Study shows likely SARS-CoV-2 transmission between different rooms of a quarantine hotel SARSCoV2 Taiwan Coronavirus Disease COVID quarantine CDC_NCEZID
By Dr. Liji Thomas, MDNov 6 2022Reviewed by Emily Henderson, B.Sc. A unique experiment using tracer gas was recently conducted at a Taiwan hotel converted to a quarantine center for people exposed to the severe acute respiratory syndrome coronavirus 2 but showed no signs of infection. The goal was to identify the routes of the spread of the virus, which had caused a small outbreak in the hotel.
Aerosol transmission has been recognized as a potential transmission route by the World Health Organization and the US Centers for Disease Control and Prevention when people are crowded together indoors or when indoor ventilation is inadequate for the number of people and the space. As might have been expected, the first of many outbreaks occurred in December 2021 in one such hotel, involving eight travelers infected with the Delta variant. At least 15 outbreaks followed, of which one was reported on December 29, 2021. This affected three people staying in different rooms on different floors, but all became infected during the quarantine period.
Related StoriesThe first case came from China, stayed in room 611, and remained asymptomatic but tested positive on day 14 of quarantine . The next day all hotel residents on these two floors were tested for the virus. All three infected patients had the same subclade of the Omicron lineage, showing the same three unique single nucleotide polymorphisms. There were two nucleotides different between the strains from the three cases.

The lower airways microbiota and antimicrobial peptides indicate dysbiosis in sarcoidosis - MicrobiomeBackground The role of the pulmonary microbiome in sarcoidosis is unknown. The objectives of this study were the following: (1) examine whether the pulmonary fungal and bacterial microbiota differed in patients with sarcoidosis compared with controls; (2) examine whether there was an association between the microbiota and levels of the antimicrobial peptides (AMPs) in protected bronchoalveolar lavage (PBAL). Methods Thirty-five sarcoidosis patients and 35 healthy controls underwent bronchoscopy and were sampled with oral wash (OW), protected BAL (PBAL), and left protected sterile brushes (LPSB). The fungal ITS1 region and the V3V4 region of the bacterial 16S rRNA gene were sequenced. Bioinformatic analyses were performed with QIIME 2. The AMPs secretory leucocyte protease inhibitor (SLPI) and human beta defensins 1 and 2 (hBD-1 and hBD-2), were measured in PBAL by enzyme-linked immunosorbent assay (ELISA). Results Aspergillus dominated the PBAL samples in sarcoidosis. Differences in bacterial taxonomy were minor. There was no significant difference in fungal alpha diversity between sarcoidosis and controls, but the bacterial alpha diversity in sarcoidosis was significantly lower in OW (p=0.047) and PBAL (p=0.03) compared with controls. The beta diversity for sarcoidosis compared with controls differed for both fungi and bacteria. AMP levels were significantly lower in sarcoidosis compared to controls (SLPI and hBD-1: p | 0.01). No significant correlations were found between alpha diversity and AMPs. Conclusions The pulmonary fungal and bacterial microbiota in sarcoidosis differed from in controls. Lower antimicrobial peptides levels were seen in sarcoidosis, indicating an interaction between the microbiota and the innate immune system. Whether this dysbiosis represents a pathogenic mechanism in sarcoidosis needs to be confirmed in experimental studies. Video Abstract
