Research finds potential overuse of antibiotics in patients with severe SARS-CoV-2 pneumonia

Only 21 percent of patients with severe pneumonia caused by SARS-CoV-2 (the virus that causes COVID-19) have a documented bacterial superinfection at the time of intubation, resulting in potential overuse of antibiotics, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

Moderna COVID-19 vaccine safe and efficacious in adolescents according to a new study

The safety, immunogenicity, and efficacy of the vaccines in adolescents are largely unknown. Now, a new study published in the New England Journal of Medicine evaluates the safety and efficacy of the mRNA-1273 vaccine in adolescents (12-17 years of age).

Ten-fold reduced risk of workplace SARS-CoV-2 infection in seropositive essential workers

A reassuring new study supports the opening of workplaces to seropositive workers in view of the extremely low risk of reinfection observed in this cohort.

UC San Diego’s wastewater surveillance system enables early detection of most COVID-19 cases

People infected with SARS-CoV-2, the virus that causes COVID-19, are known to shed it in their stool, even if they aren't experiencing any symptoms.

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.

Emerging biosensing technologies could revolutionize the diagnosis of neonatal sepsis

Sepsis in newborn infants can be fatal. Early diagnosis is thus key to effectively manage the infection. Conventional diagnostic methods are, however, time-consuming.

Researchers employ artificial intelligence models for image-based detection of COVID-19

Medical imaging has long been a vital tool for the diagnosis and prognostic assessments of many diseases. In recent years, the use of artificial intelligence models has been used in conjunction with this imaging to augment their diagnostic capabilities.

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.

Research shows how SARS-CoV-2 variants are evolving towards increased furin cleavage efficiency

The spike protein comprises of two subunits: S1 subunit having the receptor-binding domain (RBD) that helps it to bind to the angiotensin-converting enzyme 2 (ACE2), which is present on the cell surface of the host, and the S2 subunit that helps in the fusion of the cellular membrane and the viral membrane.

Pfizer/BioNTech COVID-19 vaccine offers decreased protection six months after second dose, suggests Israeli study

A recent study published on the preprint server medRxiv* determines whether the time elapsed since the second dose of the BNT162b2 vaccine is associated with an increased risk of breakthrough SARS-CoV-2 infection.

SARS-CoV-2 Beta variant associated with more critical and fatal disease than Alpha, suggests Qatar study

A new study traces the degree to which the Beta variant of this virus is associated with severe, critical or fatal disease, using a case-control model.

Double vaccinated three times less likely to test positive for COVID-19 than unvaccinated, says study

In new research, scientists at Imperial College London report that double vaccinated individuals could be three times less likely than unvaccinated people to test positive for SARS-CoV-2 infection.

6 Aug 2021

Using two different CRISPR enzymes to develop a faster and easier COVID-19 diagnostic test

Frequent, rapid testing for COVID-19 is critical to controlling the spread of outbreaks, especially as new, more transmissible variants emerge.

5 Aug 2021

A correlation study between time-from-vaccine and SARS-CoV-2 breakthrough infections

A new retrospective study compares the incidence rates of breakthrough infections between different time points at which individuals were vaccinated.

Diagnosis of viral infections using micro and nanoscale technologies

In a recent study, the authors provide a review on both micro- and nanoscale technologies that advanced the diagnosis of viral diseases.

3 Aug 2021

Unvaccinated and vaccinated have similar viral load in communities high in SARS-CoV-2 delta

The findings reveal that vaccinated and unvaccinated individuals exhibit similar viral loads following delta infection and that vaccine breakthrough cases have the potential to transmit infection to others. The study is currently available on the medRxiv* preprint server.

3 Aug 2021

National Qatari study shows vaccination reduces risk of spreading SARS-CoV-2 infection

A team of scientists from Qatar and the United States has recently studied the viral transmission potential of individuals with primary severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, reinfection, or vaccine breakthrough infection.
