Yeah, I firmly believe that stress lowers the function of the immune system, whether it's a human or a pet snake. Expos are very stressful for snakes, & a great place
for sharing stuff: knowledge and money among people, and sadly, mites and germs among snakes. Shedding shouldn't have anything to do with it, but the uneven
temperatures also may have. It's very frustrating & challenging for you to start off with a new snake that's ill.Poor little snake...
