SARS-CoV 2 Omicron prevalent in vaccine breakthrough cases in Bahia, Brazil

In a recent study posted to the medRxiv* pre-print server, researchers performed genomic monitoring to estimate the magnitude and range of the different severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern (VOCs) in SARS-CoV-2 reinfection cases among fully vaccinated individuals in Salvador, Bahia, Brazil.

Circulating miR-155 may predict chances of survival in hospitalized COVID-19 patients

Scientists from Israel have recently estimated the levels of circulating microRNAs (miRNAs) in hospitalized coronavirus disease 2019 (COVID-19) patients with the aim of identifying prognostic biomarkers for disease severity. They have identified miR-155, an important regulatory molecule in the immune system, as a potential biomarker to predict COVID-19 severity and mortality.
