High-Sensitivity Camera Shows How Viruses Are Spread From Person to Person via Microdroplets
New footage released this week shows how the likes of COVID-19 may be spread through minuscule droplets that are invisible to the naked eye. Using laser beams and high-sensitivity cameras, scientists in Japan were able to capture the droplets — measuring around 1/10,000 of a millimeter — that help viruses jump from human to human.
