11 – CDC receives the second group of isolates


12 – double immunodiffusion confirms two original untyped viruses are a type of influenza A; hemagglutinin inhibition tests indicate four of the Fort Dix isolates contain swine flu type hemagglutinin; CDC lab communicates this finding to Sencer in the evening


12 – Goldfield telephones virologist Dr. Edwin Kilbourne of Mt. Sinai Hospital in New York City with the news that he possesses a virus he cannot type; Kilbourne asks Goldfield to send him some specimens


13 – N.J. lab mails quantity of the Fort Dix virus to Kilbourne


13 – scientists at CDC confirm that the isolates are indeed swine-type influenza A viruses; at Sencer's request, Dr. Walter Dowdle, head of CDC's labs, notifies scientists and health officials across the country of the A swine discovery, and invites them to a meeting at CDC the next day


14 – emergency meeting is held at CDC to discuss the Fort Dix finding; in attendance are representatives of the Army (Dr. Philip Russell, Dr. Frank Top), the New Jersey Department of Health (Goldfield), FDA's Bureau of Biologies (Dr. Harry Meyer, Jr.), NIH's National Institute of Allergy and Infectious Diseases (Dr. John Seal), and CDC (Sencer-chairman, Dull, Dr. William Foege, Noble, Dr. Michael Hattwick, Dowdle, Dr. Alan Kendal); conferees discuss need to develop vaccine; also decide not to publicize swine virus finding


14-16– CDC reconfirms isolation and identification of swine flu virus from original throat swabs brought from N.J. Health Dept.


16 – Sencer and Dowdle inform Dr. Charles Cockburn of the World Health Organization (Geneva) of swine virus finding; Dowdle informs Kilbourne


17 – Kilbourne receives samples of the virus mailed from New Jersey; his lab begins to develop a fast-growing "recombinant" for use in vaccine


18 – CDC notifies state health officials of swine flu finding


19 – CDC calls press conference; Dull announces swine virus has been discovered at Fort Dix; makes no reference to the 1918 pandemic in his prepared remarks, but does in response to questions from reporters


20 – first media coverage of swine flu focuses on CDC's announcement of the previous day; coverage links the Fort Dix virus to the 1918 pandemic


20 – BoB hosts open workshop in Bethesda, Maryland, with representatives from the Armed Forces Epidemiological Board (AFEB), NTAID, CDC, the press, the scientific community, and all four vaccine manufacturing companies; conferees discuss preparations for a swine flu immunization campaign; second meeting held in the afternoon to discuss surveillance plans
