Previous studies have demonstrated that SARS-CoV-2 is stable on surfaces for extended periods under indoor conditions. In the present study, simulated sunlight rapidly inactivated SARS-CoV-2 suspended in either simulated saliva or culture media and dried on stainless steel coupons. Ninety percent of infectious virus was inactivated every 6.8 minutes in simulated saliva and every 14.3 minutes in culture media when exposed to simulated sunlight representative of the summer solstice at 40oN latitude at sea level on a clear day. Significant inactivation also occurred, albeit at a slower rate, under lower simulated sunlight levels. The present study provides the first evidence that sunlight may rapidly inactivate SARS-CoV-2 on surfaces, suggesting that persistence, and subsequently exposure risk, may vary significantly between indoor and outdoor environments. Additionally, these data indicate that natural sunlight may be effective as a disinfectant for contaminated non-porous materials.
Over and over we've been told "to stay home" but increasingly, it is being shown that this virus tends to spread faster and easier indoor than outdoor.
So 'stay at home' should be replaced with 'stay outdoors in the sunshine', of course with the caution to use sunscreen and keep your distance from others as viruses can still spread from coughs and sneezes.
Researchers led by Shanna Ratnesar-Shumate from the National Biodefense Analysis and Countermeasures Center, Operated by BNBI for the US Department of Homeland Security, have found that simulated sunlight could effectively kill severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is responsible for the worldwide COVID-19 pandemic. The study titled, “Simulated Sunlight Rapidly Inactivates SARS-CoV-2 on Surfaces,” was published in the latest issue of the Journal of Infectious Diseases.

Etwas über Rosa Elefanten und wie gefährlich diese sein könnten wenn man keine Maßnahmen ergreift:
Am Ende meiner Litanei komme ich etwas vom Thema ab und behandle die Kleinwalsertal Affaire. Doch irgendwie sind diese Sachen doch verbunden. Auch hier handelt es sich um Elefanten: die Auflage des Mindestabstands wurde kürzlich von Seiten der Regierung in Österreich als "Babyelefant" bezeichnet.
Was bedeutet das? Hier geht es zum Ernst der Sache:
Glaube an Verschwörungstheorien :
Von bösen Mächten wunderbar geborgen
Es handelt sich hier um ein Essay von Anselm Neft in ZEIT ONLINE:
Über das Coronavirus zirkulieren sogenannte Verschwörungstheorien. Manche Menschen glauben an sie. Und als Glauben lässt sich das Phänomen auch am ehesten analysieren.

We must urgently develop measures to tackle the new coronavirus

Around the world, I am seeing efforts to support ‘quick-fix’ programmes aimed at developing vaccines and therapeutics against COVID-19. Groups in the United States and China are already planning to test vaccines in healthy human volunteers. Make no mistake, it’s essential that we work as hard and fast as possible to develop drugs and vaccines that are widely available across the world. But it is important not to cut corners.
Vaccines for measles, mumps, rubella, polio, smallpox and influenza have a long history of safe use and were developed in line with requirements of regulatory agencies.
I have worked to develop vaccines and treatments for coronaviruses since 2003, when the severe acute respiratory syndrome (SARS) outbreak happened. In my view, standard protocols are essential for safeguarding health. Before allowing use of a COVID-19 vaccine in humans, regulators should evaluate safety with a range of virus strains and in more than one animal model. They should also demand strong preclinical evidence that the experimental vaccines prevent infection, even though that will probably mean waiting weeks or even months for the models to become available.

DNA vaccines are based on the transfer of genetic material, encoding an antigen, to the cells of the vaccine recipient. Despite high expectations of DNA vaccines as a result of promising preclinical data their clinical utility remains unproven. However, much data is gathered in preclinical and clinical studies about the safety of DNA vaccines. Here we review current knowledge about the safety of DNA vaccines. Safety concerns of DNA vaccines relate to genetic, immunologic, toxic, and environmental effects. In this review we provide an overview of findings related to the safety of DNA vaccines, obtained so far. We conclude that the potential risks of DNA vaccines are minimal. However, their safety issues may differ case-by-case, and they should be treated accordingly.
There were discussions on Facebook about the subject of vaccines, lock-downs and possible second and third waves of COVID-19. I just want to pick out one, followed by my answer.
What do you know about SARS? Where is it now, how many "waves" of it since 2003 - just for an example. Pandemics such as these run their course in due time. By the time they have a vaccine (if ever - i.e. there never was one found for SARS*) it will have run its course and the vaccine irrelevant to go on the trash heap - but if it mutates, then the vaccines will be useless anyway, the same as many of the flu vaccines were useless, and some, like the swine flu, were even dangerous. But Pharma will have made billions in profit.
The way it is going now (with exceptions of a few bad pockets that are cited as scare stories) the curves are flattening, so in order to keep up the pharma propaganda, there has to be the specter of new waves projected, and as some say, much worse than the original - because without fear (which by itself lowers your immune system) they cannot exert the type of desired control to turn people into obedient robots.
Lets just drink the Cool-Aid.
So any claim that we can never return to normal unless there is a vaccine and everyone is vaccinated, is
irresponsible scaremongering. The fact hat such comes from the chancellor of Austria is however alarming.
To speculate what is behind all this, I leave to others - and you, dear reader: what does your common sense tell you?
As of 2020, there is no cure or protective vaccine for SARS that has been shown to be both safe and effective in humans. According to research papers published in 2005 and 2006, the identification and development of novel vaccines and medicines to treat SARS was a priority for governments and public health agencies around the world. In early 2004, an early clinical trial on volunteers was planned. A major researcher´s 2016 request, however, demonstrated that no field-ready SARS vaccine had been completed because likely market-driven priorities had ended funding. ............

well, yeah, but it is a strain of SARS
so what about SARS?
By 2004, SARS cases had slowed just as mysteriously as they had started in Guandong province of southern China 2 years earlier, in December of 2002. Yet the legacy of unanswered questions the pathogen left behind should keep scientists, public health officials, epidemiologists, and ethicists occupied for a long time to come. Why, exactly, should we revive discussion if it is no longer a pressing threat? After all, the SARS death toll is relatively low with 812 deaths worldwide. What’s more, the looming H5N1 avian flu virus is currently front page news. Even so, the SARS epidemic should not be filed away without appreciation of the lessons it taught.
Although short-lived, SARS forced us to face the unpleasant reality of global pandemics and to address the ethico-legal dilemmas that result from hasty public health measures.
