Comby found that in Paris only the new-born were noticeably insusceptible to influenza, that children up to 15 years were attacked in the proportion of 40 per cent., and adults in the proportion of 60 per cent. Danchez believed that in families in which all the adults became ill, the little children usually escaped. Finkler states that in the schools at Bordeaux the older children were first and most frequently attacked. Of the 248 male and female teachers in 41 schools, 153 (61.7 per cent.) developed the disease. Children up to five or six years of age at any rate seem to have been very little affected, while older children were no less susceptible than adults. Among 47,000 cases of influenza treated by physicians in Bavaria in 1889, the various ages were as follows: 1 year 1.5 per cent. 2–5 5.4 per cent. 6–10 6.6 per cent. 11–15 7.2 per cent. 16–20 11.4 per cent. 21–30 22.2 per cent. 31–40 19.3 per cent. 41–50 12.6 per cent. 51–60 7.7 per cent. 61–70 3.6 per cent. 71–80 2.0 per cent. Above 80 0.5 per cent. Leubuscher recorded that in Jena the proportion of cases in the individual age classes did not correspond with the figures reported from other localities. Children, and especially very young children, suffered relatively less than adults. The following statistics of the 1889–90 incidence of influenza among school children in Cologne were collected by Lent: Attendance. Ill of influenza. Class I–13 to 14 years of age 3,002 1,015 33.8 per cent. Class II–11 to 12 years of age 5,737 1,835 31.9 per cent. Class III–10 years of age 3,701 1,130 30.5 per cent. Class IV– 9 years of age 3,590 930 25.9 per cent. Class V– 8 years of age 2,929 822 28.0 per cent. Class VI– 7 years of age 3,388 758 22.3 per cent. These may be compared with figures for the public schools in the suburbs of Cologne: Attendance. Ill of influenza. Class I–13 to 14 years of age 1,609 689 42.9 per cent. Class II–11 to 12 years of age 2,885 1,094 37.9 per cent. Class III–10 years of age 1,683 626 37.1 per cent. Class IV– 9 years of age 1,758 552 31.4 per cent. Class V– 8 years of age 1,771 502 28.2 per cent. Class VI– 7 years of age 1,938 510 26.3 per cent.
