RESUMO

Throughout the current COVID-19 pandemic, preventing nosocomial COVID-19 outbreaks has been a significant challenge for hospitals. It is essential to understand the ways in which SARS-CoV-2 spreads in healthcare settings to apply proper infection prevention and control (IPC) measures. The objectives of this study are to report on the hospital's response to a COVID-19 cluster and the transmission dynamics in a hospital ward of Geriatrics, Rehabilitation and Long term care. The study will focus specifically on how insufficient air replacement and directional airflow in indoor settings may have contributed to the transmission of the virus.

RESUMO

Background: In 2016, 362 753 migrants reached Europe by sea. Most of migrants come from high tuberculosis (TB) burden countries and travel in conditions that increase the risk for communicable diseases. The goal of WHO End TB Strategy is to end global epidemic by 2035. Management of latent TB infection (LTBI) in low TB incidence countries is thus essential. Nevertheless, a lack of uniformity in policies and procedures for LTBI screening in Europe is perceived. The aim of this study was to estimate the LTBI prevalence in migrants by Mediterranean Sea. Methods: A cross-sectional study was conducted, involving 1038 migrants. Since a gold standard method is not available, LTBI prevalence was assessed in four alternative scenarios with different thresholds and diagnostic tools: (i) TST ≥ 5 mm; (ii) TST ≥ 10 mm; (iii) TST ≥ 5 mm plus IGRA; and (iv) TST ≥ 10 mm plus IGRA. TST = tuberculin skin test; IGRA = interferon-gamma release assay. Results: The four scenarios returned the following prevalence: (i) TST ≥ 5 mm: 40%; (ii) TST ≥ 10 mm: 33%; (iii) TST ≥ 5 mm plus IGRA: 27%; and (iv) TST ≥ 10 mm plus IGRA: 25%. Moreover, a positive association was found between the proportion of IGRA positive patients and the size of TST induration site. No patient who reported TST ≥ 18 mm tested IGRA negative. Conclusions: Prevalence varied substantially in the investigated scenarios. Significant differences were noted according with the nationality of migrants, probably attributable to different Bacillus Calmette-Guérin vaccination coverage rates in the countries of origin or different exposition to non-tuberculous mycobacteria infection. Data about the nationality can suggest the need of a tailored approach according to migrants' area of origin.
