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
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
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
One of the most important lessons from this past yearâ€™s pandemic, Fauci said, is the need to â€œconnect the dotsâ€ between seasonal and pandemic influenza and not view them as two separate phenomena.
â€œRather than trying to figure out one priority group over another,” Fauci said, “if we can get into a rhythm of getting most people vaccinated each year, we will have most of the population with some degree of immunity. We will get into a situation where we donâ€™t need to go from a seasonal approach to a crisis approach.
The scientists in the lab of Richard Compans, PhD, professor of microbiology and immunology at Emory, are hard at work, imagining the unimaginable: A time when patients can self-administer flu vaccines. A time when vaccination does not require exposure to inactive viruses. A time when a universal vaccine could protect from all varieties of influenza: swine, avian, seasonal and strains still emerging.

But it’s not just hope that motivates them as they work. Emory’s scientists are fighting the clock against another possible future: a time of pandemic and uncontrollable virus mutation. The recent emergence of H1N1 and H5N1, known colloquially as swine flu and avian flu, have added an even greater sense of urgency to their task.
“The H5N1â€”the virus derived from avian speciesâ€”has a 60 percent mortality,” says Emory microbiologist Sang-Moo Kang, PhD. Yet that strain of influenza hasn’t resulted in many human deaths, because, so far, avian flu spreads only to humans who are in contact with infected birds.
While in Atlanta, Chan also visited Emory to meet with President James Wagner and Emory Global Health Institute Director Koplan. She heard presentations about global health field projects by students in public health, medicine, and theology.
Chan recalled the â€œlost decade for development,â€ the 1980s, a dismal time for public health. The 1979 energy crisis followed by a recession made for tighter public health resources and few health care improvements worldwide, she explained. Some developing countries have still not recovered.
In contrast, public health has faired better in the new millennium, when the world has benefited from financial commitments backed by substantial resources, often from innovative sources, says Chan. Read more
