Abstract
Systems for detecting aerosolized viral loads in an airspace include a first and, optionally, a second volume of a liquid. The first volume includes particles sampled from the airspace, and the second volume is free of virus particles. A first conductivity probe is immersed in the first liquid, and a second conductivity probe is immersed in the second liquid. An alternating voltage is applied to each of the first and second conductivity probes. The difference between the resulting alternating currents through the first and second conductivity probes is determined, and is used to estimate the viral load in the first volume, and in the airspace.
