I think you misunderstood me. I mean your house is still plenty dirty since you're not constantly disinfecting it because of COVID-19. Public spaces may be more disinfected, and you might wash your hands more often outside, but you're still carrying around your normal bacteria from your filthy house.

Also, because hospital staff are wearing more PPE and the hospital itself is getting disinfected more often, there's fewer hospital bacteria in general and they're less likely to leave the hospital.

Yes, hospitals generally have fewer bacteria. But that's actually the cause of the problem. Because of the intense disinfecting efforts in hospitals, the number of the normal bacteria is low, while the drug-resistant ones survive just fine. So hospitals are filled with super bugs (drug resistant bacteria and yeast). Yes, there are many ways to clean surfaces, high temperature, bleach, alcohol, soap, etc. However, many equipment in hospitals simply cannot be cleaned effectively. You can't push an entire MRI into an autoclave machine and you can't take it apart to clean it since it will take weeks and highly trained professionals and tons of calibration to get it back to work. So it is impossible to clean much of the equipment in hospitals.

When I first started my lab, I used antibiotics in all water baths and everything containing liquid to make sure that we don't get contaminated. However, a senior faculty told me not to use antibiotics. He said, with no antibiotics, if I get contaminations, it's most likely a normal bacteria. I can clean them off easily. With too much antibiotics, if I get contaminations, it will be most certainly a super bug. By that time, the only thing I can do is to throw away everything I own in the lab. There is no way I can clean off the super bugs.

So don't make a habit of going to hospitals...

There is an investigation in Germany that contains an indication that a part of the population has protective T cells in their blood due to previous colds.

This could be a reason that Covid-19 causes more harm where colds are less common. This could also be a reason why children who catch cold more often get Covid-19 less often.

The clues will be examined further.

I'm not so sure about that. T-cells are very specific to the particular viruses. The T-cells left from a previous flu are very specific to that strain of flu. They are useless to even other strains, let alone other types of viruses. I always want to compare our immune system to a locksmith. T-cells are like keys, while each type/strain of viruses is like a unique lock. I have a dozen of keys in my pocket. Does that mean I can open the lock of your house? This is also why people say that, even if/when we get a vaccine for the Coronavirus, it will lose effects when the virus will mutate too much. Each T-cell has a single unique kind of antibody decorating the cell surface, and the cell swims around looking for targets. If this antibody cannot find any target within a period of time, the entire T-cell will be sent for suicide (apoptosis). As soon as a type of antibody finds a target, the key and the lock, well, lock in and send signals to start replicating the same type of T-cells. Then our immune system kicks into a high gear and starts manufacturing the exact same kind of T-cells. After the whole thing blows over, a small amount of this particular type of T-cells is kept in a vault in case we see the same kind of virus again. that's how a small amount of T-cells is left from a previous flu. So I don't see how these T-cells specifically for the flu can be of any use for COVID-19.

Thanks for sharing the article! This is an interesting study, but not surprising. T-cells in COVID-19 patients are more capable of recognizing the unique features of SARS-CoV-2, while T-cells in a small portion of healthy donors (34%) can only recognize the parts of SARS-CoV-2 that resemble flu virus. T-cells of only a very small fraction of the healthy donors (8.8%) can recognize the unique features of SARS-CoV-2. So this is not surprising that healthy donors contain some T-cells that can recognize some features commonly shared between SARS-CoV-2 and flu virus.

The more important assay they did was the last one, where they tested how the functions of these T-cells respond to the viral features. They show that the T-cells from COVID-19 patients respond effectively to the presence of the unique SARS-CoV-2 parts, suggesting that these cells become fully functional.

They then tested the T-cells from healthy donors who recognize the unique features of SARS-CoV-2 (that slim 8.8% of the healthy donors). Interestingly, they show that the functions of these T-cells do not fully respond to the unique SARS-CoV-2 parts, albeit they can recognize these parts.

Although they discussed the potential implications of common cold, their findings directly show that only those COVID-19 patients possess capability to recognize and functionally respond to new SARS-CoV-2 infection. Healthy donors can only recognize some features commonly shared by SARS-CoV-2 and flu, and simply cannot functionally respond to new SARS-CoV-2 infection. This is consistent with our traditional understanding of how our immune system works.

Here is a more detailed report of the news.

CNBG, the vaccine development subsidiary of China's pharmaceutical giant SinoPharm, is moving along very well. The company has two vaccines (both inactivated) under human trial. The one from her other subsidiary Beijing Institute of Biological Products also completed Phase I/II trial in May with very positive result (see Post 6410 in this thread).

US didn't just "not promote" face masks, they flat out said it doesn't work if you don't have COVID. They think masks are just Chinese trying to rip them off and reduce their freedom, everything is just more US mental masturbation.

Why not just tell people to make their own masks or something.

What is the CDC guideline?
Does the CDC guideline state anyone with Coronavirus, should go out their daily lives and should wear a mask only when they are within 6 feet?
This is a total retard guideline or Congressman Tom Rice is the retard. Which is it? Either way, the guideline is either faulty or is not being properly disseminated.

Rep. Tom Rice, a South Carolina Republican, announced on Monday that he, his wife, and his son had been infected with the coronavirus. But just two weeks ago, Rice appeared on the House floor in Washington without a face covering.

reporter Manu Raju asked Rice why he wasn't wearing a mask in the chamber on May 28, the congressman said he could maintain at least 6 feet of distance from everyone on the floor and in the halls of the Capitol and therefore didn't need to wear a mask. COVID-19 can spread even from asymptomatic carriers.

"I do wear it sometimes on the floor," he told Raju in May. "I make an effort to ... stay 6 feet away from folks in accordance with guidelines. And when I'm forced into a situation where I can't do that — like on a plane — I do wear a mask."

The Centers for Disease Control and Prevention recommends everyone wear a cloth face covering when they cannot maintain at least 6 feet of distance from others.
