Research funded by the European Food Safety Authority (EFSA) has found that blood-sucking insects, collected from large-scale pig farms with African swine fever, carry the PPA virus. The study, conducted by researchers from the University of Agricultural Sciences and Veterinary Medicine in Cluj-Napoca, and two other Romanian veterinary institutes, suggests that these insects may play a significant role in the transmission of the infection. The higher rate of spread observed during the summer months underscores the importance of blood-sucking insects in the epidemiology of African swine fever in large-scale farming settings.
