    It is also the 'approach' how people behave to get their informations.

    One wants to make an opinion about a special subject on corona. Origin, or why is it in Spain, Italy, NYC that heavy and South Korea, Germany not. Or whatever special subject such as the severity and mortality rate in general. What helps to prevent and what does not....etc etc...


    1. One has no opinion at all due to lack of info and wants to make an opinion. Therefore the one checks different sources (best with named author, institute, reputation). After the sources are spotted one compares them and relates them to local situations and conditions. This is a time consuming process, but sooner or later leads to an objective opinion. Or at least to an reasonable opinion and to knowledge.

    2. One has already a personal opinion (bias) and is looking for sources which do underline it or seem to underline it. The work is done when that source is found. Any further research on other sources does not happen. Different voices about are considered as a lie.

    Example here Germany:
    When the government announced the massive restrictions and has warned about corona such as :" We have not yet reached the peak of infection, the worst is not here yet. It can happen that our medical resources will run out" some people said that corona is not that dangerous, they want to patronize....

    Today where the infection rate is going down and the predicted worst case scenario did not happen (so far), they say: Ha! I was right!

    Others say: "The numbers coming from Germany must be fake. I don't believe that they have such a low mortality rate."

    Difference: The goal is to be right not to get the reasons behind!

    The more you test the lower the mortality rate. It is a statistical issue.

    (Even here scientists think there is an unknown infection rate of around 15%. This means 15% are not part of a statistic at all. They get the virus, stay at home with minor symptoms and go to work again).

    Source: https://www.pharmazeutische-zeitung.de/nur-15-prozent-der-corona-infektionen-werden-erkannt-116860/

    And those people do not know that we had luck (here are younger people affected compared to other nations). We reacted in an early state on it, we are testing a lot (350,000 tests /week) and tests are for free. We could learn from Italy, they are ahead.

    The medical staff is doing an extraordinary job, the medical infrastructure is best.
    Contrary to Italy the medical staff is constantly tested. Infections via medical staff did not happen.

    People have been isolated at once if they had contact to infected people. I was sent to quarantine when I came back from Thailand. I was not allowed to work. I was not tested, though. Precaution only.
    This sucked a lot for me, but that time there were not enough test kits available. I had no symptoms at all.

    Testing, tracing and reacting seems to be the success...

    But there were also mistakes...

    .... not to go massively after the super infections (for instance Ischgl). Paths of infections were not interrupted consequently.

    Well, I don't think it's the immune system alone. It depends mainly on pre-existing illness.
    It also seems SARS-CoV2 is far more contagious than SARS, but SARS had a mortality rate which was 10 times greater.

    As soon as there are antibody test studies we know how many people were really infected.
    All the restrictions are made to protect the people with higher risks and to provide best medical support for them.

    Coronavirus might spread much farther than 6 feet in the air....

    ALL internal links are on the page listed below bottom...

    Air contaminated with the COVID-19 virus might travel four times farther than the 6 feet the CDC asks we distance ourselves, according to a recent study.

    The study published in the Journal of the American Medical Association found that under the right conditions, liquid droplets from sneezes, coughs and just exhaling can travel more than 26 feet and linger in the air for minutes.

    Findings such as these may have some bearing on the CDC's recommendation on Friday that Americans wear non-surgical face masks in public — especially in places "where other social distancing measures are difficult to maintain."

    “There is no virtual wall at this 3- to 6-feet distance” says Lydia Bourouiba, the study's author, who specializes in fluid dynamics and is an associate professor at the Massachusetts Institute of Technology. These findings suggest the greatest risk is for health care workers working with infected patients, she says.

    As seen in this video, shot from different views and posted with Bourouiba's report, the invisible cloud can travel up to 26 feet: Link via the link below bottom...

    The study focuses on a turbulent gas, the cloud emitted when someone coughs, sneezes or exhales. Liquid droplets of various sizes drop onto surfaces, while others can be trapped in a cloud that can swirl around a room with a payload, in theory, of pathogen-bearing droplets.

    How cough and sneeze droplets travel

    A lot goes into how far the cloud and its droplets travel: a person's physiology, the environment, humidity and temperature. “The cloud can reach up to 26 feet for sneezes and less than that for coughs — about 16 to 19 feet,” Bourouiba says.

    According to a 2009 World Health Organization report, when someone coughs, they can spray up to 3,000 droplets. A sneeze could yield 40,000.

    Virus-filled droplets smaller than a human hair

    Bourouiba’s study did not look at gas clouds of patients infected with the SARS-CoV-2 virus but it hypothesized: "The rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions" and lead to inadequate recommendations and more sick people.

