New York City formed their own investigation bureau after 911. It would appear NYC also needs their own international bureau on diseases. It took a horrible toll on that city because airlines from Europe were not shut down.
The health investigators need to answer to the Health Department. The Health Department of any city has the authority needed to declare a health emergency, but, the idea of intelligence is to prevent the health emergency. Health officials will understand a report without any interpretation. Or. At least they should.
