Just travelling and stopping to a local gas station or other on the way can expose you to the virus if the area has it. Omicron is air transmitted, and the data for cloth masks continues to show that wearing one is mostly theatrical but of course with freedom you get to choose. I do think that if you have symptoms you should stay home as all fully vaccinated people can and are carriers so unless you are complete hermit, unfortunately, it will get you sooner or later 
BTW I got the first strain of Omi- 2 months ago and recovered in 2 days, if there was ever a time to get a strain of the virus it is now, as it is the weakest strain ever but I do not know your risk factors. IN any case Antivirals are available where you guys are and are able to reduce your viral load in the first days of being positive.
