SARS-CoV-2 can be transmitted by cats

Researchers in The Netherlands have warned that domestic cats may play a role in the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Study evaluates physical activity and sedentary behavior in relation to OSA risk

Being more physically active and spending fewer hours per day sitting watching TV is linked to a substantially lower risk of developing obstructive sleep apnea (OSA), according to new research published in the European Respiratory Journal

Combination antibody therapies retain potency against SARS-CoV-2 variants, FDA / HHS research

Researchers in the United States have conducted a study showing that while variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can compromise the effectiveness of single therapeutic antibodies at preventing severe coronavirus disease 2019 (COVID-19), many combination antibody products remain potent against the variants.

Scientists seek to block pathogen’s most reliable weapon to cause severe malaria

The parasites that cause severe malaria are well-known for the sinister ways they infect humans, but new research may lead to drugs that could block one of their most reliable weapons: interference with the immune response.

Scientists identify gut microbiota dysbiosis as a potential risk factor for long COVID

A study in Norway has recently highlighted a significant association between gut microbiota alteration and persistent respiratory dysfunction in coronavirus disease 2019 (COVID-19) patients.

Intestinal organoids demonstrate variability in SARS-CoV-2 susceptibility

Three-dimensional organoid structures grown in the lab allow deeper, almost in situ investigation of a biological system, without the use of living animals. In a paper recently uploaded to the preprint server bioRxiv*, organoids generated from human specimens are utilized to investigate the way in which SARS-CoV-2 interacts with the numerous cells of the intestinal epithelium, finding great heterogeneity in the susceptibility of the organoids and the cells within to infection.

Study examines the host and viral factors that drive SARS-CoV-2 evolution

In a new paper recently uploaded to the preprint server bioRxiv*, two clinical isolates of SARS-CoV-2 are monitored by whole genome sequencing as they are passaged through several generations of Vero cells or human-derived primary nasal epithelial cells (PNEC), allowing direct observation of the occurrence of virus enhancing mutations and the way in which host cell factors shape virus evolution.

Study associates feelings of discrimination and low status with long COVID-19 symptoms

A recent study, released as a preprint on the medRxiv* server, examines the correlation of these symptoms with the patient’s socioeconomic status (SES) and perception of social discrimination, along with other social factors. The researchers found that the first two factors are associated strongly with long-term symptoms of COVID-19.

How to run a COVID-19 vaccination campaign: lessons from other infectious outbreaks

A new paper, available on the medRxiv* preprint server, presents lessons learned from the implementation of three adult vaccine programs in low- and middle-income countries (LMICs) in Africa and South America.

COVIDcast API: An open repository of real-time COVID-19 indicators

A new preprint available on the medRxiv* server reports the utility of the COVIDcast API, a database of all COVID-19 indicators that are constantly being updated, dating from April 2020.

Human coronaviruses need organic materials to transfer efficiently between surfaces

This study, published in the journal Viruses, indicated that human coronaviruses do not transfer effectively from contaminated hands to contact surfaces without the presence of any organic material.

Scientists explore susceptibility of different animals to SARS-CoV-2 infection

A team of researchers at the Institute of Infectious Diseases (IFIK) at the University of Bern and the Institute of Virology and Immunology (IVI) has utilized a unique collection of advanced cell culture models of cells lining the airways from various domesticated and wildlife animals. This way, the team can determine which animals are susceptible to SARS-CoV-2 infection.

Reusable N95 masks could offer reduction in waste and cost, study shows

Since the Covid-19 pandemic began last year, face masks and other personal protective equipment have become essential for health care workers. Disposable N95 masks have been in especially high demand to help prevent the spread of SARS-CoV-2, the virus that causes Covid-19.

Potent nasal vaccine protects non-human primates from SARS-CoV-2

A team of US-based scientists has recently demonstrated the efficacy of a live attenuated, recombinant coronavirus disease 2019 (COVID-19) vaccine candidate currently under phase I clinical trial as a single-dose intranasal vaccine.

Structural changes in receptor-binding interface may induce immune fitness of SARS-CoV-2 delta variant

Florida International University researchers have investigated the mutation-induced structural changes in the delta variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that could contribute to its immune evasion abilities.

COVID-19 vaccination remains Australia's best option for a return to normal, say researchers

Researchers in Australia and the United States have advised that the recent decision in Australia to prioritize older vulnerable age groups for vaccination against coronavirus disease 2019 (COVID-19) represents the optimal strategy for reducing deaths caused by the disease.

Next-generation COVID-19 vaccine provides robust immunity against SARS-CoV-2 in mice

Researchers in Canada have developed an adenoviral vector-based vaccine against coronavirus disease 2019 (COVID-19) that induced robust immune protection against the ancestral strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in mice.

IQWiG finds no benefit of high-flow therapy for COPD and type 1 respiratory failure

No benefit of high-flow therapy (HFT) can be derived from the available study data for patients with advanced chronic obstructive pulmonary disease (COPD) or chronic type 1 respiratory failure. It therefore remains unclear whether this form of treatment has advantages over long-term oxygen therapy (LTOT) or non-invasive ventilation (NIV).
