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.

Omicron evades immunity more than other SARS-CoV-2 variants

Researchers find that the SARS-CoV-2 Omicron variant shows a much more extensive escape from vaccine-elicited immunity.

Surveillance key to dealing with novel SARS-CoV-2 variants of concern

Researchers critically evaluate the performance of public health surveillance systems in detecting COVID-19 community outbreaks in Australia.

The evolution of SARS-CoV-2 variants during slow and fast epidemics

Researchers discuss an analytical framework to investigate the contribution of the transmissibility advantage SARS-CoV-2 variants.

Study finds prior infection boosts antibody responses after a single COVID-19 vaccination

In a recent study, researchers evaluated the antibody response in previously infected individuals after a single dose of several COVID-19 vaccines.

Self-collected samples on par with gold standard for detection of SARS-CoV-2

Researchers directly compare the diagnostic sensitivity of self-collected samples.

Nanotrap particles can improve current sequencing workflows of SARS-CoV-2

New research uses an affinity-based magnetic hydrogel particle enrichment technology (Nanotrap particle enrichment technology) that can concentrate viral particles, leading to improved detection of many viral agents including SARS-CoV-2

Severity of SARS-CoV-2 compared to other human coronaviruses in children

Researchers observed that symptom presentation of SARS-CoV-2 infections at the community level was very similar to that of endemic human coronavirus infections.

Dynamics and relative transmission rates of SARS-CoV-2 variants in the US

Findings of a new study reveal that the transmission dynamics of SARS-CoV-2 variants could help tackle local and regional epidemics.

Timing of exposure critical for SARS-CoV-2 transmission according to animal study

In a new study, the researchers assessed the spread of SARS-CoV-2 in golden Syrian hamsters to get a perspective on spatio-temporal conditions impacting the transmission efficiency of SARS-CoV-2 through the air.

SARS-CoV-2 patients exhibit high specialized pro-resolving molecule serum levels

In a new study, researchers compared the serum levels of bioactive lipids in a cohort of 50 in-patients who had confirmed symptomatic SARS-CoV-2 infection with that of a control group.

Vaccinated seropositive individuals are able to induce high anti-spike SIgA responses

Results of a new study show that the induction of anti-SARSCoV-2 spike saliva SIgA antibodies after vaccination is independent of the gender or type of vaccine received.
