need an extra dose of COVID-19 vaccine: Study
The new mRNA vaccines have just as good a protective effect against COVID-19 for the very oldest as for younger people. This is evident in a study at Umeå University, where researchers have followed individuals in special housing around Sweden. However, the study shows that elderly people with a low antibody response after vaccination were at increased risk of dying from the omicron variants of the disease. The research is published in The Lancet Regional Health—Europe.

Oxygen therapy found to improve heart function in patients with long COVID
A small randomized trial in patients with post-COVID syndrome has found that hyperbaric oxygen therapy promotes restoration of the heart's ability to contract properly. The research is presented at EACVI 2023, a scientific congress of the European Society of Cardiology (ESC).

Moderna beats Pfizer among two-dose COVID vaccine recipients aged 60 and over, study shows
The mRNA COVID-19 vaccines developed by Pfizer and Moderna continue to save lives. But a new paper published in the journal Vaccines provides evidence that the two vaccines are not equivalent when it comes to protecting older adults against death.
[Note: Moderna is also a higher dose of vax]

What’s Long COVID look like at 2 years?
Devices, Masks, and Ventilation:
ASHRAE Control of Infectious Aerosols - Equivalent Outdoor Air Rates
The new standard is out and can be found here. osr.ashrae.org/default.aspx
(NOTE: These are generally higher than CDC's recs of only 5 air exchanges. See NEWS)
The recommended equivalent outdoor air rates can be found in Table 5-1 on page 4. They are overall very high. For reference, WHO recommends 10 litres per second (lps)/person and OSPE and Lancet recommend 13.5 lps/person.

Tips, general reading for public:
Ventilate.
Mask.
Vax.

In this photo is Audrey Hepburn with Otto Frank, Anne’s father. Audrey Hepburn was born on May 4, 1929. The actress is best known for such films as Roman Holiday and Breakfast at Tiffany’s, but did you know that she turned down playing the role of Anne Frank? Here’s why. What many may not know about Hepburn is that as a teenager she helped the Dutch resistance in WWII. Both Hepburn and Frank were born in 1929. The two never met but Hepburn felt close to the young diarist, and lived 60 miles apart from each other. While Hepburn was not Jewish, she spent several years of the war in a cellar to use as a bomb shelter and even faced near starvation. During this time she managed to arrange illegal dance performances to support local families who were hiding Jews. After the war, Otto reached out to Hepburn asking if she would play the role of his daughter for the movie adaptation of the well-known diary. Hepburn felt unable to play the part, having had such a traumatic experience during the war, it would be too difficult. She said of Frank: “It’s a little bit as if this had happened to my sister . . . in a way she was my soul sister.” Photo: Luca Dotti

Alessandra Korap Munduruku, 39, has been awarded this year's Goldman Prize, which recognises grassroots activism.
Her vocal campaign to protect the Munduruku territory saw her confronting mining giant Anglo American.
As a result, Anglo American withdrew 27 research applications to mine inside indigenous territories...
Asked by the BBC if she found the prospect of taking on the mining giant daunting, Alessandra Korap Munduruku said that she had derived strength from the territory she aimed to protect.
"It [Anglo American] may be powerful to you, but to me, the powerful ones are the river, the strength of our territory and our people, the ant doing its work and the resistance of our people for more than 500 years in the fight for our land."
