The most important provision, however, relating To infectious disease is that contained in the Infectious Disease Notification Act 1889.
The duty of notification is imposed upon the head of the family, and also upon the medical practitioner who may be in attendance on the patient.
The Shan States were declared to be a part of British India by notification in 1886.
It also provides that the existence of a state of war must be notified to the neutral powers and shall not take effect in regard to them until after the receipt of the notification which may be given by telegraph.
Most of the good effect of the provision, however, is negatived by the qualification that neutral powers cannot rely on the absence of notification if it is clearly established that they were in fact aware of the existence of a state of war.
