Clinical and Sociodemographic Characteristics of Patients with Mpox Virus Treated at a Family Medicine Unit

Objective: To describe the clinical and sociodemographic characteristics of patients with Mpox virus treated at a family medicine service. Methods: A descriptive cross-sectional study was conducted. A search was performed in the electronic medical record database for patients with a PCR-confirmed diagnosis of Mpox virus infection who were treated at the Family Medical Unit No. 28 “Gabriel Mancera” of the Mexican Social Security Institute (IMSS) in Mexico City during 2022. Clinical and sociodemographic data, as well as comorbidities, were extracted. Descriptive statistics were per- formed. Results: A total of 51 patients were included, 98% (n= 50) were male, 95% (n= 49) were men who have sex with men (MSM), mean age 36 years (± 9.3); 80% (n= 41) reported not using a condom during sexual relations, 70% (n= 36) were people living with human immunodeficiency virus (HIV), and 82% (n= 42) reported a previous history of a sexually transmitted infection. The most frequent route of transmission was sexual, in 74% (n= 38). The distribution of vesiculopus- tular lesions was as follows: 72% (n= 37) on upper limbs, 70% (n=36) on the trunk, and 66% (n= 34) in the anogenital region. Proctitis was present in 13.7% (n=7). The estimated recovery time was 25 days. Conclusions: Mpox virus infection primarily affected young MSM men, with HIV comorbidity. Sexual transmission was predominant, and lesions were located were mostly located on the upper limbs, trunk, and anogenital area. The course of the disease was self-limited, with recovery in approximately 25 days.
