Several commissions, appointed during the first quarter of this century to investigate the cause of pellagra, concluded from their studies that pellagra was an infectious, contagious disease. Harris (1913) was able to inject Berkefeld filtered tissue material from pellagra victims into monkeys to cause a corresponding disease in these animals. He concluded from these experiments that a virus was present in the injected material and that it was the cause of pellagra. If the work of Harris had been followed exclusively, various strains of this "virus" might have been discovered and a vaccine, effective in experimental animals, might have been developed, as in the case of poliomyelitis. Today, as a result of unlimited research, however, we know conclusively that pellagra is not caused by a virus but rather that it is a vitamin deficiency disease. It is obvious that if the investigations of pellagra had been restricted to the virus theory, it would still be a mystery.
....The general attitude of that period is expressed by Sachs (1911) in his statement: "In general, the epidemic occurrence of any disease is sufficient to prove its infectious or contagious character." The vitamin deficiency diseases, beriberi and pellagra, are outstanding examples of epidemic diseases that were formerly considered to be infectious and communicable according to the logic employed by Sachs. In fact, we find pellagra incorporated into the Public Health Law as a communicable disease in the State of Pennsylvania in the following rule and regulation adopted January 5, 1910: "That all physicians practicing within the limits of the state shall make immediate report of each and every case of uncinariasis duodenalis (hookworm disease) and pellagra and anterior poliomyelitis (infantile paralysis) occurring in their practice in the same manner that other communicable diseases are now by law and by rule and regulation of the State Department of Health reported to the health authorities.
