- Ultraviolet radiation (UV) is divided into three bands (UVA, UVB, UVC) and UVC has strong antimicrobial properties, making it useful for disinfection of surfaces, water, and air.
- The study analyzed articles from Scopus published until April 2023, focusing on the application of ultraviolet germicidal irradiation (UVGI) in disinfecting air and surfaces, considering variables like publication year, sources, and author nationality.
- Results showed that since the 1930s, over 287,000 articles have been published on UV, with significant research on UVGI for bacteria, fungi, and air/surface disinfection, and emerging applications for spacecraft missions to maintain safe environments.
Background And Aim Of The Work: Coronavirus Disease 2019 (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), is a global public health emergency. The aim of this study was to investigate cases characteristics and Real Time RT PCR cycle threshold (Ct) values distribution of COVID-19 in an Italian Northern area during three periods: first period, February-May 2020; second period, June-August 2020; third period, September 2020-February 2021.
Methods: Real Time RT PCR was used to detect SARS-CoV-2 in respiratory samples (oro/nasopharyngeal swabs).
Aim of the study was to investigate the differences in Ct values in nasopharingeal swabs collected in three SARS-CoV-2 epidemic periods: first one from February 23 to March 25 (14 days from lockdown started on March 11); the second one from March 26 to May 18 (14 days from the end of strict lockdown on May 4) and the third one from May 19 until June 15. Viral RNA was detected in nasopharyngeal swabs obtained both from inpatients and outpatients. COVID-19 infection was confirmed according to the Ct values for N1 and N2 genes ascertained by Real-Time RT-PCR assay as described by the CDC.

Children with chronic medical conditions and healthy children may experience severe or fatal complications. Aim of the study was to estimate the influenza vaccine effectiveness (VE) in a cohort of outpatient children.
