From the Respiratory Disease Epidemiologist - October 16, 2020

Tomorrow is the end of the third week of the 2020-2021 influenza season. Unfortunately, dissemination of summer influenza surveillance as well as the start of weekly reporting for this season has been delayed as we continue our response to the COVID-19 pandemic. Over the summer, influenza activity remained low and below baselines. So far for the 2020-2021 season, influenza detections remain at levels normal for this time of year. However, the percentages of healthcare visits for influenza-like illness reported by our sentinel network is high, and we are currently investigating whether that has to do with COVID-19 illnesses, illnesses from another respiratory pathogen, or with changes in patient care and healthcare seeking behaviors since the pandemic.

Getting your influenza vaccination this year is especially critical in order to prevent a "twindemic" of influenza and COVID-19 this winter. Influenza vaccination not only prevents influenza illnesses but also lessens the severity of influenza illness and prevents associated hospitalizations and death. Find a location providing influenza vaccinations at Check with your local health department or health system, as they may be conducting drive-thru vaccination events.

Influenza-like illness (fever with cough or sore throat) can be caused by several respiratory pathogens including the novel coronavirus. The CDC has guidance for what to do if you get sick with either influenza orĀ  COVID-19, including what emergency signs warrant immediate medical attention.
