CDC withdraws guideline on SARS-CoV-2 airborne spread

The U.S. Centers for Disease Control and Prevention (CDC) recently published a new guideline, recognizing that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can spread via aerosols. Now, the health agency takes back its statement by deleting the updates published on Sept. 18.

Acquisition of a natural mutation primes SARS-CoV-2 for neutralization by a cross-reactive antibody

A team of scientists from the United States reveals that the acquisition of a natural mutation makes severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) susceptible to neutralization by a cross-reactive SARS-CoV antibody. The study is currently available on the bioRxiv* preprint server.

Confirmed early re-infection with SARS-CoV-2

As scientists strive to develop commercially viable and effective antivirals and vaccines to counter the growing COVID-19 pandemic, there is considerable uncertainty about how long and how durable the immunity induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is. A new paper recently published in the journal Clinical Infectious Disease in September 2020 reports a confirmed case of re-infection with this virus following recovery.

Parkinson's disease diagnosed after SARS-CoV-2

As the COVID-19 pandemic continues to spread, new and unusual chronic sequelae of the disease are cropping up in many medical practices. Now, a new case paper published in The Lancet in September 2020 describes a case of new-onset Parkinson's disease following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

How COVID-19 flew to Greece

A recent study published in the journal Travel Medicine and Infectious Disease in September 2020 reports a series of cases following travel on a commercial airliner that heralded the earliest imported COVID-19 infections in Greece.

Study shows effectiveness of UV-C light for killing COVID-19 on N95 respirators

Dermatology researchers at Henry Ford Health System, in collaboration with a team at the University of Michigan, have demonstrated that certain N95 respirators tainted with COVID-19 can be effectively and safely decontaminated for reuse using ultraviolet-C light (UV-C), a method commonly utilized for treating rare skin diseases.

Wastewater analysis predicts COVID-19 spread

The researchers from Yale University provided an outline of the spread of the infection in the community. Their study titled, “Measurement of SARS-CoV-2 RNA in wastewater tracks community infection dynamics,” is published in the latest issue of the journal Nature Biotechnology.

COVID-19 can affect the retina

Now, a new study published in the journal EClinicalMedicine shows that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes the coronavirus disease (COVID-19), targets the retina.

Respiratory specimens testing positive for SARS-CoV-2 decrease in the U.S., CDC report

In the report, published on Sept. 18, the CDC shows that indicators tracking COVID-19 activity continued to decline or remain stable. Still, two regions say a slight increase in the percentage of specimens testing positive for SARS-CoV-2. Meanwhile, four regions reported a slight increase in the percent of outpatient or emergency department visits for influenza-like illness (ILI).

Inhibition of SARS-CoV-2 with antisense oligonucleotides

A part of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral RNA is highly conserved. Researchers have used this as a target for designing antisense oligonucleotide gapmers to cleave the RNA and disrupt virus replication. Their research is published as a preprint on the online server bioRxiv in September 2020.

COVID-19 mitigation efforts significantly decrease influenza activity

The mitigation strategies implemented to curb the spread of COVID-19 appears to reduce the transmission of influenza in the United States, Australia, Chile, and South Africa. These strategies may augment influenza vaccines, especially for high-risk populations during the seasonal influenza transmission.

Screening university students could reduce community COVID-19 burden

Researchers in Canada and the United States report that screening students for infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as universities re-open this fall could reduce the burden of coronavirus disease 2019 (COVID-19) in the broader community.

A cost-effective scalable production of SARS-CoV-2 RBD in yeast

A new study by the Argentinian AntiCovid Consortium and published in the preprint server bioRxiv* in September 2020 reports on the successful characterization of the conformation and stability of the SARS-CoV-2 spike protein receptor-binding domain (RBD) in two different cell systems. This may help to accelerate the development of vaccines and neutralizing antibodies.

Research underlines SARS-CoV-2 N-terminal domain of Nsp1 as a potential drug target

A recent study reveals how the non-structural protein 1 (NSP1) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) plays a crucial role in inhibiting the host cell protein synthesis but simultaneously facilitating the viral protein synthesis.

Oncology nurses should be routinely tested for SARS-CoV-2, warn researchers

Researchers from the NHS Foundation Trust, University of Cambridge and Cambridge Clinical Laboratories have warned that until a vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) becomes available, antigen and antibody testing should be carried out among oncology nurses as part of routine patient care.

CDC updates coronavirus guidelines to recognize airborne spread

Early on in the pandemic, it was thought that the virus was only spread via respiratory droplets. However, scientific research soon showed it also to be an airborne virus. Now, the U.S. Centers for Disease Control and Prevention (CDC) has updated its guideline, acknowledging that the virus can hang in the air, fueling its spread.

COVAM assay may help select convalescent plasma units for treatment of acute COVID-19

A recent study published on the preprint server bioRxiv* seeks to establish the pattern of antibody reactivity in COVID-19 convalescent plasma (CCP), which is widely being used as a therapy for seriously ill COVID-19 patients.
