Key Points

• Since the detection of the first locally transmitted cases of chikungunya in August 2024, a total of 138 cases have been reported. The spread continues, with 38% of cases detected in week 52 occurring in isolated locations, indicating outbreaks outside known clusters and in new municipalities that were previously free of the disease. The transition to an epidemic situation appears highly likely in the short term.

• The situation regarding dengue remains very calm.
