Background: The rapid spread of COVID-19 worldwide has impo-sed the need to identify a test that quickly recognizes affected subjects, both symptomatic and asymptomatic. The most reliable option has been proven to be the RT-PCR, which allows to detect virus RNA on a specimen from a high viral load site, such as nasopharynx. Nasopha-ryngeal sample collection is possible by means of a nasopharyngeal swab (NPS) and is a practical and relatively non-invasive technique, but rather bothersome for the recipient.
Aim: The aim of the present study is to evaluate the discomfort evoked during NPS.
Materials And Methods: We surveyed 429 patients receiving NPS before hospitalization or other procedures non related to COVID-19. For each one we noted the discomfort level felt during the swab using a 11-point numeric rating scale (NRS) for pain and the total time needed for the procedure to be taken. Sex, age, smoking status and positive history of previous swab have been taken into account.
Results: We found that, among the variables, sex had a statistically significant impact on the perceived discomfort of nasal swab, with females experiencing slightly more discomfort.
Conclusions: NPS is largely a none-to-minimum discomfort in-ducing procedure. The differences in perceived discomfort could be explained based on anatomical features, and should remark the need for a tailored and anatomy-oriented approach in each patient.

Hypoxemic Human Metapneumovirus Pneumonia in a Young Immunocompetent Man in the First Autumn After the Reclassification of Coronavirus Disease.

Although human metapneumovirus(hMPV) infection can induce severe symptoms in older adults or immunocompromised patients, it usually causes mild symptoms in young immunocompetent adults. The prevalence of hMPV infectious disease is highest during the late winter and early summer. We report a hypoxemic case of hMPV infection in a young immunocompetent man that occurred in the first autumn after the reclassification of coronavirus disease (COVID-19) from Class 2 to Class 5.

Background: We aimed to evaluate the efficacy of integrating the Varia5 multiplex assay (qPCR) and whole genome sequencing (WGS) for monitoring SARS-CoV-2, focusing on their overall performance in identifying various virus variants.
Methods: This study included 140 naso-pharyngeal swab samples from individuals with suspected COVID-19. We utilized our self-developed Varia5 multiplex assay, which targets five viral genes linked to COVID-19 mutations, in conjunction with comprehensive genomic analysis performed through whole genome sequencing (WGS) using the Oxford Nanopore system.

Human seasonal coronaviruses (hCoVs) are a group of viruses that affect the upper respiratory tract. While seasonal patterns and the annual variability of predominant hCoV species are well-documented, their genetic and species diversity in St. Petersburg and across Russia remains largely unexplored.

Background: Respiratory viral infections are a major public health challenge and the most diagnosed medical condition, particularly for individuals living in close proximity, like military personnel. We compared the sensitivity and specificity of the Biomeme Franklin and Truelab RT-PCR thermocyclers to determine which platform is more sensitive and specific at detecting SARS-CoV-2 and influenza A and B viruses.
Methodology: RNA extracted from nasopharyngeal swabs of infected and uninfected individuals was tested on the Biomeme Franklin at Lackland and the Truelab at Wright Patterson Air Force bases.
A Rare Pediatric Case of COVID-19-Associated Guillain-Barré Syndrome With Multiple Cranial Neuropathies and Without Pulmonary Symptoms.

Department of Microbiology, Fırat University School of Medicine, Elazig, TUR.
Coronavirus disease (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that primarily affects the respiratory system but can also lead to neurological complications such as Guillain-Barré syndrome (GBS). This case report describes an eight-year-old boy with COVID-19-associated GBS involving multiple cranial nerves (third, seventh, and ninth) without pulmonary symptoms. The patient initially presented with flu-like symptoms along with right facial paralysis, which progressed to bilateral facial paralysis, limb weakness, and sensory loss.
