The epidemic became rapidly prevalent all over England, Scotland and Ireland in April and May, following no very definite order of progression. The Liverpool newspapers asserted that ten thousand were down with it in that town in one week. A doctor at Lincoln wrote, on 13 May, that few families there had escaped it[722]. Other towns in which it is said to have been “more or less” prevalent were Portsmouth, Sheffield, Birmingham, Leeds, York, Halifax, Glasgow, Edinburgh[723], Dublin and Armagh; so that we may fairly assume, although we are without the detailed evidence available for earlier epidemics, that it was ubiquitous in town and country.
At Birmingham[724], among the outpatients of the Infirmary, the cases of influenza were as follows, the 25th and 26th April being the days when cases came first in rapid succession, while the middle of May was practically the limit:
| Cases of Influenza | Males | Females | ||||
| April | 151 | 52 | 99 | |||
| May | 464 | 159 | 305 | |||
| June | 28 | 9 | 19 | |||
| 643 | 220 | 423 | ||||
The great excess of females is remarkable, but was probably due to some local circumstances. Of the 643 cases, 122 were under ten years of age. Of the females, 9 died, of the males 3. But the deaths in Birmingham caused by the epidemic directly or indirectly were many; the burial registers of four churches and chapels showed a marked increase of burials above those of the corresponding months of 1832:
| 1832 | 1833 | |||
| April | 205 | 245 | ||
| May | 211 | 434 | ||
| June | 193 | 230 | ||
| 609 | 909 | |||
Medical opinion in 1833 was decidedly adverse to the contagiousness of influenza. The common remark was that it was just as little contagious as the cholera of the year before had proved to be. As in 1837 and 1847, when the doctrine of contagiousness was equally out of favour, the disease was observed to spread rapidly, in no very definite line, affecting most parts of the country in the same two or three weeks, affecting the population within a considerable radius almost at once, and the inmates of houses all together. These, it was said, are not the marks of a disease that persons hand on one to another, quasi cursores.
The Influenza of 1837.
Between the influenza of April-May, 1833, and that of January-February, 1837, it seems probable that there were minor catarrhal outbreaks, distinguishable from ordinary colds. One writer on the influenza of 1837 refers to those “who had it in 1834 or in the intervening period between the two epidemics.” The table of diseases of the outpatients at the Birmingham Infirmary for the year 1836 contains a large total of catarrhs, and, in another line, 24 cases of “epidemic catarrh” in the summer months. The Gentleman’s Magazine begins its notice of the epidemic of 1837 by calling it “an influenza of a peculiar character,” which shows that influenza of the ordinary kind was a familiar thing. Probably the name was a good deal misapplied in the years following every great epidemic from 1782 onwards: thus in ‘St Ronan’s Well,’ which was written in 1823, or twenty years from the last general influenza, a tradesman’s widow in easy circumstances and given to good living comes to the Spa on account of a supposed malady which she calls the influenzy. But our recent experiences of four great influenza seasons in succession from 1889-90 to 1893, although it is without precedent in the history, will incline us the more to credit what is recorded of influenza cases in the intervals between the years of great historical epidemics[725]. However that may be for the years following 1833, the influenza of January, 1837, was sudden, simultaneous, universal.
The first cases, which Watson compares to the first drops of a thunder-shower, were seen earlier in some places than in others; but from all parts of England it was reported that the influenza was at its height from the middle of January to the end of the first week of February. Possibly it was a few days earlier in London than in most other towns, inasmuch as the great increase of the deaths that is shown in the following table, in the second and third weeks of January, would imply a prevalence of the epidemic for at least a fortnight before.
