In brief: Low Blood Pressure

Usually the body redirects blood to an affected area of illness which will lower the effective blood pressure and result in a person appearing pale.
Often when you are "sick" you become a little dehydrated which can do the same thing. This goes away when the illness is better. Fever will make you look flushed because blood is directed to the skin to remove the extra heat.
