AYhooping-cough, 33; Measles, 2. Neither of these two diseases is compulsorily notifiable. Whooping-cough was prevalent, but the number of deaths caused thereby was low in comparison with former epidemics. Typhoid or Enteric Fever, 7. The position as regards this disease for the period 1926-30 is shown in the table below.

Enteric Fever in New Zealand, 1926-30.

It is also of interest to state that the death-rate from typhoid fever (average) for the last five years was approximately forty times less than a similar average taken fifty years ago. SECTION 3. Infant Mortality, 924. The infant-mortality rate for 1930 was 34-48 per 1,000 births.

Infant Mortality in New Zealand, 1926-30 (per 1,000 Live Births).

It will be seen from the above table that there was a reduction last year in the death-rate of infants over one month of age, but as regards those under 1 month of age the slight reduction in the death-rate shown in recent years was not maintained last year. Analysis of Deaths of Infants under One Month of Age, 1930. The following table gives the causes of these deaths during the year : —

Thus 512 of a total of 644 infant deaths in the first month of life occurred during the first week, and may be regarded as mainly due to pre-natal influences. It is also of interest to record that well over half of the infant deaths (in the first twelve months of life) occurred in this first week—i.e., 512 in a total of 924.
