About this time in autumn, towards the end of September, there began and reigned in the city, and other parts of the kingdom, a disease then new: which by the accidents and manner thereof they called the sweating sickness. This disease had a swift course, both in the sick body, and in the time and period of the lasting thereof; for they that were taken with it, upon four and twenty hours escaping, were thought almost assured. And as to the time of the malice and reign of the disease ere it ceased, it began about the one-and-twentieth of September, and cleared up before the end of October, insomuch as it was no hindrance to the king's coronation, which was the last of October; nor, which was more, to the holding of the parliament, which began but seven days after. It was a pestilent fever, but, as it seemeth, not seated in the veins or humours, for that there followed no carbuncle, no purple or livid spots, or the like, the mass of the body being not tainted; only a malign vapour flew to the heart, and seized the vital spirits; which stirred nature to strive to send it forth by an extreme sweat. And it appeared by experience, that this disease was rather a surprise of nature than obstinate to remedies, if it were in time looked unto. For if the patient were kept in an equal temper both for clothes, fire, and drink, moderately warm, with temperate cordials, whereby nature's work were neither irritated by heat, nor turned back by cold, he commonly recovered. But infinite persons died suddenly of it, before the manner of the cure and attendance was known. It was conceived not to be an epidemic disease, but to proceed from a malignity in the constitution of the air, gathered by the predispositions of seasons; and the speedy cessation declared as much.This disease made five further appearances in 1506, 1517, 1528, 1551, and 1578. It was confined to England, except in 1528-29, when it is said to have spread to the European continent, appearing in Hamburg and passing northward to Scandinavia and eastward to Lithuania, Poland, and Russia; the Netherlands also were involved, but the disease did not spread to France or Italy. It never spread across the Scottish border and there is only one certain record of it in the Irish Annals:
A. D. 1528. A pestilential sickness, called the English sweat, which first appeared in Ireland in 1491, now again raged with great violence, and at Dublin swept away archbishop Inge, lord chancellor, William Talbot, Richard Elyot, Richard Fitzwilliams, Walter Fian, and two canons Luett, with Stanihurst, and great numbers of other citizens.The reference to 1491 is not supported by other data and the fact that this does not correspond with an appearance in England suggests that it may have been something else. It generally became known as the Sweating sickness but was also dubbed sudor anglicus or the English Sweat because it appeared to affect only English people. It remains one of the unsolved mysteries of historical epidemiology.

"They which had this sweat sore with peril of death were either men of wealth, ease or welfare, or of the poorer sort, such as were idle persons, good ale drinkers and taverne haunters."Surviving the disease conferred no immunity - Cardinal Wolsey is reported to have survive no fewer than three successive attacks. Another famous sufferer was Ann Boleyn who wrote the following letter to Wolsey during here recuperation:
"My lord,
In my most humble wise that my poor heart can think, I do thank your grace for your kind letter, and for your rich and goodly present, the which I shall never be able to deserve without your help, of which I have hitherto had so great plenty, that all the days of my life I am most bound of all creatures, next the king's grace, to love and serve your grace, of the which I beseech you never to doubt that ever I shall vary from this thought, as long as any breath is in my body. And as touching your grace's trouble with the sweat, I thank our Lord that them I desired and prayed for are escaped; and that is the king's grace and you, not doubting that God has preserved you both for great causes known alonely of His high wisdom. And as for the coming of the legate, I desire that much. And if it be God's pleasure, I pray him to send this matter shortly to a good end; and then I trust, my lord, to recompense part of your great pains. In the which I must require you, in the mean time, to accept my goodwill in the stead of the power; the which must proceed partly from you, as our Lord knoweth, whom I beseech to send you long life, with continuance in honor. Written by the hand of her that is most bound to be your humble and obedient servant,
Anne Boleyn."In contrast to other epidemics such as the plague and the smallpox, which moved steadily through a population, the Sweat darted here and there and struck completely at random. This only added to the terror already heightened by its incredibly swift course. Although it was devastating in local populations, it had no major impact on the overall demographics of the country. The panic in 1485 resulted in the abandonment of the University at Oxford which was shut down for six weeks. It also frustrated Henry VII, whose claim to the throne was very tenuous, as his coronation had to be postponed. However the pestilence went as rapidly as it had arrived and had completely disappeared five weeks later. The coronation duly took place in Westminster Abbey on October 31st 1485. To the naturally superstitious mind of the period, this sudden appearance of a new and terrifying disease at the beginning of a reign was seen as a very bad omen which h only served to underline Henry's weak claim. His position was bolstered by a hastily passed Act of Parliament which declared that the inheritance of the Crown had come as of right to him and the heirs of his body. He also had the support of Pope Innocent III who threatened to excommunicate anyone who challenged Henry's legitimate kingship.

"Both diseases are carried by a rodent and occur in rural environments in summertime. Unlike many other viruses that hit elderly populations hardest, these two diseases kill healthy adults. Most striking, however, is the rapid deterioration of the patient. Victims suffer from flu-like symptoms that progress to severe respiratory and cardiac difficulty. Hantavirus causes the lungs to fill with fluid and leaves people gasping for air in the same way that sweating sickness left its victims breathless.However, there are problems with this identification also. If the Sweating Sickness had been a hantavirus isolated cases would still occur in England and there has never been a report of this virus in Britain. The nature and origin of the sudor anglicus is a medical mystery and has every appearance of remaining so.
