Public health officials are now saying that 264 people sought treatment at Boston area hospitals for injuries sustained in the Boston Marathon bombings.

Authorities had been saying that about 180 people were injured, but that was just victims brought to the hospital in the immediate aftermath of the April 15 explosions. Three people were killed and at least 14 people lost all or part of a limb.

The Boston Public Health Commission says some people delayed seeking treatment, for example, people who had ringing in their ears from the blasts they thought might go away, but persisted for several days.

Other people sought delayed treatment for minor shrapnel wounds. Twenty-seven different hospitals treated the injured.

The commission said as of Tuesday, 51 people were still hospitalized.
