In Austria, "The most prevalent virus was DWV, present in 91% of samples,
followed by ABPV, SBV, and BQCV (68%, 49%, and 30%, respectively). CBPV was
detected in 10% of colonies, while KBV was not present in any sample."

France: "DWV
was recorded in 97%, SBV in 86%, BQCV in
86%, ABPV in 58%, CBPV in 28% and KBV
in 17% of apiaries (Tencheva et al., 2004)."

Viral distribution is reviewed by Nielson in Denmark Apidologie 39 (2008)

Interestingly, in South Africa, Dr Mike Allsopp found very few viruses in
feral colonies.
