Possibly silly question re stairs and window

So I live on the ground floor of a triplex, and the external staircase goes past my front window.

The layout is typical – the window in question is close to my workspace in the front half of a double room: I sleep in the other half. The window is the closest thing I have to a bedroom window.

Nobody hangs out on the stairs, but there are four apartments upstairs that use it.

This is the question: in this crazy time, is there any sanitary risk in having that window open with people occasionally passing up and down the stairs, not far from where I’d be seated at the computer? It’s probably slightly over 2 meters but not by much. The sidewalk is also right at the foot of the staircase.