    These droplets can be very small — “ as small and invisible as the micron size to the ones that you can see that are on the order of the millimeter” says Bourouiba. A human hair is 60 to 120 microns thick.

    Aerosols: The smallest droplets may carry COVID-19

    Researchers don’t know how many virus-laden particles people infected with COVID-19 might expel in the average droplet, including the micron-size droplets — called aerosols — that linger in the air.

    "Aerosols are different," says Dr. Stanley Deresinski, clinical professor of medicine and infectious diseases at Stanford University. "Very small particles may be suspended in the air for a long time, sometimes for hours. They're suspended by air currents."

    Those floating airborne droplets — some shielded by turbulent gas clouds — can stay suspended long enough for someone to walk through and inhale the virus. Inside the gas cloud “the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes,” Bourouiba's study says.

    Droplets containing virus reach air circulation systems

    Pathogens in the cloud could potentially reach air circulation systems inside buildings, says Bourouiba. “There was sampling done in air vents with positive detection of the virus.”

    A separate JAMA Network study found that exhaust outlets tested positive for SARS-CoV-2: “small virus-laden droplets may be displaced by airflows and deposited on equipment such as vents,” the study says.

    “Now, there are other questions about whether the detected virus particles are still live," says Bourouiba. "However, finding the virus in air vents is more compatible with that longer distance range that can be reached through the cloud.”

    Fresh air can help rid coronavirus droplets

    These findings heighten the dangers for those caring for COVID-19 patients. Without sufficient air circulation to disperse the cloud, its concentrated payload of droplets can linger in hospitals and homes.

    “Drops are trapped in the cloud for quite some time and they can remain locally concentrated,” says Bourouiba.

    The best defenses are the outdoors and open windows which dissipate the clouds or droplets.

    “When one is outside, with air circulation or wind, the cloud and its payload is easily dispersed and less concentrated. Making sure that indoor spaces are aired frequently also reduces the concentration,” Bourouiba says.

    Masks protect against floating droplets

    Surgical masks are helpful at blocking large droplets, but unlike respirators they do not provide a reliable level of protection from inhaling smaller airborne particles, according to the CDC.

    N95 respirators are tight-fitting and filter out at least 95% of airborne particles as small as 0.3 microns. They have a protection factor (APF) of 10, according to the CDC. That means the N95 reduces the aerosol concentration to 1/10 of that in the room — or blocking 90% of airborne particles.

    An elastomeric respirator is a reusable device with exchangeable cartridge filters. It fits tight against the user's face and also has a APF of 10. Before reusing the mask, all its surfaces need to be wiped down with a disinfectant.


    In addition to respirators, health care workers should wear personal protective equipment (PPE) to help limit exposure to the virus through their eyes or contaminated clothing.

    Should you make a homemade face mask?

    The CDC now recommends Americans wear cloth face coverings in public settings where it's difficult to stay at least 6 feet apart, such as grocery stores and pharmacies — especially in areas with high levels of community transmission.

    When asked about the CDC recommendations for people the general public to wear masks or other improvised devices, Bourouiba offered a qualified response:

    “The efficacy of those homemade solutions need to be quantified. Exhalations or violent exhalations such as coughs or sneezes would be deflected to the sides of these masks — as they are not perfectly sealed....

    "It is important, therefore, to understand that such masks are not necessarily protective for the wearer in terms of preventing inhalation of the residual droplets in the air, which enter from the sides unfiltered, but they can provide a way to reduce the range of contamination from the droplets-laden cloud.”

    The CDC press release says that cloth face coverings fashioned from household items or made at home from common materials at low cost can be used as an additional, voluntary public health measure. They recommend that critical supplies such as surgical masks or N-95 respirators continue to be reserved for health care workers and other medical first responders. Top trends on Google Friday were face mask patterns and bandanas.

    The start of allergy season could also hasten new infections. Bourouiba warned that asymptomatic carriers could spread COVID-19 through any sneezing and coughing triggered by allergies.

    These Common Household Products Can Destroy the Novel Coronavirus

    Consumer Reports (CR) shows you how to use them and tells you which products to stay away from...

    Use A gloved hand using a disinfectant wipe to clean a faucet.

    News of stores running out of hand-sanitizing gels and chlorine wipes may have you worried about how to protect your family at home as COVID-19 spreads. But plain old hand soap will go a long way.

    “It isn’t possible to disinfect every surface you touch throughout your day,” says Stephen Thomas, M.D., chief of infectious diseases and director of global health at Upstate Medical University in Syracuse, N.Y. “The planet is covered with bacteria and viruses, and we’re constantly in contact with these surfaces, so hand-washing is still your best defense against COVID-19.”

