Once eaten, the host will still remain some intelligence, but lose all functions to speak, forget people who weren't very emotionally important in their life, and develop a wild craving for blood and bones.

The other infected will lose all intelligence, lose all functions to speak, forget everyone, and develop a wild craving for blood and bones.

In a rare occurrence, if someone was emotionally important to more than one person, they have a small chance to be 'reincarnated', however, in reality, they simply are the infected, but with some differences.

The 'reincarnated' will have a craving for murder instead of blood and bones and will purposely hide their disease to everyone around them, intentionally tricking the people they were emotionally important to.

Sometimes, if someone is really unlucky, the infected will be able to come back to life even if their body is almost entirely destroyed.

If someone is insanely unlucky, the infected will be able to come back to life even if their body is almost entirely destroyed while also being 'reincarnated', meaning two different versions of the infected person will exist.

If the two versions see each other, they will merge into one, regressing them back to a basic 'infected' state.
