The final outbreak

The last major outbreak of the disease occurred in England in 1551. An eminent physician, John Caius

, wrote an eyewitness account of the disease at this time called A Boke or Counseill Against the Disease Commonly Called the Sweate, or Sweatyng Sicknesse.

Characteristics

The symptoms and signs as described by Caius and others were as follows: The disease began very suddenly with a sense of apprehension, followed by cold shivers (sometimes very violent), giddiness, headache and severe pains in the neck, shoulders and limbs, with great exhaustion. After the cold stage, which might last from half an hour to three hours, the hot and sweating

 and pain in the heart were frequent symptoms. No skin eruptions were noted by observers including Caius. In the final stages, there was either general exhaustion and collapse, or an irresistible urge to sleep, which Caius thought to be fatal if the patient was permitted to give way to it. One attack did not offer immunity

, occurred in France between 1718 and 1861, but was less likely to be fatal. It was accompanied by a rash, which was not a feature of the earlier outbreaks.

Cause

The cause is the most mysterious aspect of the disease. Commentators then and now put much blame on the generally poor sanitation, sewage and contaminated water supplies of the time, which may have harboured the source of infection. The first outbreak at the end of the Wars of the Roses

But, relapsing fever is marked by a prominent black scab at the site of the tick bite and a subsequent skin rash. No contemporaries noted these relatively obvious signs, so the identification is far from certain.
