New corona virus viable for up to nine days on smooth surfaces - wear personal protective equipment! Wash your hands! A team of German scientists from Greifswald and Bochum has published a research article on the survivability of the new corona virus. This suggests that the new corona virus is viable and contagious for up to nine days on smooth surfaces. Here is the message from n-tv: "The novel corona virus can survive on surfaces outside the human body for up to nine days - and still be contagious, as a German research team finds out. However, the scientists are also finding a way to massively decimate the virus. Corona viruses can remain on surfaces for up to nine days at room temperature and remain infectious. On average, they survive between four and five days, writes a research team from Greifswald and Bochum in the "Journal of Hospital Infection". "Cold and high humidity increase their lifespan," said Günter Kampf from the Institute for Hygiene and Environmental Medicine at the University Medical Center Greifswald. Since there is no specific therapy against coronaviruses, the prevention of infections is important. Like all droplet infections, the virus spreads through the hands and surfaces that are touched frequently. "In the hospital this could be doorknobs, for example, but also bells, bedside tables, bed frames and other objects in the immediate vicinity of patients," Kampf said. Together with the virologist Eike Steinmann from the Ruhr University Bochum, Kampf had compiled findings from studies on coronaviruses and their inactivation for a planned specialist book. Due to the current situation, they published the scientific facts in advance. They believe that their findings about other coronaviruses are transferable to the new 2019-nCoV virus. "Different coronaviruses were tested and the results were all similar," said Steinmann. For disinfection, the researchers recommend agents based on ethanol, hydrogen peroxide or sodium hypochlorite. If these are used in the correct concentration, they drastically reduce the number of infectious corona viruses within one minute - from one million to only 100 disease-causing particles. If preparations based on other active substances were used, they should at least have a limited effect against viruses. "As a rule, this is enough to significantly reduce the risk of infection," said Kampf. Other researchers had previously recommended hand washing more often.

Worth to note that this is a meta-analysis, indicating the following (the authors have looked at previous studies and do not include the 2019-nCoV!!):
"The analysis of 22 studies reveals that human coronaviruses such as Severe Acute Respiratory Syndrome (SARS) coronavirus, Middle East Respiratory Syndrome (MERS) coronavirus or endemic human coronaviruses (HCoV) can persist on inanimate surfaces like metal, glass or plastic for up to 9 days, but can be efficiently inactivated by surface disinfection procedures with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute. Other biocidal agents such as 0.05-0.2% benzalkonium chloride or 0.02% chlorhexidine digluconate are less effective."
It is impossible to clean every surface we will touch.
My question is, if cleanliness is a factor that weakens our immunity? If a person like Amou Haji will be immunized against this novel coronavirus?

In connection with the appearance of this virus, I cite below the paper of 2007 titled "Generalized hypothesis of the origin of the living-matter simplest elements, transformation of the Arhean Atmosphere, and the formation of methane-hydrate deposites" (Victor E. Ostrovskii, Elena A. Kadyshevich, Physics - Uspekhi, 50 (2) 175-196; available at the RG site). We wrote in page 192 the following.
"It may be conjectured that subterranian or submarine natural biolaboratories still exist in our time in some coastal areas of southeast Eurasia, along great Chinese rivers or elsewhere. One can hardly guarantee that newly appearing varieties of viruses that from time to time manifest themselves in nature arise as a result of mutations alone."
And ibid, p. 180: "Living matter presently existing on the Earth originated on our planet rather than elsewhere in the universe. It developed from the simplest inorganic and organic mineral substances as a result of inevitable thermodynamically predetermined chemical processes and general physicochemical laws as opposed to random events and essentially nonequilibrium processes , such as electric discharges and the like..."

