Long COVID in Healthcare Workers from a Pediatric Hospital in Romania: A Cross-Sectional Study of Prevalence, Symptom Burden, and the Role of Vaccination and Reinfection.

Background/

Objectives

Long COVID, characterized by persistent symptoms following SARS-CoV-2 infection, poses a significant occupational health concern among healthcare workers (HCWs). This study aimed to evaluate the prevalence of long COVID, symptom patterns, work-related impact, and vaccination status among healthcare personnel in a Romanian pediatric hospital.

Methods

A cross-sectional study was conducted in 2024 among 903 hospital employees during routine occupational health assessments. Data were collected using structured questionnaires and medical records, focusing on previous SARS-CoV-2 infection, vaccination status, persistent symptoms, and functional impact.

Results

Long COVID was identified in 28.6% of participants, with excessive fatigue (53.5%), musculoskeletal pain, respiratory difficulties, and cognitive complaints being the most common symptoms. Staff with chronic comorbidities or increased exposure risk had significantly higher rates of functional impairment. Fewer reinfections were reported among vaccinated individuals; however, vaccination was not significantly associated with the presence of long COVID symptoms. Older age and comorbidities were correlated with higher risk.

Conclusions

The findings underline the need for long-term occupational health strategies and individualized support programs for HCWs affected by long COVID, particularly in high-risk groups.
