An influenza virus identified in pigs in China has a concerning mix of genes, but experts say there is no way to know if it will evolve to be transmissible between humans.

Microbiologist Maurice Hilleman foresaw the global spread of a novel influenza strain in 1957. His vaccine saved hundreds of thousands of lives.

Drugs targeting patients’ immune systems, rather than the virus itself, could be key to recovery from severe cases of the disease, some researchers suggest.

By studying influenza in mice and cells, researchers identify a glucose metabolism pathway critical to the dysregulated immune response that kills many infectious disease patients, including those with COVID-19.

The host transcriptional signature elicited by the coronavirus appears to be less robust and lacks the induction of key antiviral genes.

Random mutations in the SARS-CoV-2 pathogen’s genome help researchers track the spread and transmission of COVID-19, the disease it causes.

Roughly a quarter of 38 viral samples from people treated with Xofluza had mutations in their genomes that made the pathogens less susceptible to the drug.

The low-carb, high-fat diet increases the presence of gamma-delta T cells in the animals’ lungs, improving a mucus barrier against the virus.

Antibiotics disrupt the immune response to the influenza vaccine in people who haven’t recently had exposure to the virus or immunization.
