Infectious Diseases. —Of the common infectious diseases whooping-cough and measles, and also influenza except where pneumonic complications occur, are not notifiable. The notifiable diseases will be commented upon in a later section. Influenza was more prevalent in 1934 than in the previous year, and the number of deaths increased by 83 (from 103 to 186), the death-rate per 10,000 of mean population being 1-26, as compared with 0-70 in 1933. Whooping-cough, which caused 44 deaths in 1932, and only 18 in 1933, again increased in prevalence in 1934, and resulted in 40 deaths. This disease becomes epidemic every few years, the period between the main crests of the epidemic waves varying from three to four years, with a tendency during the past fifteen years for the period to lengthen. Measles, from which New Zealand had been markedly free from 1928, become epidemic in 1933 and caused 17 deaths. The epidemic started in the north, and reached Otago towards the end of that year. It persisted during 1934, 46 deaths resulting. Infant Mortality, 781. The infant-mortality rate for 1934 was 32-11 per 1,000 births.

Infant Mortality in New Zealand, 1929-34 (per 1,000 Live Births).

It will be seen from the above that there was a slight rise last year in the death-rate of infants.
