XEC is a recombinant variant, meaning it’s a hybrid of two previously existing variants. Genomic data suggests it’s making up around 5% of cases in Australia – but it may grow.
Infectious diseases can spill over from animals to humans as well as spill back. Each cross-species transmission gives pathogens a chance to evolve and spread even further.
An epidemiologist makes the case that a rush of research to stop a swine flu outbreak led to an accidental lab release of an extinct virus. Preparing for one pandemic triggered a different one.
Summer 2024 saw a big surge of COVID-19 cases. While COVID-19 is not the emergency it once was, it’s still a health threat, and we’d be wise to reduce our risk of getting it.
An Ohio law targeting student suspensions had a happy side effect. Requiring schools to use a positive approach to discipline reduced chronic absenteeism, study says.

Emerging evidence suggests LB.1 could be more transmissible than earlier Omicron subvariants, but there’s nothing to suggest it will cause more severe disease.
A new study finds the risks of developing long COVID declined over the first two years of the pandemic. But unvaccinated adults were more than twice as likely to get long COVID compared with those who were vaccinated.
Reactions like disgust are part of the behavioral immune system that helps you avoid disease. Usually conservatives are more fearful of contamination – but something unusual happened during COVID-19.
