Scientists May Know Where Coronavirus Originated, Study Says
Months into the coronavirus pandemic, researchers are still investigating the actual event where the crossover of the novel coronavirus from animals to humans occurred. A team of scientists may have discovered the answer to the question many have been asking for months, according to a study published in Nature Microbiology. The group of scientists from the United States, China, and Europe compared mutation patterns of SARS-CoV-2, the virus that causes COVID-19, to other viruses, and created an evolutionary history of the related viruses. They discovered the lineage responsible for producing the virus that created the COVID-19 pandemic has been present in bats, according to the study. (McGorry, 9/17)

How Did Coronavirus Get Transferred From Animals To Humans? Scientists May Have An Answer
Nine months into the global pandemic, scientists are still piecing together the mystery of the first crossover event, in which the coronavirus moved from bats to an intermediary animal, and eventually, to humans. By comparing the patterns of mutations from the new coronavirus to other known viruses, researchers have been able to create an evolutionary history of the related viruses, and found a "single lineage responsible for the COVID-19 pandemic."

What The U.S. Did Wrong On Covid-19 — And What Others Did Right
Some governments have been praised for being forthright about being science-driven in the way they’ve communicated about the Covid-19 pandemic. Other countries, most notably the U.S. and the U.K., have been hit with criticism for public health messages that are confusing or not based in science. (Robbins, Garde and Feuerstein, 9/18)

US Reinfection Case Raises Question: How Long Does Covid Immunity Last?
Virologists largely expected reinfection could occur. But experts said the US reinfection case highlights the enduring mysteries of the coronavirus, including how long a person’s immune system protects against the virus after an infection and the virus’s interaction with individual biology. Reinfection cases are important also for the development of vaccines and assessing their impacts as the world’s medical community races to develop them. (Glenza, 9/17)
