National Influenza Activity: • Due to the federal shut down of government offices, the CDC FluView report has not been published. Therefore there are no updates on influenza activity in the US at this time.
Influenza Activity in Massachusetts For more information about flu, please go to our Viral Respiratory Disease Dashboard which includes information not only on influenza but also other acute respiratory diseases, COVID-19, and respiratory syncytial virus (RSV), wastewater data and immunizations for respiratory diseases.
The figure below shows that for MMWR week 42, the percent of ILI visits in the current week is below the regional baseline of 2.2%. (The CDC uses trends from past years to determine a region-specific baseline rate of ILI visits, which for Massachusetts is 2.2%. A rate above this regional baseline indicates higher than normal levels of ILI in the state.) For more information on how regional baselines are calculated see CDC’s influenza surveillance website at U.S. Influenza Surveillance: Purpose and Methods | FluView | CDC) For more information on weekly flu activity, see CDC’s influenza surveillance website at https://www.cdc.gov/fluview/surveillance/index.html. |
