I read an article in the New York Times today talking about the precautions the WHO would proscribe in the case of a human outbreak of H5N1.

One of the things meanitoned was that in Japan it is considered poilte when sick to wear a mask to work. (If people who are sick wear masks, it significantly reduces the transmission of disease. Even better is if the sick person does not shake hands with others. )

I wondered: How would you react if a coworker came to work wearing a mask?

Would you consider it polite?
Would you think ill of the individual?
Would you wear a mask yourself when sick, knowing it would prevent others from catching the disease?
How would you feel if someone refused a handshake, not wearing a mask, because ‘I am sick’?

For my part, I thought I would react negatively. I know I did when a woman showed up to my bridge club wearing a surgical mask. I presumed she was either taking immuno-suppressant drugs, or was paranoid. I think this reaction was unjust. Especially considering the close quarters, and aged opponents, preventing the spread of infection seems very decent. I thought I should experiment, and the next time I am sick, wear a mask to work. Thoughts?
