In 1957 I was stationed at the 6th Army Medical Laboratory at Ft. Baker, California as Chief of the Immunology Division. The division provided viral diagnostic services to all military (Army, Navy, Air Force) medical facilities within the area plus Alaska and Hawaii. At that time, we employed the hemagglutination – inhibition test procedure for influenza diagnosis using four antigens – Type A (PR8), Type A’ (FM1), Type B (Lee) and the isolate for the current year, which in this case we identified as Baker 1 (Type A). We had recovered the latter strain from an individual stationed at Ft. Baker. We produced these antigens in embryonate chicken eggs. Upon being apprised of the evolving pandemic, we added the pandemic strain which was provided by the CDC.
Because of the volume of specimens being submitted we limited testing to paired specimens; i.e., an acute sample obtained within 5 days of onset and a convalescent sample collected 10 or more days later. Even with this “restriction,” we were testing 20 pairs per day, 6 days per week – this being accomplished by eight individuals (technical and support). To the best of my recollection, we tested approximately 1500+ pairs of which some 60% were positive for the “pandemic strain”.
Another event with the USPHS involved a commercial cruise ship returning to San Francisco from the Far East on which a passenger had died as the result of pneumonia. The ship was anchored at the Quarantine Station in San Francisco Bay. The media in San Francisco boarded water taxis and circled the ship, attempting to get “the shot of the year”. It was determined that the passenger had pneumonia when she boarded in Manila and that she had remained in her cabin. Whether she may also have had influenza could not be determined.
