When the agency is undisclosed or partially disclosed, however, both the agent and the principal are liable. Where the principal is not bound because the agent has no actual or apparent authority, the purported agent is liable to the third party for breach of the implied warranty of authority.
The International Classification of Diseases (ICD) is the standard diagnostic tool for epidemiology, health management and clinical purposes. This includes the analysis of the general health situation of population groups.
The first international classification edition, known as the International List of Causes of Death, was adopted by the International Statistical Institute in 1893. WHO was entrusted with the ICD at its creation in 1948 and published the 6th version, ICD-6, that incorporated morbidity for the first time.
