Public health officials are now saying that 264 people sought treatment at 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 hospitals 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 the larger number includes people who delayed seeking treatment. For example, some people had ringing in their ears from the blasts and thought it might go away, but it 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.

Boston Marathon suspect's condition improves

Federal officials say the Boston Marathon bombing suspect's medical condition has improved.



From outsiders to bombing suspects in Boston

 Two U.S. officials say slain Boston bombing suspect Tamerlan Tsarnaev was an ardent reader of jihadist websites and extremist propaganda in the run-up to last week's marathon attacks that killed three people. Authorities believe neither Tamerlan nor his younger brother Dzhokhar had links to terror groups. But law enforcement officials have concluded based on an early interrogation and other evidence that the two brothers were motivated by an anti-American, radical version of Islam. On Tuesday, two officials said that Tamerlan frequently looked at extremist propaganda, including Inspire magazine, an English-language online publication aimed at aspiring lone-wolf terrorists. Both officials spoke on condition of anonymity because they were not authorized to discuss the investigation publicly.
