Chickenpox is unrelated to chickens

Since I have had the deep misfortune to hear this far too many times in the last few days, allow me to make it absolutely clear that chickens do not cause chickenpox.

If you suffer from the latter disease, you have clearly not followed UEA protocol for deep space travel, and your vaccination status is woefully out of date. Report to sickbay immediately or leave the planet.

For those who are to go on the expedition this coming week, you are also required to report to sickbay independent of your views on chickenpox. A health check is mandatory for those spending time on surface.
