There's only one doctor left at a hospital in Gaza called Kamal Adwan, and lots of people are sick and need help.
Soldiers from Israel were at the hospital for a few days, and now they're gone, but they left the hospital in a mess.
The soldiers said they found bad guys at the hospital, but the people who work there say that's not true.
Now people in Gaza are really struggling because there isn't enough food or water, and many people are getting sick.
