Here are the numbers: a sneeze leaves your nose at up to 320 kilometres per hour; up to 40,000 virally-loaded droplets are expelled and travel for up to eight metres; many of those droplets can stay suspended for up to 10 minutes.
A cough isn’t as powerful – 50kph and 3,000 droplets — but still impressive. Those droplets can contain 200 million individual virus particles.
In an open-plan office, two or three sneezes and you — a one-person hit squad — have potentially infected everybody in the room. Plus, you’ve jetted several loads of micro-mucous into the ceiling ventilation system. So, you’re well on the way to bringing down the entire floor.

And that's to protect non-immune compromised people!!
PS The article does contain a list of steps on how to contain infection for those unwell and still going to work. Might be handy to print out and hand to your coughing and sneezing work colleagues.
