The Health 202: Genetic tracing could show how coronavirus spread through White House (Washington Post)

Washington Post: The Health 202: Genetic tracing could show how coronavirus spread through White House. “The Trump administration could, if it chose, search samples taken from dozens of White House staff members and visitors for tiny genetic variants. Because the virus undergoes slight changes as it moves from person to person, it’s possible to map where it has moved by looking for similarities in mutations. White House spokesman Judd Deere said tracing has been done for people who had contact with Trump. But it’s the kind recommended by the Centers for Disease Control and Prevention, which involves merely tracking people who were nearby those known to be infected.”

The Washington Post: Massive genetic study shows coronavirus mutating and potentially evolving amid rapid U.S. spread

The Washington Post: Massive genetic study shows coronavirus mutating and potentially evolving amid rapid U.S. spread. “Coronaviruses such as SARS-CoV-2 are relatively stable as viruses go, because they have a proofreading mechanism as they replicate. But every mutation is a roll of the dice, and with transmission so widespread in the United States — which continues to see tens of thousands of new, confirmed infections daily — the virus has had abundant opportunities to change, potentially with troublesome consequences, said study author James Musser of Houston Methodist Hospital.”

Coronavirus mutations: what we’ve learned so far (The Conversation)

The Conversation: Coronavirus mutations: what we’ve learned so far. “In early January, the first genome sequence of Sars-CoV-2 – the virus that causes COVID-19 – was released under the moniker ‘Wuhan-1’. This string of 30,000 letters (the A, T, C and Gs of the genetic code) marked day one in the race to understand the genetics of this newly discovered coronavirus. Now, a further 100,000 coronavirus genomes sampled from COVID-19 patients in over 100 countries have joined Wuhan-1. Geneticists around the world are mining the data for answers. Where did Sars-CoV-2 come from? When did it start infecting humans? How is the virus mutating – and does it matter?”

Phys .org: Machine-learning model finds SARS-COV-2 growing more infectious

Phys .org: Machine-learning model finds SARS-COV-2 growing more infectious. “The model, developed by lead researcher Guowei Wei, professor in the departments of Mathematics and Biochemistry and Molecular Biology, analyzed SARS-CoV-2 genotyping from more than 20,000 viral genome samples. The researchers analyzed mutations to the spike protein—a protein primarily responsible for facilitating infection—and found that five of the six known virus subtypes are now more infectious.”

CNET: The coronavirus is mutating, but you shouldn’t freak out about it

CNET: The coronavirus is mutating, but you shouldn’t freak out about it. “Viruses mutate. That’s a thing they do, and it happens all the time. In some cases, viral mutations can be bad: They can cause an already-malignant virus to become worse, more contagious or more deadly. In many cases, however, viral mutations are rather benign. They don’t change much about the virus or the way it spreads. The novel coronavirus — aka SARS-CoV-2 (the actual name of the virus) and COVID-19 (the name of the disease) — has started to mutate, and people everywhere (OK, on Twitter) are freaking out.”

Washington Post: This coronavirus mutation has taken over the world. Scientists are trying to understand why.

Washington Post: This coronavirus mutation has taken over the world. Scientists are trying to understand why.. “When the first coronavirus cases in Chicago appeared in January, they bore the same genetic signatures as a germ that emerged in China weeks before. But as Egon Ozer, an infectious-disease specialist at the Northwestern University Feinberg School of Medicine, examined the genetic structure of virus samples from local patients, he noticed something different.”

Surveilling the virus: unprecedented amounts of genetic data and smart software are tracking how COVID-19 metamorphoses around the world (ZDNet)

ZDNet: Surveilling the virus: unprecedented amounts of genetic data and smart software are tracking how COVID-19 metamorphoses around the world. “The world has been obsessed with surveillance of a particular kind for six months: watching people to see who’s sick. There is another form of surveillance that is just as important but less well understood, and that is the attempt to track how the SARS-CoV-2 virus itself is metamorphosing as it spreads around the world.”
