Legitimate medical advice:
Stay home if you are fucking sick.
Unionize and fight for paid sick leave if your counterargument is financially driven.
Buncha pre 19th century pre-Enlightenment folks putting Typhoid Mary's numbers to shame.
About a year back, I felt pretty rough - cough, flu-like symptoms - so I tested myself at home, yep, I was positive for Covid! Damn! So I went to the Covid website in the country where I live it told me to get an appointment for a 'proper' PCR test and to inform the healthcare system if it was positive. That would have involved me travelling on a bus (potentially full of people) to get to the nearest PCR test centre which I thought was a pretty dumb idea so I quarantined myself for 5 days and didn't bother with a PCR test!
