  abstract = {{S}weetpotato ({I}pomoea batatas) production in sub-{S}aharan {A}frica is severely affected by viral diseases caused by several interacting viruses, including sweet potato feathery mottle virus ({SPFMV}), sweet potato chlorotic stunt virus ({SPCSV}), and sweet potato leaf curl virus ({SPLCV}). {H}owever, the aetiology of viral symptoms on sweetpotato is rarely established in most countries in {A}frica. {H}ere, we aimed to investigate and characterize the incidence of sweetpotato viruses in {B}urkina {F}aso. {W}e performed a countrywide survey in 18 districts of {B}urkina {F}aso and collected 600 plants, with and without symptoms, from 80 fields. {V}iral strains were identified using nitrocellulose membrane-{ELISA}, {PCR}, and reverse transcription-{PCR}. {T}hree scions from each of 50 selected plants with symptoms were grafted to healthy {I}pomoea setosa and then serological and molecular tests were performed on the 150 recorded samples. {T}hree viruses were detected: 24% of samples were positive for {SPFMV}, 18% for {SPLCV}, and 2% for {SPCSV}. {A}cross all diagnostic tests, 40% of all plant samples were virus-negative. {C}oinfections were found in 16% of samples. {P}artial sequences were obtained, including 13 that matched {SPFMV}, one that matched {SPLCV}, and one that matched {SPCSV}. {A}ll identified {SPFMV} isolates belonged to either phylogroup {B} or {A}-{II}. {T}he {SPCSV}-positive isolates had 98% gene sequence homology with {SPCSV}-{W}est {A}frica for the coat protein. {B}egomovirus-positive isolates clustered with {SPLCV}-{U}nited {S}tates. {T}his first study of sweetpotato viral diseases in {B}urkina {F}aso indicates widespread occurrence and suggests a need for further epidemiological investigations, breeding programmes focused on virus-resistant varieties, and improved farming practices to control disease spread.},
