Resumen
This study aimed to assess the prevalence, predictive factors, and post-COVID-19 symptoms of SARS-CoV-2 infection among Mobile Emergency Medical Service (SAMU) professionals in Mato Grosso do Sul, Brazil. A cross-sectional design was used, based on primary quantitative data. SARS-CoV-2 infection was defined based on self-reported information indicating at least one positive real-time reverse transcription quantitative polymerase chain reaction (RT-qPCR) or rapid antigen/protein test result. Among 197 participants (mean age 42.4 years), 57.0% were male and 72.0% had higher education. Most were overweight/obese (74.0%), and 22.0% reported previous comorbidities. Nursing technicians represented 31.0% of the sample. Although 87.0% received training on personal protective equipment (PPE) use, 40.0% admitted to not using it at some point. A high prevalence of SARS-CoV-2 infection was found (55.3%; 95.0% CI: 48.30-68.20). Multivariate analysis showed that infection was associated with prior contact with infected individuals, fewer than two training sessions, and lack of training on proper PPE use. Additionally, 51.2% reported persistent symptoms lasting up to five months after infection. These findings indicate that SAMU professionals face a high risk of SARS-CoV-2 exposure. Proper PPE training is essential to reduce infection risk in healthcare workers.
