We analyzed prevalence rates of syphilis (positive Treponema pallidum hemagglutinin antigen/T. pallidum particle antigen and venereal disease research laboratory test) among police officers in Guinea-Bissau from 1990 to 2010 and found a significant decline from 4.5% to 0.4% (P = 0.0065). Our results are in line with other recent reports from West Africa. More research is needed to identify the reasons for this decline.
A study of police officers in Guinea-Bissau found a significant declining syphilis prevalence trend in 1990 to 2010.
