Parts of the F gene from 16 mumps viruses derived from vaccines and clinical isolates were amplified using the polymerase chain reaction and their nucleotide sequences were determined. Over a region of 111 nucleotides, eight regions of variability were detected with a maximum of six (5.4%) changes occurring between any two virus strains. The Jeryl Lynn and Urabe vaccine strains were clearly different from each other and from wild virus isolated from cases of non-vaccine-associated mumps. In contrast, viruses isolated from the cerebrospinal fluid and throat in cases of meningitis and parotitis following vaccination with the Urabe strain were identical to this strain. We conclude that the vaccine was the source of these infections.

Objectives: Mumps (infectious parotitis) is an acute respiratory illness caused by the mumps virus in humans. While numerous studies have explored the impact of climate variability on mumps incidence in specific cities or regions, few have analyzed nationwide associations across multiple locations. This study aims to systematically assess the short-term effects of meteorological factors on mumps incidence across Japan over a 15-year period.

Background and objective Viral infections caused by cytomegalovirus, lymphocytic choriomeningitis virus, varicella-zoster virus, herpes simplex type 1 and type 2, rubella, measles, rubeola, HIV, West Nile virus, Lassa virus, and mumps are known to be associated with hearing loss. There have been reports of inner ear involvement in coronavirus disease 2019 (COVID-19) patients but the extent and variations in cochlear involvement of symptomatic and asymptomatic patients has not been adequately described. This study aimed to evaluate the hearing status among symptomatic and asymptomatic COVID-19 patients to address the prospects for routine screening for hearing loss in COVID-19 patients.

The mpox virus (MPXV) came to global attention with the 2022 global outbreak. Current vaccination and post-exposure prophylaxis against MPXV consists of live vaccinia whole virus-based vaccines including ACAM2000®, JYNNEOS™, and LC16m8 originally developed against smallpox. Here, we analyzed 152 vaccinia-derived peptides we identified by mass spectrometry for homology with MPXV-1 and MPXV-2 sequences to evaluate their potential relevance to MPXV-specific immunity.

Description: The aim of this American Gastroenterological Association (AGA) Clinical Practice Update (CPU) is to provide best practice advice (BPA) statements for gastroenterologists and other health care providers who provide care to patients with inflammatory bowel disease (IBD). The focus is on IBD-specific screenings (excluding colorectal cancer screening, which is discussed separately) and vaccinations. We provide guidance to ensure that patients are up to date with the disease-specific cancer screenings, vaccinations, as well as advice for mental health and general wellbeing.
