Meaning of "SOZO"?

I have read recently about the Greek word sozo, which means salvation, as I understand. But the writing indicated that sozo means salvation also in terms of making one whole and complete - spiritually, mentally, and physically - all three of them, all the time. Here are the three verses quoted...

Salvation “That if you confess with your mouth Jesus is Lord and believe in your heart that God raised Him from the dead you shall be saved (sozo).” Romans 10:9

Healing “But Jesus turning and seeing her said ‘Daughter take courage your faith has made you well (sozo) and at once the woman was made well (sozo).” Matthew 9:22

Deliverance “And those who had seen it reported to them how the man who was demon-possessed had been made well (sozo).” Luke 8:36

So the implication they make is that when a person is saved, it means they are not only healed "spiritually", but also that salvation means they are given freedom from the curse of sickness. Last time I checked, though, the death rate is still 100%. Can anyone shed some light on this? Is it maybe that "sozo" has different applications in different verses?

“Sozo” – Little Word, big meaning!

Strong’s exhaustive concordance says “Sozo” means: “to save, deliver or protect from; heal; preserve; do well; be made whole”.

Wow! What amazing things Jesus has given us by saving us!
