Concerns about what is now known to be the novel coronavirus pandemic were detailed in a November intelligence report by the military's National Center for Medical Intelligence (NCMI), according to two officials familiar with the document's contents. The report ... raised alarms because an out-of-control disease would pose a serious threat to U.S. forces in Asia - forces that depend on the NCMI's work. And it paints a picture of an American government that could have ramped up mitigation and containment efforts far earlier. Analysts concluded it could be a cataclysmic event," one of the sources said of the NCMI's report. "It was then briefed multiple times to" the Defense Intelligence Agency, the Pentagon's Joint Staff and the White House. From that warning in November, the sources described repeated briefings through December for policy-makers and decision-makers across the federal government as well as the National Security Council at the White House. All of that culminated with a detailed explanation of the problem that appeared in the President's Daily Brief of intelligence matters in early January. The NCMI report was made available widely to people authorized to access intelligence community alerts. Other intelligence community bulletins began circulating through confidential channels across the government around Thanksgiving. Those analyses said China's leadership knew the epidemic was out of control even as it kept such crucial information from foreign governments and public health agencies.
