Scientists Use Sound Waves to Destroy COVID and Flu Viruses in Lab Tests
Researchers from the University of São Paulo in Brazil have demonstrated that sound waves can effectively destroy influenza A (H1N1) and SARS-CoV-2 viruses in laboratory settings. The study utilized ultrasound machines, commonly found in hospitals, to expose the viruses to frequencies ranging from 3 to 20 MHz. The sound waves caused the viral particles' membranes to rupture, rendering them inactive. This method, which relies on acoustic resonance, targets the physical structure of the virus rather than a molecular pathway, potentially offering a new approach to combat viruses as they mutate. The research is still in its early stages, with further studies needed to refine the ultrasound frequencies and test the method on other viruses like dengue and Zika.
