“The researchers identified more than 2,300 passengers known as “index patients” who developed COVID-19 within 14 days of their train trip, and more than 72,000 passengers who sat near these cases — within three rows (widthwise) and five columns (lengthwise) of the index patients.Overall, 234 of the 72,000 nearby passengers developed a COVID-19 infection linked to their train ride. That means the average “attack rate” — or percent who tested positive out of the overall group — was about 0.32%. Those who sat directly next to an infected person had the highest risk of contracting the infection, with an average attack rate of 3.5%.”

Keeping concentrations low of any pathogen is important.
