Accident

A man enters a cab one evening. He instructs the driver to take him home, about a 20 minute drive, when a few minutes later the cab is struck by a car running a red light. The man in the back seat of the cab is severely hurt and loosing massive amounts of blood through a severed artery. The cab driver is uninjured but slightly dazed. Without hesitation the driver gets out and begins to help the man in the backseat. He applies pressure to the wound with his bare hands but the pressure causes the blood to squirt in all directions. He then takes off his shirt and uses it to control the bleeding until the paramedics arrive and relieve him.

Upon admittance to the hospital the cab driver is checked out and told he is fine for release, however the man in the back seat is in the ICU. The doctor finds through the passenger’s medical file that he has been diagnosed with HIV. Should the doctor tell the driver this information?