Are there data on any specificity in the elemental composition of this virus? May be, some inorganic or metal-organic substance is capable of its chemical destroying.
Appropriate disinfection is not a major problem.
The genome size of 2019-nCoV varies between 26 kb and 32 kb. 2019-nCoV belongs to the B lineage of the beta-coronaviruses and it is related to the SARS-CoV virus. The four structural genes encode the nucleocapsid protein, the spike protein, a small membrane protein and the membrane glycoprotein with an additional membrane glycoprotein (HE) occurring in the HCoV-OC43 and HKU1 beta-coronaviruses. The virus is 96% identical at the whole-genome level to a bat coronavirus.

Dear All,
According to the Life Origination Hydrate Theory (LOH-Theory), living issues, including DNAs as such, viruses, simplest organisms, etc., originated in the methane-hydrate matrix structure from CH4 and NO3 and PO4 ions and, possibly, originate by this way in our time. We wrote in 2006:
“It is hardly probable that there are good reasons to exclude the possibility that an underground natural bio-laboratory exists anywhere in the south-eastern costal Eurasia or in the Earth’s crust under the Great China Rivers.”
(V.E. Ostrovskii, E.A. Kadyshevich, Thermodynamics of formation of nitrogen bases and d-ribose from mineral substances in light of the problem of origination of simplest elements of living matter, Thermochimica Acta 441 (2006) 69–78;

Dear Aleš Kralj, Dear All,
Your information on the temperature and humidity dependence of the coronavirus is in the context of the description of the conditions of the simplest living matter origination according to the Life Origination Hydrate Theory (LOH-Theory). Indeed, according to the Theory, the symplest DNAs, in particular, of viruses originate at the temperatures around 280 K and within the CH4-hydrate when water molecules are immobilized in the composition of the CH4-hydrate structure. It is known that the processes of DNA replication and mitosis also proceed under conditions when the gas-hydrate structure of intracellular protoplasma exists.
At the ResearchGate site, in the context of discussion of the causes of appearance of microorganisms in human brains, I also passed an opinion that new simple DNAs and new primitive organisms can be formed in the inter-cellular (not intra-cellular) protoplasm. It cannot be excluded that such processes can proceed in freshly-cooled sea-products.

While constant physical distance to other persons is strongly recommended by infectiologists and political/administrative authorities one realizes in German TV live shows that many (not all) actors there do not adhere at all to this (mandatory!) recommedation. What a shame.

Dear All,
The pandemia will be eventually overcome. The infectionists and biologists will do their duty. It is undoubtedly.
But this is not the first virus pandemia for the last 70 years.
It is necessary not only to search the methods of infections controlling but also the ways of the infections appearance and their multiplication.
Every day, biologists discover new simple living issues and not only the pathogenic ones and not only viruses.
Where do all these come from?
By what way do living matter originate?
Does it proceed from minerals? But, by what way does this occur?
Is it possible to regulate this process?
And there is one more principal question.
Is it possible the origination of new DNAs and new viruses and organisms within the intercellular protoplasm of living or recently died organisms and, if it is possible, how could this process be controlled?
I think that the scientific works in these directions should be intensified.
They are needed not only for the counteraction against virus infections but also for understanding of a number of the medico-biological problems such as parasitology, natural lifetime limitation, optimal nutrition, origination and artificial realization of the chirality phenomenon and racemization delay, production of drugs, discovering of the molecular mechanism of mitosis and DNA replication, decision of a number of the paleontological problems etc.

I think control of flies will become important, too.
I came across this piece of research regarding the transmission of a coronavirus strain via common houseflies. The reference is as follows:
Calibeo-Hayes D, Denning SS, Stringham SM, Guy JS, Smith LG, Watson DW. Mechanical transmission of turkey coronavirus by domestic houseflies (Musca domestica Linnaeaus). Avian diseases. 2003 Jan;47(1):149-53.
There is an emerging realisation COVID-19 is not only transmitted by aerosol but also by the fecal-oral route. Bearing this in mind would it be appropriate to advise the general public at large to keep flies out of their homes during the current crisis? Secondly, in countries where open defecation is practiced should there be a concerted drive to control insects?
