Plague years force pastoral triage and visitation rules in Geneva
In early-1540s plague years Geneva’s pastoral corps under Calvin’s system faced visitation rules and triage while infection killed residents. In the causal graph this event strengthens Infectious-Disease Transmission, a driver that weakens Life expectancy at birth — a worsening welfare path.

Read the full account
In early-1540s plague years Geneva’s pastoral corps under Calvin’s system faced visitation rules and triage while infection killed residents. The instrument is that plague-ministry crisis, not a claim that he caused the disease.
Context
Epidemic and church office meet. Reformation Museum and Britannica independently place plague among Geneva’s early Reformed crises.
John Calvin’s documented role is bounded by other offices and collaborators named in the sources below.
Conventional years are 1509–1564. Surviving public files are later museum pages, consistory editions, Meeter Center collections, and encyclopedias. Calvin did not typeset those later pages.
Why it matters
Infectious-disease path. High confidence on plague presence; medium on any one visitation rule’s unique minute.
Who was responsible

What the sources establish
The Reformation Museum and Britannica independently note plague crises in early Reformed Geneva.
Established: plague struck Geneva in the early Ordinances years with pastoral involvement. Not established: that Calvin discovered contagion theory.
John Calvin did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. Plague ministry is not Consistory dancing fines. Keep infection off the sumptuary row.
