Article Abstract
Since the start of SARS-CoV-2 pandemic, children aged ≤ 12 years have always been defined as underrepresented in terms of SARS-CoV-2 infections' frequency and severity. By correlating SARS-CoV-2 transmission dynamics with clinical and virological features in 612 SARS-CoV-2 positive patients aged ≤ 12 years, we demonstrated a sizeable circulation of different SARS-CoV-2 lineages over the four pandemic waves in paediatric population, sustained by local transmission chains. Age < 5 years, highest viral load, gamma and delta clades positively influence this local transmission. No correlations between COVID-19 manifestations and lineages or transmission chains are seen, except for a negative correlation between B.1.1.7 and hospitalization.

Repurposing disulfiram: An innovative inhibitory approach against a broad spectrum of viruses.

Disulfiram (DSF), an FDA-approved therapeutic agent for alcohol dependence, has recently attracted considerable interest due to its broad-spectrum inhibitory effects against various viruses. Increasing evidence suggests that DSF can inhibit viral replication through two major mechanisms: the inhibition of viral protein catalytic activity and the ejection of Zn from viral proteins. This review comprehensively summarized the molecular mechanisms underlying DSF's antiviral activity against viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), hepatitis C virus (HCV), influenza virus, human immunodeficiency virus (HIV), and Kaposi sarcoma-associated herpes virus (KSHV), with a particular focus on its dual targeting of Cys residues and Zn coordination sites.

Introduction: Hajj is the largest annual mass gathering in the world, attracting more than 2 million pilgrims from 184 countries. Adverse climatic conditions and close proximity of pilgrims during Hajj rituals create a facilitating environment for the transmission of infectious agents, including multi-drug resistant organisms. Although, several individual reports have been published on specific type of infections, there is a paucity of published work reflecting the overall picture of the prevalence of pathogenic infections during Hajj.

Tilorone, a 9-fluorenone scaffold-based molecule, is a known broad-spectrum antiviral with an IC of 180 nM against SARS-CoV-2, but its mechanism is not known. In the present study, we found it to have weak activity against PLpro (IC = 30.7 ± 7.

Background: Remote services (in which the patient and staff member are not physically colocated) and digital services (in which a patient encounter is digitally mediated in some way) were introduced extensively when the COVID-19 pandemic began in 2020. We undertook a longitudinal qualitative study of the introduction, embedding, evolution and abandonment of remote and digital innovations in United Kingdom general practice. This synoptic paper summarises study design, methods, key findings, outputs and impacts to date.

BACKGROUND The SENTINEL influenza surveillance system has been used in Poland since 2004, incorporating both epidemiological and virological monitoring of influenza viruses. SENTINEL works in cooperation with general practitioners, 16 Voivodship Sanitary Epidemiological Stations (VSES), and the National Influenza Centre (NIC). NON-SENTINEL samples are collected from places that do not participate in the SENTINEL program.