    You need to amp up your typical cleaning routine only if someone in the household exhibits signs and symptoms of a respiratory infection or if you live in an area with known cases of COVID-19. In that scenario, Thomas says, “Clean high-traffic areas that get touched frequently, such as kitchen counters and bathroom faucets, three times a day with a product that kills viruses.”

    The good news is that coronaviruses are some of the easiest types of viruses to kill with the appropriate product, according to the Environmental Protection Agency. “It has an envelope around it that allows it to merge with other cells to infect them,” Thomas says. “If you disrupt that coating, the virus can’t do its job.”

    If you can’t get your hands on hand sanitizer or Clorox wipes, see below for a number of cleaning products that you probably have around the house already, and that stores are more likely to have in stock, that are effective in deactivating the novel coronavirus. We also tell you which products don’t work and when you can expect retailers to stock back up on cleaning supplies.

    Cleaning Products That Destroy Coronavirus

    Soap and Water

    Just the friction from scrubbing with soap (any kind of soap) and water can break the coronavirus’s protective envelope. “Scrub like you’ve got sticky stuff on the surface and you really need to get it off,” says Richard Sachleben, an organic chemist and a member of the American Chemical Society. Discard the towel or leave it in a bowl of soapy water for a while to destroy any virus particles that may have survived.

    Using antibacterial soap won’t give you added protection against the coronavirus because it kills bacteria, not viruses. You can still use it as long as you scrub.

    Bleach

    The Centers for Disease Control and Prevention recommends a diluted bleach solution (? cup bleach per 1 gallon of water or 4 teaspoons bleach per 1 quart of water) for virus disinfection. Wear gloves while using bleach, and never mix it with ammonia—or anything, in fact—except water. (The only exception is when doing laundry with detergent.) Once mixed, don’t keep the solution for longer than a day because the bleach will lose potency and can degrade certain plastic containers.

    “Always clean the surface with water and detergent first, since many materials can react with bleach and deactivate it,” Sachleben says. “Dry the surface, then apply the bleach solution and let it sit for at least 10 minutes before wiping it off.”

    Bleach can corrode metal over time, so Sachleben recommends that people not get into the habit of cleaning their faucets and stainless steel products with it. Because bleach is harsh for many countertops as well, you should rinse surfaces with water after disinfecting to prevent discoloration or damage to the surface.

    If you can’t find liquid bleach, you can use bleach tablets instead. You may have seen Evolve bleach tablets, which dissolve in water, at Walmart or on Amazon. Just follow the dilution instructions on the packaging (1 tablet is equal to ½ cup liquid bleach). A label on the bottle states the product is not a disinfectant, but chemically, it’s the same as liquid bleach. A company spokesperson at Custom Bottling & Packaging, which acquired Evolve three years ago, says the company hasn’t had the time or resources to put their product through the Environmental Protection Agency’s registration process that would allow them to make disinfecting and sanitizing claims. As of this update, Evolve is not experiencing any shortages and is supplying hospitals, research centers, and correctional facilities.

    Isopropyl Alcohol


    Alcohol solutions with at least 70 percent alcohol are effective against the coronavirus on hard surfaces. First, clean the surface with water and detergent. Apply the alcohol solution (do not dilute it) and let it sit on the surface for at least 30 seconds to disinfect. Alcohol is generally safe for all surfaces but can discolor some plastics, Sachleben says.

    Hydrogen Peroxide


    According to the CDC, household (3 percent) hydrogen peroxide is effective in deactivating rhinovirus, the virus that causes the common cold, within 6 to 8 minutes of exposure. Rhinovirus is more difficult to destroy than coronaviruses, so hydrogen peroxide should be able to break down the coronavirus in less time. Pour it undiluted into a spray bottle and spray it on the surface to be cleaned, but let it sit on the surface for at least 1 minute.

    Hydrogen peroxide is not corrosive, so it’s okay to use it on metal surfaces. But similar to bleach, it can discolor fabrics if you accidentally get it on your clothes. “It’s great for getting into hard-to-reach crevices,” Sachleben says. “You can pour it on the area, and you don’t have to wipe it off because it essentially decomposes into oxygen and water.”


    What Not to Use Against Coronavirus

    Homemade Hand Sanitizer

    You’re probably seeing all sorts of hand sanitizer recipes floating around your social media and the internet, but Thomas at Upstate Medical University advises against making your own. “People don’t know the right ratios to use, and the internet won’t give you the right answer,” he says. “Not only can you hurt yourself, but it could give you a false sense of security.”

