Air sampling detects equine herpesviruses at major equestrian events in Spain and the United States

Air sampling at equestrian events could detect equine herpesviruses, offering a new monitoring method. Researchers found EHV-1 and EHV-4 in air samples at international events in Spain and the US, suggesting viral presence even without visible symptoms. This non-invasive approach, inspired by public health practices, could enhance biosecurity at large gatherings, though current equipment costs limit widespread use.
