Objectives: The development of a rapid diagnostic test for viable SARS-CoV-2 is important for infection control. Real-time RT-PCR assays detect non-viable virus, and cell culture differentiates viable virus but it takes several weeks and is labour-intensive. Subgenomic RNAs may reflect replication-competent virus.

However, until now, the duration and clinical implications of antibody-mediated nature immunity in Koreans have remained unknown. Therefore, we examined NAbs levels and clinical characteristics in recovered coronavirus disease 2019 (COVID-19) patients.

- - The study explored the effectiveness of a UV LED robot for disinfecting rooms of COVID-19 patients by checking for viral RNA on surfaces before and after treatment.
- - A total of 216 samples were collected from 17 patient rooms, revealing that 18.5% had detectable SARS-CoV-2 RNA after discharge, with significant differences between ICU and community isolation rooms.
- - While no viable virus was found after UV treatment, the robot worked well in large ICU settings but had less effectiveness in smaller community treatment rooms, indicating that space is crucial for optimal disinfection.
Wuhan, a megacity in central China, suffers from frequent aerosol pollution and is accompanied by meteorological factors at both synoptic and local scales. Partly due to the lack of appropriate observations of planetary boundary layer (PBL), the associations between synoptic conditions, PBL, and pollution there are not yet fully understood. Thus, systematic analyses were conducted using the fine-resolution soundings, surface meteorological measurements, and aerosol observations in Wuhan during summer for the period 2013-2016, in combination with T-mode principal component analysis and simulations of backward trajectory.

Methods: The study cohort consisted of 88 patients with a minimum of two years of follow-up. Patient satisfaction was evaluated with a questionnaire that assessed (1) overall satisfaction, (2) pain relief, (3) daily living functions, and (4) cosmesis.
