Abstract
A syphilis outbreak began in Martinique, French Antilles, in 2004, initially among men who had sex with men (MSM) and who were living with human immunodeficiency virus (HIV). The outbreak subsequently affected all groups at risk, leading to a first epidemic peak in 2008. After an initial decrease, the outbreak started growing again in 2014 among patients living with HIV with unprecedented incidence among MSM. Herein, we describe the change in medical and social parameters of the outbreak since 2005.
