What is one of the main transmission methods for EHV to horses?

Aerosolized transmission from coughing is a significant way that Equine Herpesvirus (EHV) spreads among horses. When an infected horse coughs or sneezes, respiratory droplets containing the virus are released into the air and can be inhaled by other horses nearby, making this a highly effective means of transmission. This route of spread highlights the importance of managing environments where horses reside, particularly during outbreaks of respiratory illness.

In contrast, while contaminated ground feed or water supply could theoretically contribute to spreading other types of pathogens, they are not primary modes for EHV transmission. Additionally, while direct contact with humans can introduce various pathogens, it does not play a major role in the transmission of EHV between horses. Therefore, understanding aerosol transmission is crucial for effective disease prevention and management in equine populations.
