J. Harris: Not charted — Cases/100,000 pop. are still up in LA which is another good reason to stay in Texas.


“…In Britain, the spread of a new, highly contagious variant first detected in India has scrambled calculations just as the country planned to return to something more like prepandemic life on June 21…“The British are worrying more than any other country,” said Tim Spector, a professor of genetic epidemiology at King’s College London. “We seem to be much more receptive to the doomsday scenarios than they are in the U.S.”…A top scientific adviser to the British government estimated on Friday that the DELTA variant was roughly 60 percent more contagious than the earlier one from Britain. Health officials also warned that cases caused by the Delta variant might lead to a higher risk of hospitalization, though it was too early to say for certain….Since the Delta variant arrived in Britain in March, it has rapidly outspread other versions of the virus including the very contagious variant first identified in Britain [ALPHA], that contributed to deadly waves around the world this winter. That, in turn, has created localized outbreaks that have nudged Covid cases up.”

(J. Harris: Woops. So how effective are the vaccines against this Delta Covid virus? We need to find out now, before we are deluged with the variant by mutant infecting all of our unvaccinated folks.)

When will you need a Covid-19 booster shot?

“…Scientists have already found that vaccines using different technologies can vary in their effectiveness. The strongest vaccines include Moderna and Pfizer-BioNTech, both of which are based on RNA molecules. Vaccines relying on inactivated viruses, such as those made by Sinopharm in China and Bharat Biotech in India, have proved somewhat less effective… But at this point, scientists still have only a smattering of clues about how existing vaccines work against different variants.

COVID-19 Case Investigation and Contact Tracing in the US, 2020

“Conclusions and Relevance:  In this cross-sectional study of US local COVID-19 surveillance data, testing named contacts was a high-yield activity for case finding. However, this assessment suggests that contact tracing had suboptimal impact on SARS-CoV-2 transmission, largely because 2 of 3 cases were either not reached for interview or named no contacts when interviewed. These findings are relevant to decisions regarding the allocation of public health resources among the various prevention strategies and for the prioritization of case investigations and contact tracing efforts.”

Could Statins Do More Than Lower Cholesterol in Patients With COVID-19?

(J. Harris: Probably not, (“but not stop taking if you are on them, or start taking if you are not”)

National Nurses United ‘outraged’ over CDC’s rolled-back mask guidance

(J. Harris: It is hard to disagree with the troops in the trenches.)

Eased mask mandates haven’t fueled new COVID-19 cases, early data shows

(J. Harris: For vaccinated people not in a hospital or unsafe environment — however the wildcard remains the variants and the millions of Americans who are not vaccinated and the travelers.)

Scientists may have found a new coronavirus rapid-testing method: Bees

Conjoined twins walk into a bar in Canada and park themselves on a couple of bar stools.

  One of them says to the bartender, “Don’t mind us; we’re joined at the hip. I’m John, he’s Jim. Two Molson beers, draft please.”

The bartender, feeling slightly awkward, tries to make polite conversation while pouring the beers. “It’s been a tough year, and I’m glad that travel restrictions are loosening up.  Been on vacation yet, fellas?”

 “  Off to England next month,” says John. “We go to England every year, rent a car, and drive for days and days in the countryside, don’t we, Jim?”

  Jim nods.

   “Ah, England!” says the bartender. “Wonderful country…the history, the culture, and especially the beer.”

“Nah, we don’t like that British crap,” says John. “Hamburgers and Molson’s beer, that’s for us, eh Jim? And we can’t stand the English people, they’re so arrogant and rude.”

“So why keep going to England?” asks the bartender.

John replies: “Gives Jim a chance to drive…”
