Symptoms documented in cases of long COVID are wide ranging and variable.

A year and a half into the pandemic, the long-term effects of SARS-CoV-2 infection are garnering more research attention as millions of long COVID patients emerge.

Officials say it’s not yet clear whether this case is linked to an outbreak in Guinea earlier this summer.

Cases of influenza and other respiratory viruses sank dramatically during the pandemic, with potential implications for both people and pathogens.  

Take a break from the bench to puzzle and peruse.

A comparison of interferon-related genes across 20 primate genomes reveals differences in the speed at which they evolve and new targets for antiviral discovery efforts.

Scientists are on the hunt for a shot that will protect against not only SARS-CoV-2, but other members of its family that may emerge in the future.

Researchers at Imperial College London and the University of Oxford are exposing healthy volunteers to SARS-CoV-2 for science.

The World Health Organization–led program will promote equity in addition to facilitating access to samples, a WHO official involved in the project tells The Scientist.

New genomic analyses reveal that piscine orthoreovirus first came to the Pacific in 1989, around the same time that salmon farms in the area started importing Atlantic salmon eggs from Europe.

A letter signed by 18 researchers argues that hypotheses about zoonotic spillover or accidental lab release both “remain viable” in the absence of additional evidence.

By avoiding the production of antibodies, something vaccines ordinarily induce, the immunization sidesteps the problem of antibody-dependent enhancement, which can amplify infection by a similar virus and is known to occur with dengue and Zika.

While some experts speculate the variant could be partially responsible for India’s current surge in SARS-CoV-2 infections, information about the effects of its mutations is only beginning to emerge.

An automated wastewater monitoring technique could enable researchers to predict outbreaks of the virus up to a week in advance.

Researchers use magnetic nanoparticles and liquid-handling robots in an effort to detect COVID-19 outbreaks early.

In a trio of studies, researchers follow up on a 40-year-old finding that certain bacteriophages replace adenine with so-called diaminopurine, perhaps to avoid host degradation.

Researchers involved in a long-term project to identify viruses of concern have now assessed the risk factors that could help forecast which pathogens are the most likely to spillover from wildlife to people.

Martha Nelson of the National Institute of Allergy and Infectious Diseases talks about the need to balance data sharing and patient privacy concerns when tracking the spread of variants.

Genetic analyses suggest that the virus came from a patient who survived the 2013–2016 West African outbreak.
