Following the publication of this article, the Editor-in-Chief and Publisher were alerted to concerns over terminology used, errors in the reference list, and unacceptable levels of similar text with a previously published paper: Deuba K, et al. Risk of HIV infection among men having sex with men in Kathmandu Valley, Nepal. Asia-Pacific Journal of Public Health. DOI: http://dx.doi.org/10.1177/1010539512441491.
The authors were contacted in relation to these concerns and provided timely, adequate answers to all issues raised. The authors admit and apologize for two major mistakes: the missing reference of Deuba et al; and the errors in the reference list. All other concerns were adequately answered.
In light of these, the Editor-in-Chief and Publisher are issuing this Expression of Concern to make readers aware of these points.
