T-cell immune response in previously infected and vaccinated individuals effective against SARS-CoV-2 Omicron variant

New findings illustrate that despite the continuous pattern of the ongoing evolution of SARS-CoV-2, it has not resulted in any significant accumulation of CD8+ T-cell escape mutations.

Receptor binding of SARS-CoV-2 Omicron variant compared to other variants

Researchers compared the binding of the new SARS-CoV-2 VOC Omicron’s RBD and ACE2 receptor with the original Wuhan SARS-CoV-2 strain and other VOCs such as Beta and Delta.

Impact of exogenous antibody therapy by convalescent plasma against SARS-CoV-2

Researches have been investigating the possibility of using convalescent plasma to help patients recover from COVID-19.

Monoclonal antibody activity against SARS-CoV-2 Omicron variant

Scientists from Germany have recently pointed out that the third booster dose of mRNA-based COVID-19 vaccine is highly effective in neutralizing the omicron variant of SARS-CoV-2.

Effectiveness of inactivating SARS-CoV-2 by spraying disinfectant in the form of Dry Fog

A new study investigates the use of aerosolized hypochlorous acid solution and hydrogen peroxide solution for inactivation of SARS-CoV-2 and influenza A virus adhering to an environmental surface.

Risk of Guillain-Barré syndrome decreases after COVID-19 vaccination

A new study suggests that low GBS incidence in vaccinated patients compared to non-vaccinated people should encourage the active propagation of vaccination against SARS-CoV-2.

Structure of human receptor and Omicron variant

Researchers studied the complex structure of the receptor-binding domain of the omicron variant with the human host receptor angiotensin-converting enzyme 2.

Eating before saliva collection may interfere with detection of SARS-CoV-2

A new study, published on the medRxiv* preprint server, has aimed to determine if children's diet impacts the detection of SARS-CoV-2 virus in saliva. Scientists performed diagnostic tests to detect this virus using real-time self-collected specimens provided by five healthy children. The samples were collected before and after eating selected foods. The specific time of collection of samples after eating were 0 minutes, 20 minutes, and 60 minutes after eating.

How fast has the Omicron strain been spreading in South Africa?

Scientists have shown the exponential growth of the Omicron strain found in Gauteng. They reported the doubling time of this strain to be equal to 3.38 days by analyzing its growth from November 8 to December 5, 2021. Based on the mutation accumulation profile, researchers revealed that this strain began to diverge between October 28 and November 5, 2021.

Climate change will affect bats hosting future coronaviruses, scientists predict

A new study led by David T. S. Hayman of Massey University in New Zealand details the creation of an ecological modeling pipeline to identify bat biodiversity data and patterns on bat distribution based on climate and landscape relationships.

Frequent cognitive impairments after 4-month follow-up in ICU COVID-19 patients

Results from a recent observational study published in the Journal Of The Neurological Sciences found that after a 4-month follow-up, ICU patients with severe COVID-19 illness were more likely to have mild cognitive impairment with features related to a diffuse encephalopathy than patients with mild infection who do not need a ventilator. Additionally, ICU patients experienced more significant impairment in executive function. All neurological deficits involve the peripheral nervous system.

Thrombosis may increase mortality risk in hospitalized COVID-19 patients

A team of US-based scientists has recently explored various risk factors associated with the poor prognosis of coronavirus disease 2019 (COVID-19). They have identified thrombosis-related risk factors as a major predictor of in-hospital COVID-19 related mortality. The study is currently available on the medRxiv* preprint server while awaiting peer review.
