Outbreaks of poliomyelitis in Costa Rica occurred at variable intervals until 1972. The first campaign with Salk vaccine was in 1956 and the first with Sabin vaccine was in 1959. Since then, campaigns have been irregular, depending on the occurrence of outbreaks. Continuous vaccination programs were inaugurated after the last outbreak in 1972, and the coverage of primary health care in rural areas was extended. These programs resulted in high levels of immunization. Since no cases of poliomyelitis have occurred in the last 10 years, we can say confidently that the disease has been eradicated in Costa Rica.
直到1972年，哥斯达黎加曾间歇性地爆发脊髓灰质炎。1956年首次开展使用索尔克疫苗的接种运动，1959年首次开展使用萨宾疫苗的接种运动。从那时起，接种运动一直不规律，取决于疫情的发生情况。1972年最后一次疫情爆发后启动了持续的疫苗接种计划，并扩大了农村地区初级卫生保健的覆盖范围。这些计划带来了高免疫水平。由于过去10年未出现脊髓灰质炎病例，我们可以有把握地说，脊髓灰质炎在哥斯达黎加已被根除。
