Are gunshot wound infections always fatal?

GSW: Gunshot wounds that are complicated by an infection are not uniformly fatal but certainly can at times lead to mortalities. Mortality rates and infection rates typically depend on the location of the injury. Antibiotics have been quite effective in reducing infection related complications this however will not always be the case

Not any more: In the civil war, leg wound infections from gunshot wounds were so lethal that the best treatment was to cut the leg off. Today unless the bullet destroys a vital organ or blood vessel death from infection usually isn't a problem due to a variety of antibiotics and modern surgical techniques, but i still don't recommend getting shot!

Depends: If the infection is near to the skin level and there is little or no tissue damage, could be easily treated. If the infection is deep within the body or involves injury to blood vessels or the GI tract, it is much more serious., but, no, gunshot wound infections are not always fatal.

No: Many bullets are left in place if removal would cause more damage. The body does a good job of fighting infections. New antibiotics help. It is rare to die from an infected GSW. Though other complication can arise.
