Well the 15 minute exposure rule is now changing. Here is the recent information from the CDC. So I guess if you get out of the line in less than 15 minutes and don’t see the individual you were standing in line with at other places multiple times within 24 hours and it adds up to 15 minutes total you should be good.
“The Centers for Disease Control and Prevention has redefined what it considers “close contact” with someone who has COVID-19. The term refers to the amount of time one has to spend in the presence of a person with COVID-19 in order to contract the disease from them. And unfortunately, the concept of “close contact” has become even more restrictive.
Previously, the CDC described “close contact” as being within six feet of a COVID-19-infected individual for 15 minutes. In other words, if you were standing close to someone who had COVID-19 for at least 15 minutes there was a good chance you could become infected too.
However, now the CDC says that 15-minute time frame doesn’t need to be consecutive. Rather, now you are considered to have had “close contact” with an infected individual if you’ve spent a cumulative 15 minutes over a 24-hour period standing within six feet of them. In other words, if you spent five minutes near an infected individual at 8 a.m., four minutes with the same individual at noon, and six minutes with that individual at 7:30 p.m., you’re now considered to have had “close contact” and could have very well been infected yourself.”
