They all subsequently die from syphilis, their families never told that they could have been treated.

1935  The Pellagra Incident. After millions of individuals die from Pellagra over a span of two decades, the U.S. Public Health Service finally acts to stem the disease.

1985  According to the journal Science (227:173-177), HTLV and VISNA, a fatal sheep virus, are very similar, indicating a close taxonomic and evolutionary relationship.

1986  According to the Proceedings of the National Academy of Sciences (83:4007-4011), HIV and VISNA are highly similar and share all structural elements, except for a small segment which is nearly identical to HTLV. This leads to speculation that HTLV and VISNA may have been linked to produce a new retrovirus to which no natural immunity exists.
