The study, published in the journal Nature Communications, focused on the re-emergence of African swine fever (ASF) in Europe in recent years. ASF is a highly contagious viral disease that affects pigs and can cause significant economic losses.
The researchers analyzed the genomes of ASF viruses collected from outbreaks in Europe between 2014 and 2018. They found that the viruses belonged to two distinct genetic lineages, one of which was associated with outbreaks in Eastern Europe and the other with outbreaks in Western Europe.
The researchers also found that the viruses from the Eastern European lineage had undergone genetic changes that enabled them to spread more easily between pigs and survive in the environment for longer periods of time. These changes likely contributed to the rapid spread of ASF in Eastern Europe and its subsequent re-emergence in Western Europe.
The findings of the study highlight the importance of genomic surveillance in tracking and understanding the spread of infectious diseases. By understanding the genetic characteristics of viruses, researchers can better predict how they will behave and develop more effective strategies for preventing and controlling outbreaks.
In addition to the genetic characteristics of the virus, other factors such as changes in pig farming practices and increased movement of animals are also thought to have contributed to the re-emergence of ASF in Europe.
Understanding the complex interplay between viral genetics, animal husbandry practices, and environmental conditions is essential for developing effective strategies to prevent and control future outbreaks of ASF and other infectious diseases.
