Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

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

Students and faculty aid CDC for H1N1 response

Last spring, as H1N1 avian influenza spread across the globe, the Centers for Disease Control and Prevention put out a call asking students to assist. Within three days, 85 students from Emory’s Rollins School of Public Health (RSPH) had volunteered.

Nick Schaad was among the students authorized to help man the CDC’s Emergency Operations Center at the height of the novel H1N1 outbreak. Once the CDC began to identify influenza clusters, students began conducting phone surveys.

Schaad says he was involved in the St. Francis prep school survey in New York. Students and staff member who were sick with any flu-like symptoms were identified. The team called them and asked about the size of their household, what they might have done to protect themselves, and any recent travel. The goal was to learn as much possible about H1N1 in advance of the fall flu season.

Like the students they teach, RSPH faculty became engaged in the H1N1 epidemic. Last spring, Emory physician and microbiologist Keith Klugman, MD, PhD, was recruited to join the CDC’s Team B, which includes experts from outside the CDC to quickly review and inform the agency’s efforts. CDC created Team B in the early 2000s to cope with the growing complexity of public health emergencies.

Klugman says his role included the bacterial complications of influenza. Evidence from 1918, notes Klugman, clearly shows that the great majority of deaths were due to bacterial complications of the flu. In other words, the flu itself could occasionally cause death on itss own. But it caused death mostly by facilitating a synergistic lethality between itself and bacteria.

Although much has changed since 1918, the bacteria that caused so many deaths still exist but are susceptible to antibiotics.

Klugman notes the evolution of the flu. He says so far it’s generally been moderate. However, by mixing with the circulating flu in the Southern Hemisphere, it could mutate and become resistant to the first line of flu drugs. It could also become more severe. Says Klugman, “We must remain ever vigilant.”
