Jail fever

A'LTHO this Fever neither arose in a Jail, nor a Hospital, yet it so exactly re-sembles the Jail Fever, both in the symptoms, causes, and method of cure, that I have not scrupled to treat of it under that name.

I have now the satisfaction to see this opinion confirmed, in so far at least as relates to the dysentery, a putrid disease, equally contagious with the jail fever, and in military hospitals, at least, still more fatal.

John Pringle’s army service in the 1740s convinced him that an assortment of illnesses attributed to an unhealthy environment—“jail fever,” “camp fever,” “ship fever” and “putrid fever” —were in fact the same disease, generated by crowding but transmitted by contagion.
