[An apparent outbreak of rickettsial disease in Costa Rica, 1974].

Human rickettsial infections are reported every year throughout Latin America. The majority of those described are cases of murine typhus caused by Rickettsiu ty$hi. In addition, well-established foci of epidemic (R. prowazekii) typhus exist in the mountains of Bolivia and Guatemala (I, Z), and R. rickettsii (Rocky Mountain spotted fever) infections have been reported in various Latin American countries. In contrast, Panama is the only country along the Central American isthmus that has reported cases of rickettsial spotted fevers (3, 4).

This article deals with an isolated disease outbreak in northeastern Costa Rica which
