Medical historians have never known what caused the sweating sickness. That the disease was neither plague nor typhus was clear from contemporary accounts. Its victims bore neither the boils typical of plague nor the rash of typhus. Now physicians Vanya Gant and Guy Thwaites, both of St. Thomas’ Hospital in London, think they may have identified the killer. Sudor Anglicus, they say, may have been an early version of a disease that has made headlines in recent years: hantavirus pulmonary syndrome, which erupted in the Four Corners region of the American Southwest in the summer of 1993.
The similarities between the two are striking, says Gant. First, there is hanta’s rapid course. Basically, you’ve got a headache in the morning, you’re short of breath in the afternoon, you take to your bed at teatime, and you’re on a respirator by midnight, he says. Second, sweating sickness left its victims breathless. Hanta also leaves people gasping, filling their lungs with fluid.
Perhaps most suggestive of a common identity for the two diseases is that each epidemic of sweating sickness appeared in the summer and often in rural areas, meaning that a rapidly breeding rodent may have been its primary host; hanta’s main refuge is the deer mouse. Finally, the sweating sickness typically killed robust adults, just as hanta does. Most flu viruses, on the other hand, strike hardest at the elderly.
Gant and Thwaites say they could conceivably test their hypothesis. Henry Brandon, duke of Suffolk, who succumbed during the epidemic of 1551, was buried in a cemetery that still exists. It would be possible to exhume the body and search for hantavirus rna. Unfortunately, this type of genetic material is unstable and the odds of its survival low, so the researchers have no plans to disturb the duke’s grave. Even without sixteenth-century hantavirus in hand, though, Gant believes there’s little room for doubting the true identity of the Tudor disease. People should not be blind to the possibility that things that are hailed as new may well be what has always been here.
