The polio virus does not like higher temperatures. At 4°C it survives best outside a host, but only at certain soil conditions, and even then only for a half to one year.
Yes and no. There is actually a high rate of symptom-free polio carriers, but also implies a non-neglectable amount of carriers with symptoms. Which does not fit into the “25 yeare polio free” scenario.
What makes me wonder: if Gaza is polio-free for 25 years, where does the virus come from?
Most viruses come from our soil. This could be wild or just contamination due to the conditions.

It’s possible for people to carry the virus without actually getting sick. See Typhoid Mary, for example.

Now that’s a disturbing thought.
Especially as there is a party in the game that has the capabilities and a motive.
