Antiviral cocktail may help treat mild COVID-19 patients

The skyrocketing number of cases due to the coronavirus pandemic has taken a massive toll on the health systems in many countries. Since the advent of the coronavirus disease (COVID-19), hundred of research teams are racing to find an effective vaccine and treatment to combat the deadly infection. Now, a team of researchers in Hong Kong suggests that combining three existing antivirals may help treat COVID-19 patients.

SARS-CoV-2 could spread through surface of the eyes

Researchers from Johns Hopkins University School of Medicine have found that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus could spread via ocular or eye surfaces. This is because the receptor where the virus binds – the ACE2, is also expressed on human eyes, they note.

Genomic sequences from all over the world help fight SARS-CoV-2

As the COVID-19 pandemic rages across the world, killing hundreds of thousands and infecting over 4.1 million, researchers are racing against time to understand the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The SARS-CoV-2 genome has now been sequenced in many different regions of the world, and researchers are collaborating by sharing information to better understand the make-up and mutations that the virus has undergone.

Varied performance of SARS-CoV-2 antibody tests in detecting protective immunity

The performance of commercially available serological tests in real patient samples and the correlates of immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) provided by IgG antibodies are still a matter of debate. A new bioRxiv preprint paper cross-examines the performance of several assays and proclaims the plaque reduction neutralization test (PRNT) as a method of choice.

Keeping the COVID plague at bay: How California is protecting older veterans

Dr. Vito Imbasciani has been at war with viruses since he was 5. Growing up near the U.S. Military Academy at West Point in New York, he contracted polio in 1952 and couldn't walk for two months. In medical school in Vermont 30 years later, he witnessed AIDS steal the lives of otherwise healthy gay men.

Italy develops vaccine candidate that neutralizes SARS-CoV-2 in mice

As the world grapples with the coronavirus disease (COVID-19), scientists race to develop treatments and vaccines to combat the viral infection. Though many ongoing trials show promise in fighting the novel coronavirus, Italian researchers claim they have developed a vaccine that can neutralize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in animal cells.

No evidence COVID-19 is spread by fecal-oral transmission

A new study published on the preprint server medRxiv* in May 2020 shows that in patients who test positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in pharyngeal and fecal samples, the virus persists longer in the fecal samples than in the pharyngeal samples. However, fecal-oral transmission does not appear to occur.

Human neutralizing antibody pair blocks COVID-19-ACE2 binding

With the ongoing COVID-19 pandemic carving its deadly path across the world, and no end in sight in the immediate future, researchers are working furiously to bring out an effective therapeutic drug or vaccine that will stop the virus in its tracks.

COVID-19 could accelerate activation of dormant tuberculosis (TB)

The ongoing COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has thrown much of the world into disarray, with over 4 million people reported infected and well over 282,000 deaths. A new study published on the preprint server bioRxiv in May 2020 suggests that the long-term impact of the virus could include activation of dormant bacterial infections like tuberculosis (TB).

Neutralizing SARS-CoV-2 via S protein

A new study published on the preprint server bioRxiv* in May 2020 reports on a method to block severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by destroying its main spike protein, which is responsible for attachment to the host cell membrane.
