FROM MY NECK OF THE WOODS: Coronavirus in Tennessee: Knox County reports 77 COVID-19 cases, drive-thru testing coming. “Knox County reported a total of 77 on the health department website Wednesday, up from 63 reported on Tuesday. The number of recovered cases grew to 28. Twelve of the 77 cases have resulted in hospitalization at any point during the illness. This figure does not reflect the number of patients currently hospitalized in the county. . . . The KCHD is also declining to give additional condition information on those who have been hospitalized with the coronavirus since there are so few cases hospitalized with COVID-19.” Well, I’m glad we’re not seeing many in the hospitals yet.

POWERING SMART SENSOR NETWORKS with wireless waste energy. “The electricity that lights our homes and powers our appliances also creates small magnetic fields that are present all around us. Scientists have developed a new mechanism capable of harvesting this wasted magnetic field energy and converting it into enough electricity to power next-generation sensor networks for smart buildings and factories.”

PRIVACY: Two more macOS Zoom flaws surface, as lawsuit & government probe loom.

The second flaw, which is arguably more concerning, allows a local user or piece of malware to piggyback on Zoom’s camera and microphone permissions. An attacker can inject malicious code into Zoom’s process space and “inherit” camera and microphone permissions, allowing them to hijack them without a user’s knowledge.

While local exploits like these typically require physical access to a computer, they’re usually much more common and difficult to prevent should the rest of the criteria that are needed are fulfilled.

The class action, filed in the U.S. District Court for the Northern District of California, alleges that Zoom gave personal user information to third parties without being explicitly clear about the data-sharing practices, CBS News reported. New York Attorney General Letitia James has also launched a probe into Zoom’s privacy policies.

In a separate development, Zoom may also be inadvertently leaking user email addresses and photos to complete strangers, according to Motherboard.

It’s pretty safe to conclude that Zoom is Chinese spyware masquerading as a videoconferencing app.

FACEMASKS: Have we been asking the wrong question all along? Officials in the UK say face masks don’t protect us. In China they agree but wear them because they protect others.

Plus, bureaucracy at work:

It is a matter of orthodoxy at the UK Department of Health and Social Care (DHSC) that surgical facemasks are a no-no as far as the public are concerned. Officials have long taken the view that paper masks do not protect against viruses and do not hold emergency stocks of them.

That thinking, like so much else, is now being tested. On Tuesday, the US Centers for Disease Control (CDC) – a long standing ally of Whitehall in the no-mask camp – was reported to be about to change its advice. Surgical masks should be used, not for personal protection, but to protect others from Covid-19, it was expected to announce.

It’s another virus-fighting lesson that has been borrowed from the east and raises important questions. Might population-wide use of face masks have slowed the spread of the pandemic in the west? And were our public health officials asking the wrong question all along?

I first thought about face masks at around 4pm on Wednesday, November 28, 2007, when a small but agitated civil servant flung open the door of my office shouting, “Take it down! Take it down!”. I was editing the NHS website and we had just published a story which suggested that face masks had helped bring the 2003/4 Sars epidemic under control in south east Asia.

The official was part of the DHSC’s pandemic planning team. She was very angry and wanted the story taken down immediately. She had just been to see the then Prime Minister, Gordon Brown, and had explained to him, “in terms he could understand”, that there was really no need for the UK to hold a stockpile of masks, she said. The story we had just published threatened to undo all of that by giving credence to an “minor academic paper” which said the opposite. I told her to hop-off.

Good.

DUMB: 28 University of Texas Spring Breakers Who Flouted Health Advice Are Now Sick With Coronavirus. “About 70 students from the University of Texas at Austin, all in their 20s, chartered a plane to Cabo San Lucas, Mexico, in late March. They took the trip despite public health advice to avoid crowding as well as nonessential air travel. On Tuesday, Austin public health officials announced that 28 students, more than a third of the young people who took the trip, had returned and tested positive for the coronavirus. Many of the remaining students are under public health monitoring.”

FROM MICHIGAN, WHERE THE GOVERNOR JUST FLIP-FLOPPED FROM DENOUNCING THIS TREATMENT AS A TRUMP LIE TO DEMANDING THAT THE FEDS SHARE STOCKS OF THE DRUG: Henry Ford Health System uses hydroxychloroquine to treat COVID-19 symptoms, says benefits outweigh risks.

“We feel that there is data both from the early published studies as well as from our colleagues in China that have treated a number of patients to justify its use in the therapy of sicker patients that are hospitalized with coronavirus infection.”

Dr. Zervos says the goal of using hydroxychloroquine is to prevent patients with symptoms like shortness of breath and pneumonia from progressing further in their illness, and to get those patients already in an intensive care unit and on a ventilator off the ventilator earlier and out of the hospital.

“What we know about the drug now is that it does reduce viral shedding, you know, the amount of virus a person has, it’s lower. There have been studies from China to show that patients have shorter hospitalizations, fewer complications, lower likelihood of progression.”

It’s not the best drug imaginable, but it is the best drug available. They’re combining it with Azithromycin and also with Doxycycline.
