There was a post in one of the camino groups on Facebook where an albergue/gîte owner describes how one of the pilgrims/walkers staying at his place knocked on his door in the middle of the night and told him that he was not feeling well: headache, shuddering, tummy ache and so on, and what happened during the next hours and days. I won't go into more details.
It struck me how deeply divided forum/online opinions are: the constant and repetitive "stay at home, don't travel, you are irresponsible" appeals; the belief that it will be alright if one follows the recommendations of hand hygiene, distancing, face masks etc and raving reports about how glorious it is to walk right now in Spain and Portugal.
Nobdy seems willing to address what one can do to prepare for all eventualities: downloading and using the recommended warning app; keeping a contact diary; thinking about what to do if one has first mild symptoms that could be Covid-19 or numerous other ailments and being ready and determined to do it; thinking about what to do while waiting for Covid-19 test results which can apparently take anything between hours and days (in France or Spain) and being prepared to do it.
