👉 The Dad Flu, also known as Parainfluenza Virus Type 3 (PIV3), is a viral infection that primarily affects children and young adults, causing symptoms similar to those of the common cold but often more severe. It is characterized by a range of flu-like symptoms including cough, sore throat, runny nose, and fever, sometimes accompanied by wheezing or difficulty breathing. The term "Dad Flu" gained popularity due to its frequent association with respiratory issues in fathers, though it can affect anyone. Unlike the more common Influenza virus, the Dad Flu is not typically treated with antiviral medications but can be managed with supportive care such as rest, hydration, and over-the-counter medications for symptoms like cough and fever. Vaccines are available to help prevent severe cases, especially in high-risk groups.
