Virome Sequencing Identifies H5N1 Avian Influenza in Wastewater from Nine Cities
Preprint server Avian influenza (serotype H5N1) is a highly pathogenic virus that emerged in domestic waterfowl in 1996. Over the past decade, zoonotic transmission to mammals, including humans, has been reported. Although human to human transmission is rare, infection has been fatal in nearly half of patients who have contracted the virus in past outbreaks. […]

The Conversation The last pandemic was bad, but COVID-19 is only one of many infectious diseases that emerged since the turn of this century. Since 2000, the world has experienced 15 novel Ebola epidemics, the global spread of a 1918-like influenza strain and major outbreaks of three new and unusually deadly coronavirus infections: SARS, MERS and, of course, COVID-19. Every year, researchers […]

White House overhauls rules for risky pathogen studies
Science New policies for gain-of-function and “dual-use” research will cover broader swath of experiments. The White House is tightening federal oversight of so-called gain-of-function (GOF) studies that could enhance risky viruses in ways that increase their ability to cause a pandemic. It is also overhauling rules for a broader category of federally funded research on […]

Chinese scientist who first published COVID sequence stages protest after being locked out of lab
AP The first scientist to publish a sequence of the COVID-19 virus in China staged a sit-in protest outside his lab after authorities locked him out of the facility — a sign of Beijing’s continuing pressure on scientists conducting research on the coronavirus. Zhang Yongzhen wrote in an online post Monday that he and his team had […]

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 […]

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. […]
