Smallpox Surveillance Reports

Last cases in Ethiopia

DA Henderson's working graph of cases in Ethiopia in the last stages of the eradication campaign, June-August 1976.

The Smallpox Surveillance Reports were issued about every 3 weeks beginning in June 1968. The series of 151 reports concluded in May 1980 with the World Health Assembly’s declaration that smallpox had been eradicated. The reports were reprinted from WHO's Weekly Epidemiological Record (see Related Archives). Most issues featured a brief overall summary and table, followed by a more detailed focus on a specific region, country, or practice (see list below). "Mid-year summaries" were prepared in early May for the annual May meetings of the World Health Assembly.

Tables supplementing the WER reports were added. These included tabulations of smallpox incidence by week and district for India (Report Nos. 42 – 118), Pakistan (Report Nos. 81 - 113), and Bangladesh (Report Nos. 81 - 123).
