I would expect such a case to make the headlines, but it's quite possible it would be quietly swept under the carpet. How well known was Reston back when it happened? If that didn't make the news, would a lab-originated outbreak?
With COVID, a worker could get infected, hide the exposure out of fear/shame, never show any symptoms... and yet start a pandemic.
With a low-probability high-impact event like a global pandemic, near misses are the only indicator you have until the one time it does go catastrophically wrong.
From what I've read Ebola has killed many healthcare professionals because they infected themselves when disposing off PPE. As a result a disproportionally large portion of deaths were healthcare workers.

In many countries workers are actually incentivised to come to work sick and infect others.
It's not exceptional in many of the ways viruses can be. It's not as deadly as Ebola. Or as durable as Norovirus. Or as transmissible as Measles. It's just...really good at its job.
The lack of fomite transmission for SARS-CoV-2 has saved a lot of healthcare workers.
