Half of kids in a California classroom tested positive for Covid after unmasked and unvaccinated teacher came into school while symptomatic with the Indian 'Delta' variant, CDC report finds

"Half of students in a California classroom tested positive for COVID-19 after a teacher came into school while infected with the Indian 'Delta' variant, a new Centers for Disease Control and Prevention (CDC) report finds."

"Within one week, 12 of the 24 pupils in the class were confirmed to be infected with the virus - seven of whom sat in the front two rows."

"The positive results came despite the desks being placed six feet apart and the children wearing masks while indoors."

"What's more, all classrooms were equipped with portable high-efficiency particulate (HEPA) air filters, and doors and windows were left open."

You postted a propaganda filled “news” article, not a CDC report. Get your facts straight and quit trying to push a false narrative. It is highly irresponsible.

this irresponsible teacher super spreaders it to the children who had ZERO natural immunity as no human on earth before exposure to a novel virus has natural immunity.

Did you forget that parents' genes are replicated in their children, including t-cell immunity 'memory'? Your ASSumption that none of the parents had immunity from SARS-1, which is 79% similar to CoVID-2, and is showing immunity against the 'delta variant' to be better than the 'jabbed'?

How manny 'vaccinated' teacher / spreaders are walking around that school spewing CoVID-delta?

If they can't identify the Delta variant through testing, how can they say this teacher had it?

"Coming to school with symptoms of a contagious disease is grounds for termination."

Sorry, no termination for teachers.. No matter what.! Union rules..

Don't make yourself look like such a total idiot. Try reading more than a headline. For example, see my comment on the article in the first post:

Forcing kids to wear masks is a waste of time, as the parents of all of these children have learned

And then read post #3 in the thread which says:

The original CDC report is here.

What false narrative do you think I am pushing? Do you think putting masks on school kids that do nothing to protect them is a good idea? Do you personally believe the kind of cloth masks the kids are forced to wear can stop an aerosol virus?

Do you think the CDC report I posted isn't the one the article is based on?

Define the "false narrative" so we can all learn.

Lab procedures exist to determine the DNA or RNA sequences of a virus. They aren't used for ordinary screening, but they are used in research situations, or investigations like this one. The CDC report I linked to in post #3 describes what they did:

Specimens for WGS were collected during May 26–June 12; all 18 positive specimens with detectable virus (cycle threshold value <32) were sequenced using ClearDx instruments (Clear Laboratories), Oxford Nanopore MinION sequencing technology, and SARS-CoV-2 ARTIC V3 protocol for amplicon sequencing.† Consensus genome assembly was performed in Terra using Titan Clear Laboratories workflow.§ All sequences generated were classified as the Delta variant. A phylogenetic tree was constructed using the UShER pipeline and visualized using Auspice.us¶ (4) (Figure 3). Eleven sequences were genetically indistinguishable from one another; seven sequences contained additional single nucleotide variations. Among the indistinguishable specimens, six were from students of the index patient, four were from students in the separate grade, and one was from a sibling of a student in the index patient’s class, suggesting that infections occurring in the two grades likely were part of the same outbreak.

So they detected the virus using the normal PCR test, notably with less than 32 PCR cycles, and then they sequenced the viruses. That lets them determine ancestor descendant relationships in the same way DNA sequencing is used to identify human offspring or relatives.

That is how the CDC determined that the teacher had the Delta variant.

But the more important point of this article is unchanged regardless of what COVID variant the teacher had, or really if they even had COVID at all. The important point is that masks on kids in elementary schools don't do anything to stop airborne viruses from spreading. That experimentally determined result from this classroom should by itself end all mandates for kids to wear masks in classrooms.

However, a person really doesn’t have to be a genius to understand the CDC when they say that they are unable to distinguish between ‘rona and flu.

Maybe you took your course in molecular genetics before sequencing was developed. But wouldn't the sequences done by the CDC pretty definitively identify COVID-19 vs. an influenza virus?

From the CDC report.

I would think so, but we’re not talking about sequencing. We’re talking about the PCR test, which is not suitable for that. Here’s something I found:

The fact that a primer works for PCR does not ensure that it will work for sequencing. PCR reactions are exponential and can use newly created product as template. Sequencing is linear and creates many fragments of different sizes. They are not the same thing.

Everybody has been using the PCR, not full-bore, time-consuming, expensive sequencing. And that is what the CDC has admitted does not work.

Except in this case, where the CDC did sequencing, as you can see from their report.

If true, and I believe very little of anything the CDC says, it does nothing to correct the months and months of falsified data they have released.

Further, everyone continues to use the PCR, which does not distinguish between ‘rona and flu.

The best boss I ever had was FAR ahead of his time [this was in 1990]:
"Don't drag your illness in to work. I don't want to catch what you have."


Yup, some of us are lucky. Most aren't. My old boss (before the lockdowns killed all our business, and he had to cut everyone) didn't track PTO. If you were sick and needed the day off, he preferred you stay home. If you needed it off for whatever, he was fine as long as you didn't abuse it, and we didn't have a big show you were needed on. Unfortunately, most companies don;t do that, especially as you get into bigger ones with more established policies and procedures and less personal the whole company is.

My boss had made himself indispensable [IT department head, and a great one], so he could go toe-to-toe with The Powers That Be.

Just talked with him today.

He can still break 80 at 75 years old.   ROFL face

I love that guy.

Define the “false narrative” so we can all learn.”

Below is actually what the CDC says, not the lies you spew...

“What is added by this report?

During May 23–June 12, 2021, 26 laboratory-confirmed COVID-19 cases occurred among Marin County, California, elementary school students and their contacts following exposure to an unvaccinated infected teacher. The attack rate in one affected classroom was 50%; risk correlated with seating proximity to the teacher.

What are the implications for public health practice?

Vaccines are effective against the Delta variant, but transmission risk remains elevated among unvaccinated persons in schools. In addition to vaccination, strict adherence to multiple nonpharmaceutical prevention strategies, including masking, are important to ensure safe school instruction.”

The attack rate in one affected classroom was 50%; risk correlated with seating proximity to the teacher.

And each of those kids was wearing a mask at all times during the exposure which lead to their infection. Since, as the report notes, infection risk was correlated with proximity, and hence exposure, the masks clearly failed.

You are smart enough to know that right?

The CDC report clearly establishes that the masks being worn by the kids in the classroom failed to prevent their infection.

You should also know that other CDC reports show that vaccinated people can shed the virus at high rates. So an infected, vaccinated teacher in the same situation would, according to the CDC, expel similar amounts of virus particles.

You still haven't succeeded in showing anything that refutes my simple point - the masks being worn by the kids did not protect them from infection. In fact you just presented quotes from the CDC report that show that the CDC themselves found the same thing. Otherwise their would not be infected kids with an infection rate correlating to distance from the teacher.

I see this as a positive. Covid transmitted to the younger population that is much more likely to resist / survive. Allows for the development of immunity that exceeds that provided by the vaccine. Kind of like a chicken pox party.

That is probably true. The only downside is spread from kids to other higher risk people.

Straight from the CDC...you can distort your mind, but don’t try to distort, mislead, lie to other people...
