Oh no, get better soon! I try very hard not to get sick because my numbers are bad enough without any illness - I always get the flu shot, stay away from people who look sick in public, and hide out in my room if someone at home is sick.
I'm sure your numbers will improve once you've recovered. Being sick makes your numbers high, and right now you're probably stressed about it which is not good for blood sugars either. Once you're better, I'm sure your numbers will come back to normal and you won't have to make any changes to your treatment. To prevent this happening in the future, perhaps you should discuss sick day management with your doctor so you have some strategies to put in place before ending up in hospital.
