1. Angola and Mozambique were not independent states until 1975—they were Overseas Protectorates of Portugal. Both had been engaged in engaged in civil wars for independence since the early 1960s. Contact had to be made through the health authorities in Lisbon, where smallpox eradication was of little significance.
2. Botswana, which had last reported cases in 1964, experienced a major epidemic beginning in 1972 but interrupted transmission in 1973.
3. The Democratic Republic of the Congo was renamed Zaire in 1971, and changed back to the Democratic Republic of the Congo in 1997.
4. South Africa, a WHO Member State, had been deprived of its WHO voting rights and services in 1964. It stopped its annual contribution and its attendance at the World Health Assembly. Communication between South Africa and WHO all but ceased. Because South Africa administered Namibia (South-West Africa until 1968), communication with that jurisdiction was also affected.
5. Southern Rhodesia, administered by the United Kingdom, was an Associate Member of WHO represented by the UK until 1965, when its WHO rights were suspended on UK initiative. Official communication had to conducted through London, but there was little official contact between the UK and Southern Rhodesia. Southern Rhodesia was renamed Zimbabwe when it became indenpendent in 1980.
