A focal outbreak of highly fatal disease occurred in eastern Costa Rica in 1974. No rickettsial spotted fevers have previously been reported in Costa Rica. Nevertheless, the available evidence points to an unidentified rickettsial pathogen, probably of the spotted fever group, as the agent responsible for this outbreak.
1974年，哥斯达黎加东部发生了一起高致死性疾病的局部暴发。此前，哥斯达黎加未曾报告过立克次体斑疹热。然而，现有证据表明，一种身份不明的立克次体病原体（可能属于斑疹热群）是此次疫情的病原体。
