|Description:||This “aerial” view of Manhattan was taken while looking west from the 110th floor of the former World Trade Center Tower 2, also known as the South Tower, in New York City, New York. The copper dome of the Two World Financial Center Building could be seen on the left. The building to the right in the foreground was the Three World Financial Center, while just behind it, the Four World Financial Center building could be seen, and the Hudson River was visible in the background.|
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.
