"However, based on what we know about the incubation period for this virus, there’s almost no chance that your sister could have passed on the virus to your family members just 24 hours after being exposed herself."
"But you would still expect there to be a few days between the time a person is exposed and infected and the time they begin actively shedding virus. If we figure that infected people who become sick typically start experiencing symptoms a bit more than five days after exposure, we can calculate that infectiousness would, on average, begin rising sharply about three days post exposure. In other words, it’s safe to say that it would be exceedingly rare for anyone to transmit the virus earlier than two days post exposure."

==============
Put simply, if you are merely exposed to covid, you are not instantly contagious. In fact, there's no guarantee you'll be infected, at all. It depends on how much virus you are exposed to, and for how long. Viruses have an "incubation" period, so if you are exposed to only a tiny amount of virus, your body can most likely fight it off.
EXPOSURE + TIME is the critical factor. You are extremely unlikely to get infected from an infected person merely passing by.
READ THIS ARTICLE, it is very informative.
