Abstract
African swine fever (ASF) is a devastating disease in domestic and wild pigs. Since the first outbreak of ASF in August 2018 in China, the disease has spread throughout the country with an unprecedented speed, causing heavy losses to the pig and related industries. As a result, strategies for managing the disease are urgently needed. This paper summarizes the important aspects of three key elements about African swine fever virus (ASFV) transmission, including the sources of infection, transmission routes, and susceptible animals. It overviews the relevant prevention and control strategies, focusing on the research progress of ASFV vaccines, anti-ASFV drugs, ASFV-resistant pigs, efficient disinfection, and pig farm biosecurity. We then reviewed the key technical points concerning pig farm repopulation, which is critical to the pork industry. We hope to not only provide a theoretical basis but also practical strategies for effective dealing with the ASF epidemic and restoration of pig production.
Highlights
African swine fever (ASF) is a highly contagious viral disease caused by African swine fever virus (ASFV) infection, with morbidity and mortality rates close to 100% [1,2]
This review summarizes the key elements in ASFV transmission, prevention, and control and provides key technical insight to pig farm repopulation
It was found that the titer of ASFV in the air was positively correlated with the amount of virus excreted from feces
Summary
African swine fever (ASF) is a highly contagious viral disease caused by African swine fever virus (ASFV) infection, with morbidity and mortality rates close to 100% [1,2]. This disease was first reported in Kenya in 1921, and several important intercontinental transmissions have occurred since [3,4,5]. It can be speculated that the direct economic loss caused by ASF pandemics in China is much greater than that. This review summarizes the key elements in ASFV transmission, prevention, and control and provides key technical insight to pig farm repopulation
