Key result
Contact with warthogs or their carcasses was the predominant cause of 59 African swine fever outbreaks involving at least 4,031 domestic pigs in the South African controlled area from 1977 to 2017.
Why the study?
Spillover occasionally occurs from the sylvatic cycle of African swine fever involving warthogs and argasid ticks to domestic pigs, causing outbreaks.
Observational (n=4,031)
Yes
Spillover of African swine fever from the sylvatic cycle to domestic pigs continues to occur in South Africa, highlighting the need for appropriate biosecurity measures.
No takes yet. Share an insight, caveat, or question.
Spillover outbreaks persist in the controlled area; leaves open whether current delineation strategies adequately protect domestic pigs.
Rensburg et al. (2020) conducted an observational in African swine fever (n=4,031). Contact with warthogs or warthog carcasses was evaluated on African swine fever outbreaks. Contact with warthogs or their carcasses was the predominant cause of 59 African swine fever outbreaks involving at least 4,031 domestic pigs in the South African controlled area from 1977 to 2017.
