“ Why do you think that? All at the same time?”
Because the truck stops are going to be major vectors. Once one truck stop becomes hot, it will spawn hundreds of cases, those cases will then create many other truck stop hot spots.
Truckers use the bathroom and shower in truck stops. Each shower room has its own toilet. Maybe 150 truckers will shower between the 5 or so showers during the day at a busy truck stop. Maybe over 1000 will use the restroom there in a 24 hour period.
Well at least they don’t use that hallway full of pay phones anymore. They do also tend to have video games and of course food service. Pilot and other travel centers also have a lot of non-truckers and are busy busy places
If they require the shower facilities to be disinfected between uses, it will slow down their use but it will also prevent the spread of the disease.
I will say that Love’s truckstops clean the heck out of those showers between truckers, not so much the restrooms. My youngest came back from Iraq on R&R and made us stop at the one nearest the airport so he could take a shower. Said he hadn’t had one in 3 days and he wasn’t going any longer. Cleanest bathroom I have seen in a public place in forever.
