Protecting Yourself During a Twindemic


Twindemic refers to the dual threat of a severe influenza (flu) outbreak coinciding with the COVID-19 pandemic in the fall and winter of 2020. Flu and COVID-19 are both contagious respiratory illnesses but are caused by different viruses. Health experts say because some of the flu and COVID-19 symptoms are so similar, it may be hard to tell the difference between them based on symptoms alone. Health care professionals urge everyone to get a flu vaccine.
