Following publication of the original article [1], it was reported that the text did not contain reference to the NCBI GenBank entries of the proviral genome sequences determined in this study.

The ‘Availability of data and materials’ declaration should include the statement "Proviral genome sequences are available from GenBank (accession numbers KU720628 [case 1], OM339153 [case 2], OM339154 [case 3], OM339155 [case 4], OM339156 [case 6], OM339157 [case 7] and OM339158 [case 5]."

The original article [1] has been corrected.
