Key result
Shipments of live pigs and proximity to an infected herd within 500 meters were major drivers of classical swine fever transmission, with estimated transmission rates of 0.065 per contact and 0.027 per week, respectively.
Observational (n=403)
Effect estimate: 0.0647 per contact (95% CI 0.0043-0.1251)
Quantifying the transmission rates of classical swine fever virus by different contact types provides essential data to optimize control strategies for future epidemics.

Contact-specific transmission rates guide targeted biosecurity; leaves open applicability to modern herds and control strategies.
Stegeman et al. (2002) conducted an observational in Classical swine fever (n=403). Inter-herd contacts (e.g., live pigs, lorries, persons, artificial insemination, neighborhood proximity) was evaluated on Rate of transmission per shipment of live pigs (0.0647 per contact, 95% CI 0.0043-0.1251). Shipments of live pigs and proximity to an infected herd within 500 meters were major drivers of classical swine fever transmission, with estimated transmission rates of 0.065 per contact and 0.027 per week, respectively.
