Viral shedding among pre-symptomatic COVID-19 patients finds study

Researchers from Bangalore, India, have found that 68 percent of pre-symptomatic patients with COVID-19 may be shedding the virus and potentially infecting others. Their study titled, “Quantitative COVID-19 infectiousness estimate correlating with viral shedding and culturability suggests 68% pre-symptomatic transmissions,” was published on the open-access preprint server Medrxiv.

Viral shedding seen in plasma donors who have recovered from COVID-19

Researchers from the University of Wisconsin-Madison have found that plasma donors who have recovered from the deadly COVID-19 infection were still shedding viral RNA. This could be significant they write in their article titled, “Prolonged viral RNA shedding after COVID-19 symptom resolution in older convalescent plasma donors,” that is published on the preprint server Medrxiv* prior to peer review.

Antiviral agent accelerates virus clearance in cases of COVID-19

A team of researchers from have found an antiviral therapy that seems to be an effective treatment for patients with moderate coronavirus disease 2019 (COVID-19).

COVID-19 and food insecurity in the U.S.

A new paper published on the preprint server medRxiv* in May 2020 reports that the measures taken to block the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) such as social distancing and lockdown are associated with widespread effects on food security in the US state of Vermont.

SARS-CoV-2 will infect 250 million people in Africa

A study conducted by the World Health Organization (WHO) has predicted that the coronavirus will infect almost one-quarter of a billion people in Africa during the first year of the pandemic. Unless immediate measures are taken to control the spread of the virus, as many as 190,000 of them are likely to die, the researchers warn.

New insights into SARS-CoV-2 viral diversity

The first comprehensive, large-scale analysis available on the preprint server bioRxiv attempted to identify specific genomic signatures of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strains within and across individual hosts – revealing recombination events, specific geographic profiles, as well as multi-strain and/or superinfections characteristic for the coronavirus disease (COVID-19) pandemic.

Continuously active antiviral coating may reduce the spread of COVID-19

Surfaces coated with a quaternary ammonium polymer have remarkable antiviral properties. They may even be capable of reducing the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in areas with high risk for contamination, such as indoor environments or public places. University of Arizona researchers explain the antiviral potential of these in a new study published on the preprint server medRxiv.

Research reveals how long SARS-CoV-2 survives on surfaces, in feces and urine

A new study published on the preprint server medRxiv* in May 2020 shows that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 disease can remain viable for a maximum of one week on smooth environmental surfaces, for several hours in human feces, and for a maximum of 4 days in human urine. This knowledge could help guide disinfection policies to control the virus spread.

Relaxation of social and physical distancing measures may result in profound mortality

Even as the world struggles to live and make a living, faced with the dual threat of a rapidly spreading viral illness and economic slowdown, a new study published on the preprint server medRxiv in May 2020 says that relaxing non-pharmacological interventions will allow the SARS-CoV-2 virus to become endemic.

Low albumin levels could predict poor outcome in COVID-19

A Spanish study has revealed that COVID-19 patients who have a low level of albumin have a poorer outcome compared to those with normal levels of blood albumin. The study titled, “Low albumin levels are associated with poorer outcomes in a case series of COVID-19 patients in Spain: a retrospective cohort study,” was released prior to peer-review on the open-access preprint server site Medrxiv*.

Leave packages unopened and untouched for 72 hours to prevent the spread of COVID-19

Researchers have advised that people need to leave their parcels and packages unopened and untouched for 72 hours to help stop the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 disease. The virus, as is evident from the raging pandemic across the world, is highly infectious and could survive on surfaces for up to 72 hours.

COVID-19 lockdown exit strategies: deliverance or disaster?

A new study by researchers at the University of Cambridge, Universidad de Sevilla, and the University of Massachusetts, published on the preprint server medRxiv in May 2020, shows that it is essential to choose a restrictive exit strategy while easing COVID-19 lockdowns, because failure to do so may lead to catastrophic results.

Researchers identify CoV Mac1 proteins as a potential SARS-CoV-2 drug target

A recent study by researchers at the University of Kansas and published on the preprint server bioRxiv* reveals that Mac1 protein implicated in the infection process of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has a strikingly similar structure and activity in all coronaviruses – suggesting that possible future treatments targeting this protein may exert broad antiviral activity.

Should school closures related to COVID-19 be continued long-term?

Since the coronavirus disease 2019 (COVID-19) outbreak was identified in Wuhan, China, in December 2019, many countries have introduced restrictive measures to curb the circulation and spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Placentas of pregnant women with COVID-19 showed abnormalities

A study conducted by researchers at Northwestern University, Chicago, has found that the placentas of pregnant women who were infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) showed abnormalities, compared with those of uninfected women.

Study shows why older individuals are vulnerable to COVID-19

A group of tiny RNA that should attack the virus causing COVID-19 when it tries to infect the body are diminished with age and chronic health problems, a decrease that likely helps explain why older individuals and those with preexisting medical conditions are vulnerable populations, investigators report.

Study explores whether senicapoc drug can mitigate lung damage in COVID-19 patients

Scientists around the globe are working to identify approved and investigational drugs that can be repurposed to treat COVID-19.

New rapid CRISPR-based test for sensitive SARS-CoV-2 detection

A new study reports the approval of a new CRISPR-based coronavirus test that is both sensitive and rapid and intended to help reduce the time required to test symptomatic or potentially contagious cases.

Johns Hopkins offers a free online course to become a contact tracer

Aside from mass testing, one of the most important methods to curb the transmission of the novel coronavirus is through extensive contact tracing. Now there's an opportunity to become a contact tracer as the Johns Hopkins Bloomberg School of Public Health has launched a six-hour online course.

Organ transplantations plummet amid coronavirus pandemic

The coronavirus disease has spread rapidly across nearly all countries across the globe, with more than 4.25 million people infected. The pandemic has taken a toll on the lives of people, especially those in locked down nations. Aside from the negative impact on economic and social aspects, patients who are sick with other diseases may also suffer from the effects of the pandemic.