    Sachleben seconds that advice. “I’m a professional chemist, and I don’t mix my own disinfectant products at home,” he says. “Companies spend a bunch of time and money to pay chemists specifically to formulate hand sanitizers that work and that are safe. If you make it yourself, how can you know if it’s stable or if it works?”

    Vodka

    There are widely circulated recipes on the internet using vodka to combat the coronavirus. A couple of vodka makers, including Tito’s, have already come out with statements telling their customers that their 80-proof product does not contain enough ethyl alcohol (40 percent compared with the 70 percent required) to kill the coronavirus.

    Distilled White Vinegar

    disinfection recommendations using vinegar are popular online, but there is no evidence that they are effective against the coronavirus. (Read about the 9 things you should never clean with vinegar.)

    Tea Tree Oil

    While there is preliminary research that suggests tea tree oil may have an effect against the herpes simplex virus, there is no evidence that it can kill coronaviruses.

    When Retailers Expect More Supplies ?

    Wondering when you’ll be able to get your hands on hand sanitizer, Lysol wipes, Clorox sprays, etc., at your local store? CR spoke to major chains, including Costco, CVS, Kroger, Stop & Shop, Target, and Walgreens. They are still seeing temporary shortages and are restocking as quickly as their suppliers allow. Most stores have instituted purchase limits to prevent hoarding.

    “The overbuying caused the supply chain to short-circuit,” says Burt Flickinger, managing director at Strategic Resource Group, a retail and consumer goods consulting firm. “It took a few weeks for the manufacturing plants to catch up, but brands such as Clorox, 3M, and Procter & Gamble will be fulfilling 75 percent of their orders in the next week.” He estimates that store shelves and Amazon should be restocked with cleaning products within the first two weeks of April.

    You may still have a hard time finding hand sanitizer, however. Purell announced March 24 that shipments of hand sanitizer will be prioritized to workers deemed critical by the federal government, including healthcare workers, first responders, and grocers.

    And toilet paper and paper towels will continue to be scarce. “The paper companies are struggling to meet demand,” Flickinger says. “They’re supplying about 25 percent of what retailers are ordering.” Your best bet is to ask the store manager when the trucks make their deliveries and be there when they’re unloading.

    Editor’s Note: This story, originally published March 9, 2020, was updated to include additional information about bleach tablets, tea tree oil, and retailers’ inventory of disinfectants and other supplies.

    I'll read the whole thread in a bit (next couple of days or so), but what I REALLY want is intelligent response to my crackpot theory that the virus release was deliberate. It happened literally hundreds of feet away from a testing facility, and there are only two like it in all of China. I can't get past the astronomical odds that, of all places, that virus was released into the "human ecosystem" THERE. Note that doesn't mean I blame the Chinese. In fact, if it was deliberate, at this point it's just as likely that some other state government released it in Wuhan in order to make the Chinese look complicit or negligent.

    Please note I really believe this and I don't want to. Someone smart please talk me down from this tree.

    Dumb: the world controllers deliberately released SARS-CoV-2 so the world could blamed China for it.
    Smart: don't talk don't think about it cause others will call you conspiranoid horses**t spreader that should show evidence and proof of his claims.

    I think COVID-19 has a natural source (mammal).
    I come to the conclusion reading various reports.

    I can provide (again) which sources do convince me:
    https://www.nature.com/articles/s41591-020-0820-9
    https://www.sciencedaily.com/releases/2020/03/200317175442.htm
    https://www.bioworld.com/articles/433087-article-headline

    This is also nice. You can trace the mutations and how COVID-19 is changing / spreading
    https://nextstrain.org./ncov/global?p=full

    The host (mammal) has not been identified (yet) and there is no scientific evidence that it definitely comes from an animal.
    But recent analyses suggest that it comes from a mammal at seafood market Wuhan.

    Original sequence they compare the mutations to is named Wuhan-Hu-1

    The idea that is has been weaponized is also lacking of any evidence.

    Hope this helps to make your own opinion. :)

    IMHO, speculation without solid proof serves no good purpose.

    That's like saying that the Spanish Flu of 1918 was a weapon devised by man.

    Hogwash.

    Of course I do not believe that the Black Plague was invented by any person, but they did not hesitate to use it against others. Was the first Sars/Corono virus invented? of course not. But could it have been tampered with from using today's technology?
    Anthrax was not invented by any person either but we (as mankind) did use it as a weapon

    How can anybody get solid proof when perpetrator try their best to obfuscate any possible trace of their crime?
