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 found in semen of COVID-19 patients

Since the novel coronavirus, now called the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in December 2019, viral loads have been detected in body fluids, such as urine samples, saliva, stool samples, and in the gastrointestinal tract. Now, a new study reveals the SARS-CoV-2 virus in semen.

COVID-19 and exposure to air pollution

A scientist from the Netherlands has worked on a study that looked at the association between COVID-19 infections and exposure to air pollution. Researcher Bo Pieter Johannes Andrée’s study titled “Incidence of COVID-19 and Connections with Air Pollution Exposure Evidence from the Netherlands” was released prior to the peer review process on the online server Medrxiv.

Dead virus fragments are causing COVID-19 reinfection false positives

The coronavirus disease (COVID-19) has ravaged across the globe, infecting a staggering 3.5 million people, and taking over 251,000 lives. One of the most significant concerns in this global pandemic is the possibility of reinfection as previous reports in South Korea and Japan show people testing positive with the coronavirus again.

Low molecular weight heparins inhibit SARS-CoV-2 cell invasion

A recent paper available on the preprint server bioRxiv* reports preliminary data on the ability of low molecular weight heparins to interact with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), elicit structural changes in its key proteins and subsequently halt cell invasion.

Study with twins shows COVID-19 symptoms have genetic contribution

A new study published on the preprint server medRxiv from King's College, London, suggests that an individual's genetic makeup may contribute to how much a person is likely to be affected by COVID-19, or whether they are likely to be infected at all.

CRISPR technology mobilized for rapid COVID-19 diagnosis

A group of authors from the United States published a study in the scientific journal Nature Biotechnology in which they have described a CRISPR-Cas-based approach for rapid and accurate diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection – without the need for complex laboratory infrastructure.

Hydroxychloroquine and azithromycin treatment in 80 COVID-19 patients: short-term outcomes

The COVID-19 pandemic is still spreading around the world and affecting nearly 2.4 million people, with over 164,000 dead so far. With neither vaccine nor proven therapeutic drug being available so far, the need of the hour is for effective treatment. Now, a new study reports the potential usefulness of a combination of hydroxychloroquine and azithromycin as a treatment in mild cases of COVID-19 infection and urges the need for further evaluation and widespread use if its findings are confirmed.

Gimsilumab trial starts in first US patient with ARDS and COVID-19

The first American patient with COVID-19 and acute respiratory distress syndrome (ARDS) has been put on the drug gimsilumab at Temple University Hospital, as part of the BREATHE clinical trial. The trial, sponsored by Roivant Sciences, will evaluate the effectiveness of intravenous gimsilumab in preventing death in patients with COVID-19 and ARDS.
