👉 Perronaviruses are a family of RNA viruses that cause respiratory infections in humans, particularly those infected with the influenza virus. They are characterized by their ability to infect and replicate within host cells, often causing severe symptoms such as coughing, fever, and pneumonia. This family is notable for its association with the influenza pandemic in 1918-1919, where it was responsible for a significant loss of life and economic damage worldwide.
