A specific real-time polymerase chain reaction followed by melt curve analysis was developed for the detection of the Swedish variant (nvCT) strain of Chlamydia trachomatis (CT). Surveillance was performed on 476 CT-positive clinical specimens obtained from 15 laboratories around the United States using nucleic acid amplification test assays, which would not miss the nvCT. All were negative for nvCT; thus, there is no evidence of the nvCT in the United States.
