Curious about double-Doored entryways

[Teaching3bears]

I am reading that airflow in a room or building can impact on Coronavirus transmission. I was wondering about double doorway entrances into buildings where there is about 8 feet between the doorways. If someone with coronavirus coughed in those entryways would the germs be more likely to stay in there and get trapped? What if the air there was particularly hot and dry and the fan system was moving it around a lot?
