Sub-clinical Attacks

Sub-clinical Attacks

All figures of case incidence are to some extent inaccurate because of the large numbers who had sub-clinical attacks, as will be described later. These being of all grades of severity, many could not be located as they did not report sick. However, it is clear that among New Zealand troops the incidence must have been much higher than is indicated by figures.
