In this world at this moment, it is just very hard to know who handles your stuff. Amazon has a huge warehouse in Edison, NJ, which is a virus hot spot. Amazon employees complain about lack of protective gears. So you can imagine what kind of protection the packages have from those delivery people.
All those food delivery services are popular at those large metro or urban areas, which are at the forefront of this outbreak. I just like everyone be careful and learn from the situations in Italy and Spain.
