Despite the high number of infections from this contagious viral disease, the fatality rate remained at 0.10 percent—equivalent to one death for every thousand registered cases—the ministry reported.

The highest incidence of the disease continued to be in the central region (the capital municipality) with 10,248 cases, followed by the departments of Quetzaltenango (2,183), Solola (1,367), Izabal (1,199), and Totonicapan (1,016).

Weekly case numbers showed a decline compared to the peak observed last March, although experts warned that the outbreak remains active; meanwhile, the most severe complications continue to affect young children, malnourished individuals, and patients with risk factors.

The current situation arose following a large-scale religious gathering held in December 2025 in the municipality of Santiago Atitlan, Solola.

Guatemala had not recorded an endemic outbreak of this magnitude since 1997, nor an imported one since 2018, according to reports.
