of home-treated patients compares with the comparative rate of
27 per cent. for patients treated in hospital during the same period.
Contact Attack Rate During Period of Isolation.
Table 7 shows the results of a statistical analysis of the occurrence
of secondary cases among Leyton contacts during the six-year
period 1932-37. It shows not only the risk to all contacts and to
contacts of three different age groups, but also the risk during
the first week as compared with that during the remaining weeks
of isolation. As it was found impossible to form any reliable
estimate of the number of contacts or primary cases occurring in
institutions, these cases have been omitted from the analysis, which
deals only with cases of scarlet fever notified from private houses
in Leyton.
