There's really no evidence that a few days here and there of extremely low calorie eating triggers a permanent slowing of metabolism (what some folks call starvation mode). Rather, it's frequent and extended periods of fasting and very low calorie diets that are associated with reduced metabolism and other metabolic changes (for example as some research suggests, insulin resistance).
When you're ill, in general I think it's best to listen to your body. If you're hungry (even a little hungrier than normal) go ahead and eat, just try to make fairly healthy choices, sometimes when we're sick, we crave foods that we associate with comfort. Nothing wrong with that, as long as being sick isn't an excuse to eat everything we wouldn't otherwise; and if you're not hungry, don't eat.
Hope you feel better soon,
