I remember at the outbreak of the Swine Flu, one of my colleagues came back from a holiday in Mexico, he felt ill, and what did he do? He returned to work of course. It was only after a number of people told him to see the doctor that he went, and was immediately quarantined. It turned out that it wasn't Swine Flu and he returned to work the next day.
Problem is nowadays, with all of the people who use their sick leave dishonestly, the return-to-work interviews, and the Bradford Factor in place at so many workplaces, a Survivor's type plaque would spread far faster than it would have done in the twentieth century, when a lot more people were honest about illnesses, and managers were more likely to send people home!
