|Description:||Two New York City bridges, the Brooklyn (foreground), and the Manhattan, can be seen in this view looking east from the 110th floor of the World Trade Center Tower 2, also known as the South Tower, in the borough of Manhattan. The spans connect Manhattan Island on the left with the borough of Brooklyn across the East River. Note the atmospheric smog preventing a clear view of these structures.|
When the World Trade Center towers collapsed as the result of terrorist attacks on September 11, 2001, the CDC responded by sending 30 officers of the Epidemic Intelligence Service (EIS) to conduct surveillance at 15 hospitals around the city. EIS personnel monitored symptoms of diseases and injuries looking for patterns that could indicate a bioterrorism event. The daily input was gathered and provided to New York public health officials for analysis. The information gave officials an accurate picture of the city’s health needs in the critical days after the attack, allowing the public health teams to focus on the rescue and recovery efforts.
