China’s health authorities have admitted that people may contract the pneumonia-causing COVID-19 coronavirus by inhaling small virus-containing particles floating in the air, or so-called aerosol infection. Updated diagnostic and treatment guidelines published Wednesday say a person can be infected if they are exposed to a high concentration of aerosol in a relatively closed environment for a long time. This is the sixth edition of the guidelines for treating patients of the new virus in China. The guidelines posit that the main routes of transmission are “droplets from the respiratory system” and “close contact.”
Not to worry. This will all probably (so to speak) blow over.
