“The reason is that it is incredibly airborne.”
Is that your explanation or do you have a source?
The incredible rate of infection tells you this. It's almost 3 times that of the flu. Also, if you can find the details, when the CDC investigated the first 4 cases in Montgomery County, TX, they discovered they were a group of people that walked through the Houston Livestock Show. All they did was walk into the building, walk through the arena looking at the animals, and walk out of the building. They ate nothing, they touched nothing. But, by the time the CDC figured this out, they had already infected many other people. Something else to look at is the huge bloom of cases in the New Orleans area, and Louisiana in general. What happens in Louisiana this time of year? Mardi Gras parades. Right now, Louisiana has over 700 more cases than Texas. It's big time airborne. No doubt about it.
