RESUMO
Chlamydia trachomatis and Mycoplasma genitalium are two common types of sexually transmitted infections. However, currently in Vietnam, there is no report on the rate of patients infected by the two types of bacteria. In this study, there were 6194 patients visiting the STI clinic of the HCMC Hospital of Dermato-Venereology, Vietnam, from 2016 to 2019. The results show that the proportion of patients positive with CT and MG is in-dependent on time. The infection rate is mainly at the age of 21 - 30 (53.4%). The CT infection rate in female and male is equal (17.3% vs 17.4%) while the rate of MG in female is lower (5.1% vs 7, 8%). The rate of pa-tients co-infected with either CT or MG is 4.5%, 17% and 5.7% respectively, time independence. This study may give better understandings of the epidemiological characteristics of MG and CT in Vietnam.
