The principal mode by which people are infected with SARS-CoV-2 is through exposure to respiratory fluids carrying infectious virus. Exposure occurs in three principal ways: (1) inhalation of very fine respiratory droplets and aerosol particles
The virus can also spread in poorly ventilated and/or crowded indoor settings, where people tend to spend longer periods of time. This is because aerosols remain suspended in the air or travel farther than 1 metre (long-range).

A guideline to limit indoor airborne transmission of COVID-19
空気感染は感染者が吐き出したエアロゾル飛沫を吸い込むことで発生し、現在ではCOVID-19の主な感染経路と考えられている。本研究では呼吸器系の飛沫が室内で一様に混合されると仮定して,空気感染を軽減する
