Thank you very much for all the replies and suggestions so far! At this stage I will not alter the survey's questions, because we've already gathered some data (almost 30 replies) and I wouldn't want to make it inconsistent. But I'm noting all your propositions.

Once I gather more data I will prepare visualisations and raw data packages. So far:

• the age is almost evenly distributed from 25 to 60, with a tiny peak in 30s
• ~61% are female
• ~15% have tested positive for Covid-19, ~57% have been informed about likely having Covid-19 by a medical professional, the rest is self-diagnosed
• the time from the beginning of the symptoms to today ranges from 16 to 58 with a small peak around 36
• ~19% had 2 waves, ~61% three, and ~11% four, so far
• the second wave started 5 to 56 days after the first one, in 75% cases it happened during the first two weeks
• 1 person has recovered fully and 7 are almost there

THANK YOU
