Otaqo and Southland District Infectious Disease. The tables on the following pages show the incidence of infectious disease. One of the larger outbreaks of the year was an epidemic of diphtheria at (lore in November and December, when 22 cases, including one death, occurred among the population of 3,500, the cause of the outbreak being undiagnosed mild cases in the main public school. I examined a considerable number of the school-children, and arranged with the medical men to send swabs to laboratory for report. The enforcing of precautions, together with the closing of the school soon after for the midsummer holidays, stopped the outbreak. Seven cases of enteric, including three deaths, took place in March in the small inland township of Heriot, originating from one case in which tin proper precautions were taken. Five cases of enteric also occurred in January in connection with a small sheep-station at the head of Lake Wanaka. Several cases occurred during the second quarter of the year in various parts of the district, some of which were traced to eating infected oysters, the outcome of which being an exhaustive report by Inspector Cameron mi the oyster-storage platforms at the Bluff.
