Predictability of single symptom screening for pediatric SARS-CoV-2 infections

A new study on the preprint server medRxiv* discusses the predictive value of single symptom-based screening to confirm pediatric SARS-CoV-2 cases.

Higher SARS-CoV-2 Delta variant transmission among K-12 schoolchildren can be reduced by interventions, says study

A new study reports the results of a model framed to explore the transmission of the delta variant among schoolchildren and the most effective intervention methods to minimize such spread.

Analysis of antibody titer decay following vaccination or SARS-CoV-2 infection

A new study focused on the decrease in antibody titers following two doses of BNT162b2 vaccine or SARS-CoV-2 natural infection in Israel.

Study: Women smoke fewer cigarettes than men but find it more difficult to quit

A study of more than 35,000 smokers has found that women smoke fewer cigarettes than men but are less likely to quit. The research is presented at ESC Congress 2021.

Novel CT scan-based approach indicates possible lung destruction in some people with asthma

A novel CT scan-based approach has revealed significant changes in a parameter indicating lung destruction in some asthmatics.

Scientists forecast healthcare burden of future COVID waves

The findings indicate that given the lower vaccine efficacy against the SARS-CoV-2 delta variant, France may face a large epidemic wave infecting 25% of the general population even with a 95% vaccine coverage. This, in turn, could affect the healthcare system in terms of hospital bed occupancy. The study is currently available on the medRxiv* preprint server.

Study on SARS-CoV-2 Delta breakthrough infections shows twice the risk as Alpha

A recent study conducted by Portuguese scientists has claimed that mRNA-based coronavirus disease 2019 (COVID-19) vaccines are less effective against the delta variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Moreover, in breakthrough infections by delta variant, vaccines are less effective in reducing viral loads. The study is currently available on the medRxiv* preprint server.

Reassuring news about the protection that SARS-CoV-2 vaccines offer

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines have proven effective at preventing COVID-19-related mortality and illness. Since no vaccine is 100% effective, breakthrough infections are likely to occur. New research by a group of scientists at Erasmus Medical Center and Radboud University in the Netherlands looked at vaccine-breakthrough infections in a large group of vaccinated healthcare workers (HCWs).

Study: Majority of hospital-acquired COVID-19 cases were contracted from other patients

The majority of patients who contracted COVID-19 while in the hospital did so from other patients rather than from healthcare workers, concludes a new study from researchers at the University of Cambridge and Addenbrooke's Hospital.

SARS-CoV-2 Delta likely to acquire resistance to wild-type spike vaccines

A new study published on the preprint server bioRxiv* explores the mechanism of the Delta variant's high infectivity and suggests a plausible pathway by which the Delta variant could escape from vaccine-induced immunity.

Compounds from medicinal mushrooms may be our future weapon against SARS-CoV-2

Certain steroid-like compounds from Taiwan's endemic medicinal mushrooms (known as antcins) may inhibit a host cell receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and, thus, prevent viral infection and subsequent development of the coronavirus disease (COVID-19), reports a new study published in the MDPI's journal Plants.

Researchers find clues to how lung damage develops in the aftermath of a respiratory infection

The deadliest time in a viral respiratory illness sometimes is actually after the virus is cleared from the body. Destructive processes that are set in motion during an infection crest in the weeks after the virus is defeated, leading to organ damage that can cause chronic illness or even death.

UC San Diego Health performed region’s first double lung transplant for a COVID-19 patient

On a July afternoon, Federico Gomez Gil, 56, is dressed in a short-sleeved, collared shirt, sweatpants and a baseball cap. He sits in a chair in a hospital room, surrounded by his wife and two daughters. Given the past five months, this is the moment of a lifetime — a new lifetime.
