The world’s second largest Ebola outbreak on record was declared over on 25 June 2020. ... (2020). "We don't have any other data to support it, including cell culture data. This has been shown by scientists led by Tanja Stadler, a professor at ETH Zurich's Department of Biosystems Science and Engineering in Basel; they published the corresponding study in the journal When Ebola developed into an epidemic in 2014, an international team of scientists estimated that the pathogen's genome would change on average every 9.5 days, based on virus samples and computer simulations.
Generally the drift should be in the direction of making it less virulent, less dangerous, not more, if it's selected for, because it wants to keep its host alive."

Dr. Scott Gottlieb says coronavirus mutation study 'doesn't prove' new strain more contagious. There are nearly 3.7 million confirmed cases of Covid-19 across the world, according to Got a confidential news tip? Although the arguably-corrupt World Health Organization (who) has declined to declare Covid-19 a global pandemic, it already is one according to two of three CDC criteria: It has sustained person-to-person spread, and it kills people.
They showed that when viewed over the whole epidemic, the pathogen only changed at its typical slow speed.ETH researchers have now shown that the high estimated mutation rates at the start of the epidemic were due to the limited number of virus samples at the time in combination with the computer models used, which calculate the estimates using genetic data from virus samples and from underlying assumptions.
Have any problems using the site? Gottlieb said there are different strains of the coronavirus circulating, but contended that mutation alone does not mean it is more contagious.

She highlights that the early estimates for the Ebola epidemic based on a small dataset were heavily influenced by assumptions, which in retrospect have proven to be inaccurate.Current computer models, however, do not simplify reality as much as those used a few years ago, and they are less heavily influenced by the underlying assumptions, says Stadler. The nearly two year long outbreak was particularly challenging because it took place an active conflict zone. "It doesn't prove that this new strain is in fact more infectious," Gottlieb said on CNBC's "The analysis could be confounded by the fact that this just became the dominant strain in Europe because it got into Europe early and then got into the United States from Europe," contended Gottlieb, a former head of the U.S. Food and Drug Administration. While the new models -- some of which are being developed in the Stadler group -- are more complex and require a lot more computation, they provide more accurate results even at the start of an epidemic, when very little genetic data is available.
