Correction to: BMC Infect Dis

https://doi.org/10.1186/s12879-020-4881-7

After publication of the original article [1], there is a duplicate “35.22” in the section “Study outcomes”: Secondary outcomes included combined aortic valve repairs or replacements (ICD-9 35.11, 35.22, 35.22), […]”. This should be read “(ICD-9 35.11, 35.21, 35.22)”, instead.

The original article has been corrected.
