Costa Rica intensifies dengue control in Ciudad Quesada after four confirmed cases

Costa Rican health authorities confirmed four dengue cases in Ciudad Quesada and launched vector control operations in Barrio San Antonio through October 22, including home visits, breeding site elimination, and fumigation. The response is localized and routine, with no indication of broader outbreak or unusual severity. The development matters as a public-health measure but carries no significant market or geopolitical implications.
