Events of Martian Rails: Mars Fever!

Martian Rails (2009), the crayon board game manufactured by Mayfair Games about railroading on the Red Planet in which players build tracks and haul freight, has a long list of events to which players can respond in order to generate revenue for their rail companies. For example:

Mars Fever! -- An outbreak of Mars fever has transmitted fear throughout the land. To halt the spread of the plague, the government prohibits movement to or from the jungles and to Small or Medium Cities. No track laying crews may enter these areas.
