World Health Organisation leaflet about smallpox, 1970-1 (pre-decimal marked 6/-)
This leaflet shows in photographs the different stages of the disease and how long each stage of the disease lasts. Chickenpox was included in the leaflet as the two diseases can appear to be similar to the untrained eye. This leaflet was used in Africa during the World Health Organisation’s (WHO) smallpox eradication campaign. Success was achieved in 1979.
