The Red Rust is a virus where victims "cry themselves to death".

Fiction

IDW comics continuity

An outbreak of this disease struck Delphi and contaminated its inhabitants. This caused First Aid, Pharma, and Ambulon to treat those who were infected. After awhile, Ratchet, Pipes, and Drift came to investigate and First Aid informed them of the crisis. As they proceeded with their exploration, Drift and Pipes were contaminated by the virus. Life After the Big Bang

The disease was cured by Ratchet once he received the vaccine from the traitorous Pharma who had originally caused the outbreak to escape a deal he had made with the Decepticon Justice Division. How Ratchet Got His Hands Back
