Western Pacific Region
In the Western Pacific Region, sentinel surveillance data have been reported by ten countries and areas via test positivity rates from sentinel sites in 2025. In the past month, the test positivity rate increased from 5% in EW14 to 11% in EW19. Following lower circulation in the first ten weeks of the year, a sharp upwards trend reached similar levels as last year (10% in EW18 2024). The recent increases have been observed in four countries and areas to date: Cambodia, China, Hong Kong SAR and Singapore.
