According to the Hanoi Center for Disease Control (CDC), the city saw 212 measles cases across 30 districts, wards, and towns from April 4th to 11th, with no fatalities reported.
Several districts reported higher numbers of cases: Nam Từ Liêm (46), Long Biên (17), Hoàng Mai (16), Tây Hồ (12), Hà Đông (11), and Đống Đa, Thanh Trì, Thanh Xuân (10 each).
The CDC attributes the increase in measles to a lack of vaccination or incomplete vaccination among affected individuals, particularly those over six years old, and anticipates a continued rise in cases.

The cumulative total for 2025 stands at 976 cases, with no fatalities, a rise compared to 2024 (585 cases/0 deaths). Cases are distributed across all 30 districts, wards, and towns.
