Abstract
Cassava brown streak disease (CBSD) is currently the most devastating cassava disease in eastern, central
and southern Africa affecting a staple crop for over 700 million people on the continent. A major outbreak
of CBSD in 2004 near Kampala rapidly spread across Uganda. In the following years, similar CBSD
outbreaks were noted in countries across eastern and central Africa, and now the disease poses a threat
to West Africa including Nigeria - the biggest cassava producer in the world. A comprehensive dataset
with 7,627 locations, annually and consistently sampled between 2004 and 2017 was collated from
historic paper and electronic records stored in Uganda. The survey comprises multiple variables including
data for incidence and symptom severity of CBSD and abundance of the whitefly vector (Bemisia tabaci).
This dataset provides a unique basis to characterize the epidemiology and dynamics of CBSD spread in
order to inform disease surveillance and management. We also describe methods used to integrate and
verify extensive field records for surveys typical of emerging epidemics in subsistence crops.
