|Description:||Though on this day in 1988, there was considerable atmospheric smog obstructing a clear view, this photograph captured the pre-September 11, 2001 Manhattan skyline, with the former two World Trade Towers standing tall above the rest of New York City’s buildings. This image was taken from a Liberty Island vantage point.|
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.
