According to the Centers for Disease Control and Prevention (CDC), influenza-like illness activity, including cold or flu symptoms, is now widespread in 48 states, making this the worst flu season since 2003. From 2010 to 2019, the annual death rate from the flu increased from approximately 12,000 deaths per year in 2011-2012 to 2018-2019.

Distinguishing Between Cold and Flu Symptoms

As cold and flu season continues, Exergen Corporation, the maker of the Temporal Scanner thermometer, is educating people on how to tell the difference between the cold and the flu. While cold and flu symptoms are typically the same – sore throat, runny nose, fatigue – only the flu is accompanied by a fever. 

The Importance of Fever Detection in Flu Diagnosis

To ensure your child- or anyone- does not have the flu, take their temperature to ensure they do not have a fever. Since fever is really the only way to detect the flu, it’s important to have a reliable thermometer on hand that will fast and accurate reading’” said Francesco Pompei, Ph.D. CEO of Exergen Corporation. “While flu vaccination is recommended by the CDC, it is not 100percent effective – often less than 50 percent – so vigilance is important even if you have received a flu vaccine.”

To ensure accurate fever detection during the flu season, consider using the Exergen Temporal Scanner, designed for quick and precise temperature readings.

CDC Recommendations for Cold and Flu Symptoms

The CDC advises those whose concerns to contact their physician before going to the ER or a hospital. This may protect someone who doesn’t have the flu and prevent the spread from those who do. It is important to monitor symptoms, especially fever on an ongoing basis.
