Original story from The Ohio State University (OH, USA). Gathering dust from buildings may hold promise as a more efficient way to track viral outbreaks in indoor settings, according to a new study. After collecting nearly 30 vacuumed dust samples from places like schools, university residence halls and office buildings, researchers simultaneously identified the presence of 54 distinct viruses, including SARS-CoV-2, influenza, norovirus, Epstein-Barr virus and others. Indoor dust tends to accumulate biological material shed by occupants and also integrates signatures from the air, surfaces and human activity over time, which means using these particles to monitor viral pathogen trends could aid early detection efforts against future outbreaks. “It’s really important that we understand broadly how to track disease in our community,” explained Karen Dannemiller, senior author of the study and an associate professor of civil, environmental and geodetic engineering and environmental health sciences at The Ohio State University (OH, USA). “Similar to wastewater monitoring, which tracks disease clusters on a large-scale level, we’ve created an intermediate tool that has those same benefits for a smaller population.” Compared to traditional sampling methods, dust-based techniques are advantageous because the particles are easily collected during routine cleaning, it requires no specialized plumbing access and dust can remain stable at room temperature for extended periods. These simple but critical aspects can lead to quick, high-resolution insights into what is happening within a specific space and help researchers take appropriate measures to address it, added Dannemiller. “This is groundbreaking work,” she continued. “While people…
