Some data cleaning was performed:
East Pakistan was changed into Bangladesh and West Pakistan was changed into Pakistan.
Upper Volta was changed into Burkina Faso, Southern Rhodesia to Zimbabwe, Ceylon to Sri Lanka but Dahomey (a region in today's Nigeria) was left as it is.
For all countries that approached zero cases and then were not included in the Weekly Epidemiological Record (WER) anymore subsequently were assumed to have zero cases. This was done for 1967-1977.
