AbstractThe high burden of syphilis in China presents a unique opportunity to examine temporal trends. This study used wavelet transformation and Fourier analysis to assess the presence of temporal oscillations in adult syphilis, gonorrhea, and congenital syphilis over 11 years in China's largest province. This study found a significant annual oscillation trend in adult syphilis cases, consistent with a peak during July-August-September, which was four-fold higher than January-February-March, the trough. A similar but dampened trend was observed for gonorrhea and no trend was observed for congenital syphilis. Further research on the temporal oscillation of syphilis cases is needed.
