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.

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.

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.

Coping with seasonal allergies

Are you one of 50 million Americans who suffer from allergies? Allergies are the fifth-leading chronic disease in the U.S. among all ages, and the third most common chronic disease among children under age 18, according to the Asthma and Allergy Foundation of America.

Allergy is characterized by an overreaction of the human immune system to a foreign protein substance (“allergen”) that is eaten, breathed into the lungs, injected or touched. This immune overreaction can result in symptoms such as coughing, sneezing, itchy eyes, runny nose and scratchy throat. In severe cases it can also result in rashes, hives, lower blood pressure, difficulty breathing, asthma attacks, and even death.

In a series of new videos, Emory University pediatric allergist and immunologist Karen DeMuth, MD, discusses seasonal allergies, allergy triggers, coping methods, treatments and common allergy myths.

In another video series, DeMuth explores the link between asthma and allergies and the impact of air pollution on people with asthma.

DeMuth is an assistant professor of pediatrics in the Emory School of Medicine.  She practices at the Emory-Children’s Center and Children’s Healthcare of Atlanta.

Hear Dr. DeMuth talk more about allergies and the link between asthma and allergies.
