COMPARISON OF BACTERIAL FILTRATION EFFICIENCY VS. PARTICLE FILTRATION EFFICIENCY TO ASSESS THE PERFORMANCE OF NON-MEDICAL FACE MASKS

Comparison of bacterial filtration efficiency vs. particle filtration efficiency to assess the performance of non-medical face masks

Abstract As a result of the current COVID-19 pandemic, the use of facemasks has become commonplace.The performance of medical facemasks is assessed using Bacterial Filtration Efficiency (BFE) tests.However, as BFE tests, require specific expertise and equipment and are time-consuming, the performance of non-medical facemasks is assessed with non-bi

Genomic surveillance of Neisseria meningitidis serogroup B invasive strains: Diversity of vaccine antigen types, Brazil, 2016-2018.

BackgroundNeisseria meningitidis serogroup B remains a prominent cause of invasive meningococcal disease (IMD) in Brazil.Because two novel protein-based vaccines against serogroup B are available, the main purpose of this study was to provide data on the diversity and distribution of meningococcal vaccine antigen types circulating in Brazil.Methodo
