The stress of worrying about Jughashvili, as well as the isolation and warm climate took a toll on her health, and Svanidze soon fell ill. According to a friend, Stalin said at her funeral that she had softened his heart of stone. Her brother Alexander was a confidant of Stalin, then still known by his birth name of Ioseb Jughashvili, and introduced him to Svanidze in 1905. The family moved to Baku to avoid arrest, though Svanidze got quite ill there and returned to Tiflis in 1907, dying shortly after her return, likely from typhoid or tuberculosis. Kato Svanidze was the first wife of Joseph Stalin and the mother of his eldest son, Yakov. Her brother Alexander Svanidze was a revolutionary and a friend of the young Ioseb Jughashvili, later known as Stalin. Kato married Jughashvili in July 1906 in a secret Orthodox church ceremony in Tiflis, since he was wanted by the police. Jughashvili was often away on revolutionary work, and Kato fell ill with typhus. Kato died in Tiflis on December 5, 1907.

It gives no dependable sequence of treatment and last symptoms from which to reconstruct a more detailed bedside narrative.
