Hospital hygiene: A closer look reveals realistic frequency of infection
A research team led by Inselspital, Bern University Hospital and the University of Bern found a correlation between the frequency of infections after surgery and performance in quality audits. Lower surgical site infection rates correlate with a lower audit score. In other words, looking more closely reveals more reported infections. Recommendations for possible correction are presented.

Richness of plant species reduces the number of viral infections in meadows
A new study indicates that agricultural activity confuses the mechanisms that regulate the occurrence of plant diseases in nature. A wider variety of virus species was found in meadows close to agricultural fields compared to those located in natural surroundings, with the richness of plant species having no effect on the number of virus species. However, maintaining biodiversity is worthwhile, as plant richness did reduce the number of viral infections in the meadows. (2021-02-08)
