SARS-CoV-2 starts replicating in the throat, not the lungs. For that reason, a simple throat swab is enough to test for the virus. There's probably no need for an intrusive, unpleasant nasal swab.
The virus mostly spreads from people coughing on each other. It's a lot less likely that you'll catch the coronavirus by touching the same touchpad or toilet handle as an infected person.
