The answer to the question about spreading by sneezing or coughing is quite convoluted. It’s like they were trying to “bury the lede”. The simple answer is: “Yes, you can catch it, if an infected person sneezes or coughs directly on you.” So, it’s not as contagious as ordinary flu — but, it’s possibly a lot more contagious than we were being led to believe, until quite recently.
