The Twenty-Sixth World Health Assembly in 1973 amended the IHR (1969) in relation to provisions on cholera. In view of the global eradication of smallpox, the Thirty-fourth World Health Assembly amended the IHR (1969) to exclude smallpox in the list of notifiable diseases. During the Forty-Eighth World Health Assembly in 1995, WHO and Member States agreed on the need to revise the IHR (1969). Several challenges were placed against the backdrop of the increased travel and trade characteristic of the 20th century. The revision of IHR (1969) came about because of its inherent limitations, most notably: narrow scope of notifiable diseases (cholera, plague, yellow fever). The past few decades have seen the emergence and re-emergence of infectious diseases. The emergence of “new” infectious agents Ebola Hemorrhagic Fever in Zaire ( modern- day Democratic Republic of Congo) and the re-emergence of cholera and plague in South America and India, respectively; dependence on official country notification; and lack of a formal internationally coordinated mechanism to prevent the international spread of disease.
