ASF local spread transmission probabilities

Look-up table with daily probabilities of a susceptible holding becoming infected with African swine fever through local spread, based on distance from an infectious holding. Given as four distinct distance bands with positive probabilities (indicating potential transmission) for distances up to 2 km, and a band with probability 0 for distances >= 2 km. Local spread is deemed to include, for example, transmission via rodents and insects, unregistered animal movements, and sharing of equipment and tools.

Format

A data frame (tibble) with 5 rows and 3 columns:

lower_boundary

Lower boundary of each distance band (inclusive), in meters.

upper_boundary

Upper boundary of each distance band (exclusive), in meters.

probability

Daily probability of infection through local spread, given a distance from an infectious holding between lower_boundary and upper_boundary.
