Population
Asymptomatic domestic pigs (1,134 serum, 300 whole blood) and soft ticks in selected Zambian provinces

May inform inter-epidemic ASF surveillance in Zambia; leaves open the role of asymptomatic carriers in persistence.
The study confirms ASF endemicity in Eastern Province and the presence of ASFV-infected ticks in Southern Province, providing evidence for exposure of domestic pigs to ASFV in non-endemic regions during inter-epidemic periods.
Chambaro et al. (2020) studied this question.
