An estimated 884 million people worldwide do not have access to an improved drinking water source, and the microbial quality of these sources is often unknown. In this study, a combined tangential flow, hollow fiber ultrafiltration (UF), and real-time PCR method was applied to large volume (100 L) groundwater (N = 4), surface water (N = 9), and finished (i.e., receiving treatment) drinking water (N = 6) samples for the evaluation of human enteric viruses and bacterial indicators. Human enteric viruses including norovirus GI and GII, adenovirus, and polyomavirus were detected in five different samples including one groundwater, three surface water, and one drinking water sample. Total coliforms and Escherichia coli assessed for each sample before and after UF revealed a lack of correlation between bacterial indicators and the presence of human enteric viruses.

INO-4800 represents a DNA-based vaccine encoding the spike protein of SARS-CoV-2. This phase 2 trial evaluated the immunogenicity and safety of INO-4800 as a primary vaccination series in adults. We conducted a randomized, observer-blind, placebo-controlled phase 2 trial of intradermal injection of INO-4800 in both healthy adults and elderly individuals.

Using a large health insurance database in Japan, we examined the real-world usage of budesonide enteric-coated capsules (BUD) in treating Crohn's disease. We analyzed data from the Japan Medical Data Center claims database for Crohn's disease patients prescribed BUD from April 2016 to March 2021, focusing on prescription status, adverse events (AEs), monitoring tests, and concomitant medications over 2 years following BUD initiation. Patients were categorized into two groups based on BUD usage duration: ≤1 year and >1 year.

This strategy was designed to inhibit mutation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19. This study explores the dynamics of viral evolution under stringent non-pharmaceutical interventions (NPIs) through real-world observations.

Acute gastroenteritis (AG) is a major illness in early childhood. Recent studies suggest a potential association between human bocavirus (HBoV) and AG. HBoV, a non-enveloped virus with a single-strand DNA genome, belongs to the Parvoviridae family.
