Potential for Introduction of African Swine Fever Virus into High-Biosecurity Pig Farms by Flying Hematophagous Insects.

ABSTRACT:

Background

DNA of African swine fever virus (ASFV) has previously been detected in hematophagous insects on ASF outbreak farms. However, it remains unclear whether the viral DNA derived from blood meals that originated from pigs on the outbreak farm or was introduced from infected domestic pigs or wild boar sources located outside of the outbreak farm.

Methods

We caught 644 hematophagous insects on the windows at two non-outbreak high-biosecurity pig farms (i.e., without ASFV-infected pigs) using plastic meshes coated with sticky glue, as well as 3576 hematophagous insects using H-traps on or around the farms. Using PCR analyses, we identified which insects were present, whether these hematophagous insects carried blood from an external (exogenous) source and if the blood co
