China has witnessed a significant downturn in influenza activity, with national surveillance data indicating a descent to moderate transmission levels across most regions. According to the latest epidemiological report from the Chinese Center for Disease Control and Prevention, the country’s flu positivity rate among influenza-like illness cases dropped to 41.9% during the week beginning December 15, 2025, marking a substantial decrease from the previous week’s 50.2% rate.
The epidemiological landscape shows varied regional patterns, with northern, northeastern, southwestern, and northwestern provinces experiencing the most notable improvements. However, eastern, southern, and central regions continue to report elevated flu activity, maintaining high transmission levels despite the overall national decline.
In parallel developments, educational institutions have reported a dramatic reduction in infection clusters, suggesting effective containment measures in school environments. Meanwhile, respiratory syncytial virus (RSV) has demonstrated an upward trajectory, particularly in northern provinces, indicating a possible epidemiological shift.
The surveillance data further reveals fluctuating patterns for rhinovirus while confirming that SARS-CoV-2 and other monitored respiratory pathogens remain consistently at low prevalence levels, highlighting the specific nature of the current respiratory disease landscape.
