They really shouldn't be in water in the first place the water takes off their natural oils. And cold water makes it worse it can cause respiratory problems cause it's to cold and their homeostasis or getting use to a temperature isn't as fast as ours. That's why in the winter if your hamster gets to cold it goes in to hibernation.
Swim in cold water.
If you are cold your body has a harder time trying to fight off infection. so if you swim in warm water then no, it will not get worse. however if you swim in cold water you may stay sick for longer. it would be rare for a cold to get worse though, just a longer duration.
