Duality Between Coronavirus Transmission and Air-Based Macroscopic Molecular Communication

Area of Science:

• Biophysics
• Communication Engineering
• Epidemiology

Background:

• Viral infections spread via airborne aerosols and droplets.
• Macroscopic molecular communication principles can model biological transmission.
• The coronavirus pandemic highlighted the need to understand airborne transmission.

Purpose of the Study:

• To model viral infection spread as a molecular communication scenario.
• To experimentally investigate airborne particle transmission during respiratory events.
• To evaluate the efficacy of masks in reducing particle emission.

Main Methods:

• Developed a macroscopic air-based molecular communication testbed.
• Used artificially induced coughs with fluorescent dye-traced saliva.
• Employed optical detection for particle visualization and quantification.
• Extended a simulation tool for molecular communication processes.

Main Results:

• Significantly fewer particles were detected when wearing masks compared to no protection.
• Experimental data informed simulations of infectious aerosol transmission.
• The study quantified particle reduction attributable to mask usage.

Conclusions:

• Masks are effective in reducing the emission of infectious aerosols.
• Molecular communication provides a framework for understanding airborne disease spread.
• This research offers insights into mitigating transmission in various environments.
