Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Reddit as window into opioid withdrawal strategies

Drug abuse researchers are using the social media site Reddit as a window into the experiences of people living with opioid addiction. Abeed Sarker in Emory's Department of Biomedical Informatics has a paper in Clinical Toxicology focusing on the phenomenon of “precipitated withdrawal,” in collaboration with emergency medicine specialists from Penn, Rutgers and Mt Sinai. Precipitated withdrawal is a more intense form of withdrawal that can occur when someone who was using opioids starts medication-assisted treatment Read more

CROI: HIV cure report and ongoing research

The big news out of CROI (Conference on Retroviruses and Opportunistic Infections) was a report of a third person being cured of HIV infection, this time using umbilical cord blood for a hematopoetic stem cell transplant. Emory’s Carlos del Rio gave a nice overview of the achievement for NPR this morning. As del Rio explains, the field of HIV cure research took off over the last decade after Timothy Brown, known as “the Berlin patient,” Read more

All the boulders at the same time

Emory is preparing to launch a center devoted to antibiotic resistance. On Wednesday, Arjun Srinivasan, one of the CDC’s point people for antibiotic use and hospital acquired infections, kicked off the preparations with a talk on the multifaceted nature of this problem.

Without attempting to cover everything related to antibiotic resistance (that would take a book — or several), I will note in an upcoming post how Emory and partners such as Children’s Healthcare of Atlanta already have begun assembling many of the necessary tools.

Tackling antibiotic resistance has to take into account the habits of physicians, the expectations of patient, improved surveillance and antibiotic overuse in agriculture, as well as research on new antibiotics and detecting dangerous bacteria. In short, it’s both a science and policy issue — captured well by the documentary Resistance.

At the end of his talk, Srinivasan made a remark that brought this home for me, saying “We just have to push all the boulders up the hill at the same time” in response to a question about balancing effort on science vs policy. Allusions to Sisyphus!

Yet he provided some hope too, highlighting a recent CDC study that models how a coordinated response to antibiotic resistance in health care facilities could substantially cut infections. Read more
