Showers, toilets and washbasins may act as SARS-CoV-2 reservoirs despite low environmental transmission

In their new research paper currently available on the medRxiv* preprint server, scientists from the University of Bonn in Germany demonstrated that indirect environmental transmission most likely plays only a minor role in the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, certain potentially neglected viral reservoirs have to be taken into account when introducing epidemiological measures.

Deep vein clots in critical COVID-19 illness

A new research paper published in the journal JAMA Network Open in May 2020 reports a high incidence of deep vein clots in patients with severe COVID-19 at a single French medical center. This could indicate the need for systematic anticoagulant therapy in these patients as a preventive measure.

Anosmia and changes in brain MRI in COVID-19

Even as the COVID-19 pandemic was sweeping across the world, new symptoms and clinical presentations appeared, often confusing the picture. A case report from Italy, published in the journal JAMA Neurology in May 2020, shows that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be a neurotropic virus, and may cause infection to present primarily with anosmia.

How susceptible are domestic animals to SARS-CoV-2?

A recent paper by Chinese researchers, published in the leading journal Science, shows that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) does not replicate well in dogs, pigs, chickens, and ducks; however, ferrets and cats are easily infected, and cats may transmit the virus via an airborne route.

Study reports a low prevalence of COVID-19 in pregnant women

New data from two studies show the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among pregnant women is low, but they still need to take extra precautions.

5-day Remdesivir dose works as well as the 10-day dose in COVID-19, study finds

With more than 5.8 million people infected with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the search is on for an effective SARS-CoV-2 vaccine or drug to treat COVID-19 disease.

Genomic variation and descent of SARS-CoV-2 strains in India

The pandemic of COVID-19 that is still affecting over 188 countries and territories the world over has taken over 359,000 lives in just under five months, while affecting at least 5.8 million people. Different strains have diverged from the original strain detected in Wuhan, China.

SARS-CoV-2 RNA in blood tests not associated with infectious virus

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has challenged hospitals and laboratory services worldwide. Diagnostic testing for SARS-CoV-2 initially lagged but is now primarily based on the use of reverse transcriptase-polymerase chain reaction (RT-PCR) to detect viral nucleic RNA in the samples. However, viral RNA has also been reported in several small series of cases, though its significance and frequency remain unclear.

Researchers develop rapid electro-optical test to identify COVID-19 carriers

Ben-Gurion University of the Negev's Prof. Gabby Sarusi has developed a one-minute electro-optical test of nose, throat, or breath samples that will identify both asymptomatic and affected carriers of the COVID-19 virus in under one minute with greater than 90% accuracy.

Researchers warn against false negatives in COVID-19 diagnostic test

One of the most commonly used diagnostic tools, particularly during this pandemic, is the reverse transcriptase-polymerase chain reaction test (RT-PCR), which uses a person's respiratory sample to detect viral particles and determine if the person may have been exposed to a virus.

Heparin resistance among COVID-19 patients admitted to ICU

A new study has shown that COVID-19 patients admitted to the Intensive care unit may be resistant to the naturally occurring anticoagulant Heparin. The study titled, “Heparin resistance in COVID‑19 patients in the intensive care unit,” was published in the latest issue of the Journal of Thrombosis and Thrombolysis.

Novel testing system predicts outcomes in patients with sepsis

More than 1.7 million Americans develop sepsis each year, and more than 270,000 die from it. The condition--which happens when the body has an extreme response to a bacterial or viral infection, causing a chain reaction that can lead to organ failure and death--has few strategies for treatment.

Portable analyzer rapidly detects anti-virus antibody in blood serum

Researchers have succeeded in detecting anti-avian influenza virus antibody in blood serum within 20 minutes, using a portable analyzer they have developed to conduct rapid on-site bio tests. If a suitable reagent is developed, this technology could be used to detect antibodies against SARS-CoV-2, the causative virus of COVID-19.

Changes in antibodies and RNA shedding during early SARS-CoV-2 infection

As the COVID-19 pandemic and its far-reaching implications continue to unfold globally and disrupt our normal way of life, scientists and researchers are racing to find an appropriate vaccine or therapeutic drug. This process involves understanding how the virus interacts with the host cell, the dynamics of the host immune response, and the eventual outcome.
