Dexamethasone shown to upregulate innate and adaptive immune responses in COVID-19 acute respiratory distress syndrome patients

In a new study, researchers used per protocol bronchoalveolar lavage fluid (BALF) samples after intubation to evaluate the transcriptomic profiles of the local pulmonary host responses during early-stage severe coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (CARDS), non-COVID-19 ARDS, and sepsis.

Study demonstrates that intra-host SARS-CoV-2 variants with reduced infectivity are developed during infection

A new paper discusses the appearance of quasi-species in a single host with prolonged infection, with different rates of infectivity and sensitivity to neutralization by antibodies elicited by the Pfizer vaccine or those present in convalescent plasma.

Study reveals aerosol transmission of SARS-CoV-2 via floor drains

A new study investigated COVID-19 cases in an apartment complex in South Korea and explored the possibility of aerosol transmission without direct contact between infected individuals with the help of molecular phylogenetic analysis and epidemiological surveillance.

Nine-month survey of COVID-19 vaccine effectiveness in North Carolina

A new paper reports increased breakthrough infections with SARS-CoV-2, the agent behind the ongoing COVID-19 pandemic.

Study investigates whether immune responses to BNT162b2 vaccine differ in subjects with and without prior SARS-CoV-2 infection

A new paper published in the journal JCI Insight reports on the differential levels of immunity achieved in those with and without a history of prior infection with the virus following one and two doses of the earliest vaccines to be approved for emergency use.

Study identifies cellular receptors for alphaviruses shared across mosquitoes, humans, and animals

A new study led by researchers at Harvard Medical School has identified a set of cellular receptors for at least three related alphaviruses shared across mosquitoes, humans, and animals that host the virus.

Rapid antigen tests for SARS-CoV-2 have low overall rate of false-positive results

A timely new study investigated the incidence of false-positive results in a large sample of rapid antigen tests used to serially screen asymptomatic workers throughout Canada.

Pathogens turn off mitochondrial defense by hijacking a normal cellular response to stress

Mitochondria are known as energy suppliers for our cells, but they also play an important role in the defense against pathogens. They can initiate immune responses, and deprive pathogens of the nutrients they need to grow.

New model to identify biological markers in patients with COVID-19 and other illnesses

Investigators who recently developed a mathematical model that indicated why treatment responses vary widely among individuals with COVID-19 have now used the model to identify biological markers related to these different responses.

Study analyzes the impact of global trust in government due to the COVID-19 pandemic

In a week when the UK Prime Minister Boris Johnson has admitted to breaking Covid-19 lockdown rules, a new study has found that impartial, transparent and truthful government communications are fundamental for achieving and maintaining government trust during public health emergencies.

Pregnant women who contracted COVID-19 more likely to have poor birth outcomes

People who contracted COVID-19 while pregnant were more likely to have poor birth outcomes including preterm birth, small for gestational age, low birth weight, and stillbirth.

Mutations in SARS-CoV-2 Omicron variant promote cell binding

Researchers in Germany, based on their recent study published in the journal ChemBioChem, have proposed that the elevated occurrence of positively charged amino acids in specific domains of the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) Omicron variant spike protein improves viral binding to cellular negatively charged receptors aiding in enhanced infectiousness.

Monitoring rodents for SARS-CoV-2 and other coronaviruses, Hong Kong

A new study published in the Centers for Disease Control and Prevention’s Emerging Infectious Diseases journal has hypothesized that locations with positive SARS-CoV-2 in sewage could be used as potential surveillance targets to analyze if pestiferous urban rodents shed SARS-CoV-2 into the environment.

Topical antiseptic Acriflavine inhibits SARS-CoV-2 and other betacoronaviruses

A new study, published in the journal Cell Chemical Biology, has reported the discovery of acriflavine (ACF), an effective inhibitor of SARS-CoV-2. This drug is a mixture of trypaflavines (3,6-diamino-10-methylacridinium chloride and 3,6-diamino-3-methylacridinium chloride) and proflavine (3,6-diaminoacridine).

Cannabidiol may improve innate immune response against SARS-CoV-2

A recent study shows evidence that cannabidiol, an important active ingredient in the Cannabis sativa plant, can augment the antiviral innate immune response and prophylactically prime the innate antiviral response of cells – enabling in turn improved response against viruses such as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

CDC updates consumer webpage describing masks, respirators used to prevent COVID-19

CDC has updated our consumer webpage describing the types of masks and respirators used to prevent the transmission of SARS-CoV-2. Masking is a critical public health tool to prevent the spread of COVID-19, and it is important to remember that any mask is better than no mask.

Rapid antigen test for SARS-CoV-2 proves to be highly accurate for pediatric populations

In a large prospective study of just over 1,000 patients ages 17 and younger who were seen at the Baltimore Convention Center Field Hospital (BCCFH) testing site during a seven-month period last year, researchers from Johns Hopkins Medicine and collaborating institutions report that a rapid antigen test for SARS-CoV-2 — the virus that causes COVID-19 — proved highly accurate when compared to the established standard virus detection method: the polymerase chain reaction (PCR).

Even mild SARS-CoV-2 respiratory-only infection can cause long-term neurologic damage

A new bioRxiv* preprint study led by Michelle Monje of Stanford University in California finds that a mild COVID-19 infection can produce long-term neurological damage. Persistent cognitive complications are one of many symptoms of long COVID, and the latest results suggest the severity of COVID-19 induced brain fog is similar to cancer’s “chemobrain.”

Study shows Omicron less severe than Delta among COVID-19 hospitalized patients

New research posted to the medRxiv* preprint server suggests the Omicron variant produces less severe COVID-19 symptoms than earlier severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants.

UV-C light prevents airborne transmission of SARS-CoV-2

Researchers demonstrate that ultraviolet light-C (UV-C) effectively prevents airborne transmission of SARS-CoV-2.
