Tuberculosis, the White Plague, was the leading cause of death in nineteenth-century America and had no cure for sixty years after the germ was found. The fight ran largely outside Washington, through Edward Trudeau's sanatorium, the Christmas Seal, and housing reform, until streptomycin emptied the sanatoria in the 1940s and 1950s. The federal service was a supporting player, not the lead.
The 'one in seven deaths' figure varies by period and source, and sanatoria improved odds without curing, as TB declined before antibiotics. Albert Schatz sued over credit for streptomycin, which Waksman received the Nobel for.
