FDA Clears Use of Monkeypox Testing Equipment
FDA – FDA issued an Emergency Use Authorization (EUA) to Abbott Molecular, Inc., for the Alinity m MPXV, a real-time polymerase chain reaction (PCR) test intended to detect monkeypox DNA using lesion swab specimens from individuals suspected of monkeypox virus infection. The Alinity m MPXV test is the first commercial test kit to be authorized for detection […]

Long COVID: Scientists find 20 blood protein ‘signatures’ that may point to risk
Med News Today – Researchers published their findings comparing blood samples from healthcare workers who had contracted SARS-CoV-2 and healthcare workers who had not. They found that blood protein levels within six weeks of contracting SARS-CoV-2 could predict long COVID incidence. “These changes in the blood that we observe shortly after infection indicate how the […]

FDA – FDA added important information to the authorized Fact Sheets for Evusheld (tixagevimab co-packaged with cilgavimab) to inform health care providers and individuals receiving Evusheld of the increased risk for developing COVID-19 when exposed to variants of SARS-CoV-2 that are not neutralized by Evusheld. Detailed neutralization data can be found in the revised authorized Fact […]

Wild Birds in North America Are Dying Like Never Before
The Atlantic – Scientists are concerned for North American wildlife as the worst avian flu outbreak since 2015 rages on. The July 5 trip was routine: From the deck of an airboat, two wildlife biologists scanned the cattail marsh—one of many seasonal wetlands in the Sacramento National Wildlife Refuge—on their weekly lookout for sick or […]

What are the differences in transmissibility between novel and emerging SARS-CoV-2 variants?
Medical News – Currently, the majority of reporting of secondary attack rates (SAR) in coronavirus disease 2019 (COVID-19) have defined secondary infection as recent polymerase chain reaction (PCR) positivity in a contact who is displaying symptoms. By only including those who are symptomatic while having detectable viral ribonucleic acid (RNA) during sampling, this method undercounts […]

Repurposing existing drugs to fight new COVID-19 variants
Michigan State University – MSU researchers are using big data and AI to identify current drugs that could be applied to treat new COVID-19 variants. Finding new ways to treat the novel coronavirus and its ever-changing variants has been a challenge for researchers, especially when the traditional drug development and discovery process can take years. […]

Zoonotic diseases like COVID-19 and monkeypox will become more common, experts say
NPR – Cases of monkeypox are on the rise in the U.S., with about 67,600 global cases, including about 25,500 in the U.S. Simultaneously, the world is still facing a COVID-19 pandemic, despite the number of cases tapering off. Researchers say these types of viruses, known as zoonotic diseases, or ones that spread between humans and animals, will […]

Remdesivir resistance in transplant recipients with persistent COVID-19
Clinical Infectious Diseases – New mutations conferring resistance to SARS-CoV-2 therapeutics have important clinical implications. We describe the first cases of an independently acquired V792I RNA-dependent RNA polymerase mutation developing in renal transplant recipients after remdesivir exposure. Our work underscores the need for augmented efforts to identify concerning mutations and address their clinical implications. Download […]

SARS-CoV-2 mutation leads to resistance to remdesivir in 2 patients
CIDRAP – A report published yesterday in Clinical Infectious Diseases describes a new SARS-CoV-2 mutation that confers resistance to the COVID-19 antiviral drug remdesivir in two persistently infected kidney transplant recipients treated with immunosuppressive drugs. NYU researchers identified the V792I RNA-dependent 25 RNA polymerase mutation in the transplant patients, who were hospitalized and experienced life-threatening COVID-19 complications […]

These scientists traced a new coronavirus lineage to one office — through sewage
Nature – Virologist Dave O’Connor admits that he was getting desperate when he started asking dog owners for poo samples. For much of 2022, O’Connor, at the University of Wisconsin–Madison, and his colleagues have been tracking a heavily mutated variant of SARS-CoV-2, the virus that causes COVID-19. Early this year, they discovered the variant in […]
