Researchers develop a novel method to test for COVID-19 antibodies

When Dr. Stephen Smith of Seattle Children's Research Institute came down with muscle aches, gastrointestinal distress and a sudden loss of smell in late February, he suspected he had COVID-19.

Study raises new questions about viral load in asymptomatic children with COVID-19

New questions are at the forefront as a study published in the Journal of Clinical Microbiology from nine children's hospitals finds that most asymptomatic children who tested positive for COVID-19 had relatively low levels of the virus compared to symptomatic children.

DNA vaccine-induced antibodies neutralize SARS-CoV-2

The coronavirus disease (COVID-19) is far from over as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to ravage across the globe. With the vast spread of the virus, many countries who reported flattening the curve over the past months have reported clusters of new cases and second waves of the outbreak.

$2 million NCI SeroNet grant aims to increase diversity in COVID-19 immunology research

A new, $2 million grant from the NCI Serological Sciences Network for COVID-19 (SeroNet) is aimed at enhancing representation of Black and Hispanic people in SARS-CoV-2 immunology research through the use of storytelling--an approach in which community members become "video stars" and provide honest messages about the importance of being represented in COVID-19 research studies.

Study reveals developmental changes of the immune system during first week of life

Within the womb, a human fetus benefits from the protection of the placenta, limiting their contact with pathogens.

First antiviral treatment for COVID-19 receives FDA approval

Today, the U.S. Food and Drug Administration approved the antiviral drug Veklury (remdesivir) for use in adult and pediatric patients 12 years of age and older and weighing at least 40 kilograms (about 88 pounds) for the treatment of COVID-19 requiring hospitalization.

COVID-19 patient's immune response may underlie the effects on the nervous system

It is probably the immune response to, rather than the virus in itself, that causes sudden confusion and other symptoms from the nervous system in some patients with COVID-19. This is shown by a study of cases involving six Swedish patients, now published in the journal Neurology.

Study sheds light on working principles of various advanced biosensing technologies

The COVID-19 pandemic is undoubtedly the most challenging global health burden since the 2nd World War. The pandemic has raised social awareness on the importance of effective and timely diagnosis that may help minimize the risk of contracting and spreading COVID-19.

Hydroxychloroquine does not prevent COVID-19 in health care workers, trial shows

University of Minnesota Medical School physician researchers studied hydroxychloroquine as a treatment to prevent COVID-19 for those with high-risk for exposure to the virus - health care workers.

Increasing levels of light pollution could impact transmission of diseases through mosquitoes

Artificial light abnormally increases mosquito biting behavior at night in a species that typically prefers to bite people during the day, according to research from the University of Notre Dame that was published in The American Journal of Tropical Medicine and Hygiene.

Researchers conduct review on viral shedding of SARS-CoV-2

A review of dozens of studies by researchers at Oregon Health & Science University and Oregon State University suggests that people may shed virus for prolonged periods, but those with mild or no symptoms may be infectious for no more than about 10 days.

New smart surface pulls critical COVID-19 marker from the blood

When COVID-19 attacks, the immune system produces a cytokine, or protein, called Interleukin-6 (IL-6), whose concentrations can offer vital information about a patient's level and stage of infection.

Mortality rates higher for U.S. working-age residents living in rural areas

A recent study by Syracuse University sociology professor Shannon Monnat shows that mortality rates are higher for U.S. working-age residents who live in rural areas instead of metro areas, and the gap is getting wider.

Researchers explore new method to monitor the effectiveness of HIV treatment at home

Development of a new method to monitor the effectiveness of human immunodeficiency virus (HIV) treatment at home instead of in hospitals is underway by Penn State researchers.

Older males who have recovered from COVID-19 are best plasma donors for treatment

Sex, age, and severity of disease may be useful in identifying COVID-19 survivors who are likely to have high levels of antibodies that can protect against the disease, according to a new study co-led by researchers at Johns Hopkins Bloomberg School of Public Health.

New inhaled treatment may lead to self-administered therapy for COVID-19

An inhaled treatment against the SARS-CoV-2 virus may lead to a future self-administered therapy for COVID-19, the pandemic that has killed more than 1 million people worldwide.

Promising interim results for Sinopharm's inactivated whole-virion SARS-CoV-2 vaccine

The COVID-19 pandemic has led to intensive scientific efforts to bring about an effective vaccine for global distribution. Many different vaccine design approaches are underway. A recent study published in the journal The Lancet Infectious Diseases in October 2020 reports a potentially successful inactivated virus vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Scientists find striking acceleration in medieval plague transmission over 300 years

McMaster University researchers who analyzed thousands of documents covering a 300-year span of plague outbreaks in London, England, have estimated that the disease spread four times faster in the 17th century than it had in the 14th century.

New lab test for detection of SARS-CoV-2 antibodies gives results more quickly than existing assays

Knowing you have developed antibodies against the SARS-CoV-2 virus after recovering from COVID-19 doesn't tell you everything about your immunity.

Cytotoxic NK cells also have immunological memory function

Good news for the human immune system: researchers from MedUni Vienna's Departments of Dermatology and Surgery have managed to ascribe an immunological memory function to a subset of cytotoxic NK cells, which have hitherto been regarded as antigen-non-specific.
