Scientists tried to give people COVID — and failed
Nature Researchers deliberately infect participants with SARS-CoV-2 in ‘challenge’ trials — but high levels of immunity complicate efforts to test vaccines and treatments. When Paul Zimmer-Harwood volunteered to be intentionally infected with SARS-CoV-2, he wasn’t sure what to expect. He was ready for a repeat of his first brush with COVID-19, through a naturally acquired […]

Do Our Flu Antivirals Work on H5N1?
MedPage Today With avian influenza A (H5N1) infecting more mammals than ever before — including U.S. dairy cattleopens in a new tab or window — infectious disease experts are paying close attention to whether current influenza antivirals would be effective should H5N1 adapt to humans. All influenza viruses have extremely similar internal mechanisms for reproduction, William Schaffner, […]

Deforestation pushes animals in Uganda forest to eat virus-laden bat poo
BBC Animals in a Ugandan forest have been eating bat poo laden with viruses after tobacco farming wiped out their usual food source, a study has found. A virus linked to Covid-19 was among the 27 identified in the poo eaten by chimpanzees, antelopes and monkeys. Researchers say this finding sheds light on how new […]

Utah researchers collect samples to map spread of respiratory illness through dirt, dust
KSL.com A team of University of Utah researchers is studying a fungal respiratory infection they say is spreading through the soil and dust in Utah. Researchers don’t yet know exactly which areas of the state have valley fever, but professor of epidemiology Katharine Walter said the fungus could spread further as the climate changes. An […]

Upper Respiratory Tract Disease in a Dog Infected by a Highly Pathogenic Avian A/H5N1 Virus
Emerging Viral Zoonoses In summer 2023, during an outbreak of highly pathogenic avian influenza (HPAI) in cats in Poland, a 16-year-old dog was presented to the veterinary clinic with persistent, debilitating, dry cough, submandibular lymphadenomegaly, mild serous nasal discharge, and left apical heart murmur. A preliminary diagnosis of kennel cough was made and the treatment […]

Large-scale phenotyping of patients with long COVID post-hospitalization reveals mechanistic subtypes of disease
Nature One in ten severe acute respiratory syndrome coronavirus 2 infections result in prolonged symptoms termed long coronavirus disease (COVID), yet disease phenotypes and mechanisms are poorly understood1. Here we profiled 368 plasma proteins in 657 participants ≥3 months following hospitalization. Of these, 426 had at least one long COVID symptom and 233 had fully recovered. […]

Cornell scientists identify bird flu infecting dairy cows
Cornell University Cornell virology experts are sequencing the bird flu virus that struck cows in the Texas panhandle last week, after work at Cornell and two other veterinary diagnostic laboratories found the highly pathogenic avian influenza (HPAI) virus in cattle samples, a first for this species. Sequencing of the virus may help scientists understand why […]

Zoonotic Viruses: Humans More Often a Source Than a Sink
Genetic Engineering & Biotechnology News Zoonotic viruses fill us with dread—and rightly so. Such viruses have been known to spread from animals to human hosts, transmitting deadly diseases such as Ebola, rabies, and bird flu. And according to virologists and other scientists with relevant expertise, the SARS-CoV-2 virus, the source of the COVID-19 pandemic, is […]
