Researchers have discovered that high-frequency ultrasound waves can effectively destroy viruses that attack the respiratory system, such as influenza and various strains of coronavirus, without harming host cells. This breakthrough, detailed in a new study, could pave the way for innovative antiviral treatments that utilize a physical method rather than relying on toxic chemicals or biological drugs.
The study, published in Scientific Reports, explored the use of standard medical ultrasound frequencies (3 to 20 MHz) to target viruses. Unlike lower-frequency ultrasound, which can cause cavitation and generate harmful free radicals, this method appears to work through mechanical resonance. The ultrasound waves cause the outer shell of the virus to vibrate and collapse, a phenomenon researchers have dubbed the "popcorn effect."
Experiments exposed influenza viruses and several coronavirus variants, including the original strain, gamma, and delta, to ultrasound waves using standard medical equipment. Microscopic analysis revealed that the viral envelopes were severely damaged and disintegrated, leading to a dramatic reduction in the viruses' ability to infect cells and a significant decrease in viral load. Crucially, this process did not appear to damage the host cells.
While the study demonstrated that different virus variants exhibited slightly varying responses, suggesting a need for specific frequency adjustments, the core mechanism targets the virus's physical structure. This approach may offer an advantage over treatments that target genetic material or proteins, which are prone to rapid mutation. The researchers noted that further in-vivo studies on animals are necessary to confirm the safety and efficacy of this method for treating viral infections within the body before human trials can be considered.
