If you want to be reckless with your health, then do so. Just don't encourage others to do the same.
a) already had, but wasn't 100% sure and still took care of mate sick with it, not going to hide away like some girl, even at 50% death rate I'd of been there.
b) the risk is so small, don't know your age and medical history but your likely 30's and healthy so 1 in 10,000 chance, but your life if you want to hide that's your call.
