The U.K. said its BA.2.86 case was tested at a London hospital, but that it was currently not possible "to assess comparative severity by variant" based on their data. Do COVID tests work for new COVID variants? They seem to work, although that may change if one of the strains beco...
Severity of symptoms To assess whether there are differences in symptom severity between BA.2 and BA.1 independent of vaccination history we took a subset of swab-positive individuals with sequence-confirmed BA.2 or BA.1 who had received second or third vaccines at least two weeks before their...
We also found that women, and individuals infected by the original (first) virus variant, had a higher risk of post-COVID complaints. There was no strong or clear social gradient in the prevalence of the post-covid. Last, we found that when accounting for virus type, vaccination was not...
Previous experiences with other variants lead us to believe that only time and surveillance will give us more information on transmissibility, vaccine efficacy and severity of the disease caused by this new variant. Whether Omicron will turn out to be an ‘a storm in a teacup’ or a lethal ...
1c) were also found when separating the COVID-19 samples by severity (Additional file 2: Figure S1B,C). Both, severe and mild COVID-19 in comparison to controls shared neutrophil-specific CD177 and HP expression among the most upregulated DEGs, as well as lymphocyte-associated genes such...
"In the worst-case scenario, a more virulent and highly transmissible variant emerges. Against this new threat, people's protection against severe disease and death, either from prior vaccination or infection, will wane rapidly." The WHO chief put forward outright his recommendations for countries ...
There is an urgent need to collect more age-specific data to assess the severity of illness related to new variants as well as potential longer-term effects, said the AAP. "It is important to recognize there are immediate effects of the pandemic on children's health, but importantly we need...
The transmissibility and severity of SARS-CoV-2 likely increased due to some devastating mutations, such as the mutation in D614G amino acid. These evolved mutations may result from natural selection, and the steady increase of the G614 variant at regional stages could designate a fitness gain ...

Long COVID (LC) occurs after at least 10% of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, yet its etiology remains poorly understood. We used ‘omic” assays and serology to deeply characterize the global and SARS-CoV-2-specific immunity in the blood of individuals...
