Pick a window seat on trains

STUDIES show that people who travel by public transport are far more likely to get infected by viruses such as flu and Covid-19.

The degree of risk depends on how crowded the carriage is, and whether you wear a mask — but where you sit may also count.

In a study published last month in the journal Physics of Fluids, researchers used computer simulations to model airflow in closed carriages. They found that people standing in the aisle, or sitting in the aisle seat, were exposed to most virus particles — those by the window seat were subjected to the least. They also, of course, get the best view.
