Perhaps the most unexpected revelation of typhus is at Chester, from the time when Haygarth began to write upon its public health in 1772. Chester was then one of the most desirable places of residence in England. Boswell wrote to Johnson, “Chester pleases me more than any town I ever saw.” The old city within the walls was occupied by a superior class of residents, including the cathedral clergy, county families, retired officers and Anglo-Indians, professional men, merchants and tradesmen. It had the best theatre out of London. Squares, crescents and broad streets were replacing most of the old buildings. The six parishes that lay entirely within the walls had a population, in 1774, of 3502, and an annual average death-rate (in the ten years 1764 to 1773) of 1 in 58 or 17·2 per 1000, the central parish of St Peter having a rate of 1 in 62, and the cathedral parish 1 in 87. It passed as one of the healthiest cities in the kingdom, being far before Shrewsbury and Nottingham, to say nothing of the large towns where the burials exceeded the baptisms. But its moderate death-rate over all, 1 in 42 living, would have been much lower but for the four poor suburban parishes, with a population of 11,211, which had a death-rate of 1 in 35. Haygarth gives a deplorable account of them. The houses were small, close, crowded and dirty, ill supplied with water, undrained, and built on ground that received the sewage from within the walls. The people were ill-fed and they seldom changed or washed their clothes; when they went abroad they were noisome and offensive to the smell. Many of them worked on the large farms around Chester, others at shipbuilding and shipping (Chester had then a considerable foreign trade), others at the mills and markets, others at a nail-factory, while others were employed by the tradesmen within the walls. Fever seems to have been perennial among them, the deaths from typhus having been 23 in 1772, 33 in 1773 and 35 in 1774. “In these poor habitations,” says Haygarth, “when one person is seized with a fever, others of the family are generally affected with the same fever in a greater or less degree.” It became rifer than usual in August, 1773, and attacked 285, proving fatal to 28, or to one in ten. It had the common symptoms of malignant fevers produced by human effluvia, and particularly affected the head with pain, giddiness and delirium. It attacked in general the lowest, few of the middle rank, and none (or only one) of the highest rank[254].
