Evidence suggests that COVID-19 is primarily an airborne disease. Yet the details of how transmission occurs are still debated and frequently misunderstood.
Only half of volunteers deliberately exposed to SARS-CoV-2 developed an infection. None developed serious symptoms, paving the way for further challenge trials.
The Scientist spoke with the UK’s chief veterinary officer, Christine Middlemiss, about this winter’s high bird flu prevalence, the effects of the disease, and efforts to combat it.
Dozens of researchers, including myself, worked for years to uncover that swine flu had leapt to humans from a pig in Mexico in 2009. We learned a lot about influenza evolution, pig farming, and outbreak risk along the way.
Seven years of surveillance and research revealed the complex history of the H1N1 virus that leapt from pigs to humans and sparked the global swine flu outbreak.
A preprint reports that the new SARS-CoV-2 variant multiplies faster in human bronchial tissue but slower in lung tissue than the Delta variant, potentially explaining how it’s spreading from person to person so quickly.
Preliminary studies suggest that existing vaccines falter in preventing symptomatic infections caused by the new coronavirus variant, but protection against severe disease is still high.
Epidemiological research suggests that a flu diagnosis might be one factor in the eventual onset of the neurodegenerative disease, but experts say it doesn’t prove a causal relationship.

While the weather isn’t currently the dominant factor driving SARS-CoV-2 transmission, experts say that in the future COVID-19 may become a disease of winter.
Multiple white tailed deer tested positive for SARS-CoV-2 likely transmitted from humans, a study finds, indicating the species could act as a reservoir for the virus.
Ebola virus was detected in samples from a child who died last week, the World Health Organization and Democratic Republic of the Congo’s Ministry of Health announce.
