If you took an antigen test at your local pharmacy or a PCR test at cantonal hospital, you had to fill out a form where you write your phone. If the result is positive, you get an SMS with isolation instructions and a web link to enter your data for statistical purposes and indicate the people you had contact with and most importantly if you were in contact with coworkers.
Some days later after you filled out the online form indicating your email, you get 2 PDF docs: 1) one stating your isolation period and 2) a justification you send to work for the days you stayed in isolation.
Thanks very much for all the info and cheer. By the way Sigh, can I ask where you know that info from, about not contacting authorities? I'm just being extra cautious coz I dont want to upset the authorities.
If you wish to travel in the near fitire, you may wish to get a recovered certificate as your PCR could be positive for quite a while, which would make entry to many countries impossible.
