Abstract
Classical Swine Fever (CSF) is an endemic disease in Cuba, and an eradication strategy by zones is planned by the Official Veterinary Service. The aim of this study was to identify high-risk areas of CSF and the risk factors associated with the disease occurrence in the Pinar del Río province, one of the prioritized areas in the eradication strategy. The outbreak occurrence at district level was analyzed through a 7-year period (2009 to 2015). A high-risk cluster (RR = 5.13, 95% CI 3.49–7.56) was detected during the last 2 years of the study period in the eastern half of the province, with 38 out of 97 districts included. The rate of CSF-affected holdings had a significant increase during 2014–2015 and seems to have occurred mainly in the high-risk cluster area. Swine population density by district (heads/km2) and road length (km) by district were associated with the disease outbreak occurrence. These results provide new insights into the knowledge of the epidemiology of the disease in Cuban endemic conditions and can contribute to improving the control and the eradication strategy in this situation.
Highlights
Classical swine fever (CSF) is a highly contagious viral disease caused by an RNA virus belonging to the genus Pestivirus, family Flaviviridae [1,2,3]
The present paper describes the results of a study for the identification of spatiotemporal clusters and risk factors for CSF in Pinar del Rio province
A significant high-risk cluster (RR = 5.13, 95% confidence intervals (95% CI) 3.49–7.56) of CSF outbreaks at district level (Table 2 and Figure 2) was detected during the last 2 years (2014–2015) of the study period
Summary
Classical swine fever (CSF) is a highly contagious viral disease caused by an RNA virus belonging to the genus Pestivirus, family Flaviviridae [1,2,3]. CSF is a disease notifiable to the World Organization for Animal Health (OIE) and one of the most highly contagious animal diseases, with high morbidity and mortality in susceptible hosts, depending on the virus strain, immune status of the herd, and age of the pigs [7]. The epidemiological forward and backward tracing of transmission contacts is required. These basic measures, might not always be sufficient to achieve a rapid disease eradication, and supplementary control measures, such as preemptive culling of animals near infected premises or emergency vaccination, may help to control the disease [11]
