The Omicron variant is the most recent variant of concern (VOC) to emerge and was recognized by the World Health Organization (WHO) on 26 November 2021.

AbstractAlaska has the lowest population density in the United States (US) with a mix of urban centers and isolated rural communities.

AbstractMillions of Norway rats (Rattus norvegicus)inhabit New York City (NYC), presenting the potential for transmission of SARS-CoV-2 from humans to rats and other wildlife.

The results indicated that Rt value and public health and social measures (PHSM)-index of the epidemics were a negative correlation in all cities, except Shenzhen.

The reverse transcription–polymerase chain reaction (RT–PCR) test, rapid antigen assays, and chest computed tomography (CT) scans can help diagnose the Omicron variant.

They were further allocated to the early elimination (EE) and prolonged elimination (PE) groups according to SARS-CoV-2 nucleic acid positivity duration.ResultsCompared to patients with EE, those with PE had increased serum concentrations of interleukin (IL)-5, IL-6, and IL-8; higher neutrophil count and neutrophil-to-lymphocyte ratio (NLR); lower lymphocyte, eosinophil, and red blood cell counts; and lower concentrations of hemoglobin and albumin (ALB).

Furthermore, the PJI-injected GP∆-delta DNA vaccine effectively protected human angiotensin-converting enzyme 2 (hACE2) knock-in mice from delta-variant infection.

This mutation overlaps with a commonly used fluorescent probe for N gene detection in many Emergency Use Authorization (EUA) assays, as this target was originally established by the U.S. Centers for Disease Control and Prevention (CDC) in their EUA test for COVID-19 (2019-nCoV_N1).

We present data about deposits of complete genomic sequences of SARS-CoV-2 in the Global Initiative on Sharing All Influenza Data (GISAID) database made between January 2021 and May 31, 2022.

Among the variants, the glycosylation sites with significant changes in glycan profile were observed at both the N-terminal domain (NTD) and RBD of S protein, with Omicron showing the highest deviation.
