疾病控制与预防中心表示将继续按周更新呼吸道疾病活动水平。本篇为跟进报道：与此前流感单项数据相比，本次更新给出了流感、呼吸道合胞病毒和新冠三者的综合活动水平及11月13日的最新判断。
CDC Updates Respiratory Illness Data on November 13: Activity Low but Increasing, With Flu Rising in Many Areas
The U.S. Centers for Disease Control and Prevention updated its Respiratory Illnesses Data Channel on November 13, 2026. The latest data show that the amount of acute respiratory illness causing people to seek health care in the United States is low but increasing.
By virus, seasonal flu activity continues to increase in many parts of the country. Respiratory syncytial virus activity is low in most areas of the country, and COVID-19 activity is low nationally.
The CDC also reported that rhinovirus/enterovirus and respiratory adenovirus are elevated nationally, with respiratory adenovirus increasing in some regions of the country.
The data channel brings together emergency department visits, laboratory testing, wastewater surveillance and hospitalization reporting. It is maintained by the National Center for Immunization and Respiratory Diseases, and the data are preliminary and may change as more reports are received.
The CDC said it will continue to update respiratory illness activity levels weekly. This is a follow-up report: compared with earlier flu-only figures, the November 13 update provides a combined assessment of flu, respiratory syncytial virus and COVID-19 activity.
