Costa Rica dengue cases up 34% vs 2025; Alajuela, Grecia, Orotina lead

Costa Rica reports a 34% year-over-year increase in dengue cases, with Alajuela, Grecia, and Orotina recording the highest cumulative counts by epidemiological week 34. The rise signals a worsening outbreak trajectory, though the source is a single university publication and lacks national totals or severity data. This matters for public-health resource allocation and regional outbreak monitoring.
