Risk factors for hospitalization among HIV patients infected with SARS-CoV-2

The hospitalization of PWH with COVID-19 is related to host factors such as older age and co-morbidities, rather than due to traditional metrics of HIV.

Breakthrough SARS-CoV-2 infections in patients with systemic rheumatic diseases

A recent study discusses the clinical characteristics and outcomes of patients with SARDs who were previously vaccinated against SARS-CoV-2.

Fine aerosols generated during talking, singing may play a major role in SARS-CoV-2 transmission

The coronavirus disease 2019 (COVID-19) has been thought to spread primarily when an infected person coughs or sneezes, but little is known about its transmissibility through activities such as breathing, talking, and singing.

In Australia, high vaccine hesitancy among most vulnerable to COVID-19

World Health Organization (WHO) guidelines indicate the optimal timing of vaccination among specific groups based on the probability of infection and transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), e.g., health care workers providing direct care or acute disease and death (e.g., older people, organ transplant recipients).

A new promising target for broad-spectrum therapeutics against coronaviruses

A recent study by Canadian and US researchers demonstrates how frameshift signals of coronaviruses represent a viable target for developing novel therapeutics with broad-spectrum activity – not only against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but also other constituents of the coronavirus family. The study is currently available on the bioRxiv* preprint server while it undergoes peer review.

COVID-19 vaccines offer better protection than natural immunity alone

Now, the U.S. Centers for Disease Control and Prevention (CDC) reports that among people who were previously infected with SARS-CoV-2, those who were still unvaccinated are more likely to be reinfected than those fully vaccinated after prior infection.

Plant-based virus-like particle vaccine induces durable immune response against SARS-CoV-2 variants

Scientists from Germany and Belgium have recently described the immunogenicity of a plant-based virus-like particle vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The vaccine induces robust antibody and T cell responses for at least 6 months. Moreover, the vaccine demonstrates potent neutralizing efficacy against the B.1.1.7, B.1.351, and P1 variants of SARS-CoV-2.

Both mRNA vaccines protect against symptomatic disease with SARS-CoV-2 Delta variant

A new study demonstrates that the two mRNA vaccines have widely varying efficacies against the SARS-CoV-2 Delta variant.

Green spaces, especially forest, reduce COVID-19 incidence, study says

An intriguing new study reveals that the closer you are to green spaces, especially forests, the less likely you are to be infected with SARS-CoV-2.

Study shows efficacy of gamma irradiation of SARS-CoV-2 vaccine candidate in mouse model

A new study reports a more rapid method of viral inactivation in an effort to increase the appeal of inactivated viral vaccines against the COVID-19 pandemic.

High alcohol consumption increases risk of SARS-CoV-2 infection, finds US student study

A new study finds that heavy alcohol drinking is associated with an increase in the number of COVID-19 cases among American college students.

Natural vs. vaccine-induced COVID-19 immunity

A new paper discusses the protection offered by immunity against COVID-19 following vaccination as compared to natural infection.

Study explores ‘brain fog’ following COVID-19

A recent survey conducted in the United Kingdom revealed that approximately one in every five experiences prolonged coronavirus disease 2019 (COVID-19) symptoms five weeks post-infection. Also, one in seven people reported persistent symptoms even after twelve weeks.

Cardioprotective role of HIF1α in COVID-19 patients

The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which first emerged in Wuhan, China, in late December 2019, has quickly become the most urgent issue facing scientists worldwide. It has been reported that the respiratory infection causes cardiac dysfunction in 25-55% patients, including hospitalized patients and non-critical patients.

SARS-CoV-2 Iota variant increases mortality risk among older adults

The findings reveal that the variant has considerably higher transmissibility and immune escape potential than previously circulating variants and that it can increase the infection fatality rate by 62% - 82% among older adults. The study is currently available on the medRxiv* preprint server.

SARS-CoV-2 variants and their ability to infect mice

A new study published on the bioRxiv* preprint server has conducted in silico studies along with in vitro, in vivo, and in situ observations and indicated the mouse adaptation of SARS-CoV-2.

Evaluation of COVID-19 risk among international travelers in the UK for safety purposes

A high risk of transmission of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent of the coronavirus disease 2019 (COVID-19) pandemic, is associated with international travel.

New protocol for the study of SARS-CoV-2's medium and long-term outcomes

The clinical symptoms of the severe COVID-19 have been well described. In addition, scientists have defined the post-acute COVID-19 as the development of sequelae or persistence of symptoms several weeks after the onset of COVID-19 symptoms. In some cases, the symptoms persist for around 3-4 weeks, and in other cases of chronic COVID-19, symptoms may persist beyond 12 weeks from the onset of symptoms.

Study shows impaired SARS-CoV-2 mRNA vaccine antibody response in individuals with chronic conditions

A recent study in Colorado used real-world data to evaluate if individuals with chronic conditions have reduced antibody response to COVID-19 mRNA vaccines. The study investigated whether some medical conditions may impact antibody response to the mRNA vaccines.

Controlling the spread of SARS-CoV-2 at a large public university

Researchers from the U.S. recently reported a multimodal "SHIELD: Target, Test, and Tell" program that helped mitigate the transmission of SARS-CoV-2 at a large public university. The program also prevented community transmission and helped the continuation of in-person classes during the pandemic. This study is available on the medRxiv* preprint server.
