Viral Load of SARS-CoV-2 in Respiratory Aerosols Emitted by COVID-19 Patients while Breathing, Talking, and Singing
Duke-NUS Medical School One Health Senior Research Fellow, Dr. Kristen Coleman, and fellow researchers in Singapore measured viral aerosol emissions from COVID-19 patients as they engaged in common activities. Participants were asked to breathe, talk, and sing into a special aerosol collection device (Gesundheit II machine) which captures both coarse and fine viral particles. Talking and singing produced the most detectable viral RNA, and fine particles (≤ 5 μm in diameter) made up 85% of exhaled SARS-CoV-2 particles. Participants earlier in their course of illness were significantly more likely to release detectable viral RNA via respiratory aerosols, consistent with previous studies showing correlations between viral load and day of illness.

Dr. Lexi Sack accepting postdoc position at University of Notre Dame
Duke NIH D43 postdoctoral fellow Lexi Sack (who graduated with a PhD in Translational and Clinical Science from Tufts University in August), has recently accepted a postdoc position in Dr. Jason Rohr's lab at Notre Dame. This work will focus on controlling schistosomiasis in disadvantaged communities with a secondary focus on improving livestock production, as a portion of the human infections in the study region in Senegal are a hybrid with the cattle variety. Congratulations, Lexi!
