Some (very likely) reputable facts, anyone ? Perhaps not as dramatic as rank bloviations.
Coronavirus and zoonoses. The recent coronavirus is just another instance in the long history of zoonoses - diseases that jump from animals to humans. The domestication of the horse led to the virus responsible for the common cold in humans, while the domestication of chickens gave humans chickenpox, shingles, and various strains of the bird flu. Pigs were the source of influenza, and measles, smallpox, and tuberculosis emerged from cattle. When a virus successfully jumps species from an animal to a human (“patient zero”), and that version of the virus in turn succeeds in making the jump to a second human, those two people become the first two human vectors of human-to-human virus transmission.
Three-quarters of infectious diseases are the result of zoonotic spillovers, and the novel coronavirus is no exception. The term “coronavirus” refers to a family of viruses shaped like a crown, and it accounts for about 10 percent of common colds in humans. (Rhinoviruses are the predominant cause of the common cold.) Novel coronaviruses have made the jump into the human population on three occasions in the 21st century, each time causing a deadly pandemic: SARS (severe acute respiratory syndrome) in late 2002, MERS (Middle East respiratory syndrome) in 2012, and COVID-19 (coronavirus disease 2019) at the start of this winter.

… in conversations with The Washington Post, experts rejected the idea that the virus could be man-made. “Based on the virus genome and properties there is no indication whatsoever that it was an engineered virus,” said Richard Ebright, a professor of chemical biology at Rutgers University. Tim Trevan, a biological safety expert based in Maryland, said most countries had largely abandoned their bioweapons research after years of work proved fruitless.

“COVID-19 coronavirus epidemic has a natural origin - An analysis of public genome sequence data from SARS-CoV-2 and related viruses found no evidence that the virus was made in a laboratory or otherwise engineered.”

(The Lancet, February 19, 2020): “Statement in support of the scientists, public health professionals, and medical professionals of China combatting COVID-19”:
The rapid, open, and transparent sharing of data on this outbreak is now being threatened by rumours and misinformation around its origins. We stand together to strongly condemn conspiracy theories suggesting that COVID-19 does not have a natural origin. Scientists from multiple countries have published and analysed genomes of the causative agent, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and they overwhelmingly conclude that this coronavirus originated in wildlife, as have so many other emerging pathogens. This is further supported by a letter from the presidents of the US National Academies of Science, Engineering, and Medicine and by the scientific communities they represent. Conspiracy theories do nothing but create fear, rumours, and prejudice that jeopardise our global collaboration in the fight against this virus.
