Acute hand infections can be superficial or deep, with superficial infections occurring in the skin and deeper infections affecting tendons, joints, and bones.
Superficial infections like paronychia and felons are usually treated with warm soaks, splinting, and antibiotics, while deep infections like pyogenic flexor tenosynovitis require more aggressive treatment including surgery.
Conditions from herpes simplex virus, like herpetic whitlow, typically resolve on their own, but deep infections necessitate quick medical attention to avoid complications.
