Epidemiological comments In response to the immediate notification of Newcastle disease sent by Costa Rica to the OIE and concerning the province of Guanacaste, the epidemiological surveillance service of the Institute for Animal Health and Protection (IPSA) initiated an epidemiological monitoring in border regions in the south of the country in the municipalities of Cárdenas and San Juan del Sur. In a locality called El Progreso, Cárdenas, sick poultry was found with signs consistent with Newcastle disease. In this situation, movement control of poultry was implemented in the affected zone. On 29 April, samples were taken and immediately sent to the IPSA National Veterinary Diagnosis Laboratory on 30 April 2015; the diagnosis was confirmed on 6 May 2015, then all susceptible population in the outbreak zone was culled. On 5 May, the Direction for Animal Health launched a vaccination campaign against the disease in 33 border communities in the municipalities of Cárdenas and San Juan del Sur; 12,975 poultry from 811 owners were vaccinated. Also, 33 talks were given to 812 poultry owners in both municipalities.
