Puerperal Septicæmia in New Zealand, 1918-22.
It is well known that the returns of notifications in puerperal septicaemia are, as a general rule, far from complete. The marked rise in the notification-rate for 1921 and 1922, therefore, does not necessarily indicate an increased prevalence of the disease for these years, but represent rather an increased observance of the laws regarding notification. The returns of deaths provide a more accurate presentation of the position. The fact that 1922 has the second-lowest death-rate of the series is so far satisfactory, although there is no ignoring the fact that New Zealand occupies an unfavourable position as regards this disease in comparison with other countries.
